object
spec object required
spec defines the desired state of InferenceService
affinity object
Affinity constrains inference Pod placement (node/pod affinity and
anti-affinity). Passthrough to the Pod spec, for finer control than
NodeSelector — e.g. preferring or avoiding nodes already running other
GPU workloads.
nodeAffinity object
Describes node affinity scheduling rules for the pod.
preferredDuringSchedulingIgnoredDuringExecution []object
The scheduler will prefer to schedule pods to nodes that satisfy
the affinity expressions specified by this field, but it may choose

most preferred is the one with the greatest sum of weights, i.e.
for each node that meets all of the scheduling requirements (resource
request, requiredDuringScheduling affinity expressions, etc.),
compute a sum by iterating through the elements of this field and adding
"weight" to the sum if the node matches the corresponding matchExpressions; the
node(s) with the highest sum are the most preferred.

CacheTypeCustomV sets a custom KV cache type for values that is not in the
standard enum. See CacheTypeCustomK for usage notes. Takes precedence over
CacheTypeV when both are set.
cacheTypeK

2.097152e+06disruption object
Disruption controls how the operator manages node-disruption annotations
on inference pods during the vulnerable startup window (model download +
load). When ProtectStartup is true (the default), the operator sets
karpenter.sh/do-not-disrupt: "true" on the pod template while the
InferenceService is not yet Ready, then removes it once the service
reaches the Ready phase. Set ProtectAlways to true to keep the annotation
permanently (equivalent to setting it via podAnnotations). User-provided
podAnnotations always win on collision.
protectAlways
boolean
ProtectAlways keeps the disruption-protection annotation on the pod
template permanently, regardless of the InferenceService phase. This is
equivalent to setting karpenter.sh/do-not-disrupt: "true" via
podAnnotations, but managed by the operator. Defaults to false.
protectStartup
boolean
ProtectStartup prevents node disruption (e.g., Karpenter consolidation,
Cluster Autoscaler scale-down) while the InferenceService is starting up.
When true, the operator sets karpenter.sh/do-not-disrupt: "true" on the
pod template until the InferenceService reaches the Ready phase, then
removes it. Defaults to true.
endpoint object
Endpoint defines the service endpoint configuration
gateway object
Gateway opts this InferenceService into Envoy AI Gateway exposure. When
set and Enabled, the operator generates the Backend / AIServiceBackend /
AIGatewayRoute resources that front this service through a pre-installed
Envoy AI Gateway. nil (the default) preserves today's behavior (no
gateway resources). The Envoy AI Gateway stack and the referenced Gateway
are a documented prerequisite; LLMKube does not install or own them.
enabled
boolean
Enabled is the opt-in switch. When false (or when Gateway is nil), the
operator generates no gateway resources for this InferenceService.
gatewayRef object required
GatewayRef identifies the pre-installed Gateway (gateway.networking.k8s.io)
the generated AIGatewayRoute attaches to. The Gateway typically lives in a
dedicated gateway namespace; cross-namespace attachment requires the
Gateway listener's allowedRoutes.namespaces to permit this
InferenceService's namespace (a documented prerequisite for the MVP; the
operator does not generate ReferenceGrants or touch the listener).
name
string required
Name is the Gateway's name.
namespace
string
Namespace is the Gateway's namespace. Empty means the InferenceService's
own namespace.
modelName
string
ModelName is the OpenAI "model" string clients send, matched by the
generated route rule (the x-ai-eg-model header the gateway's ext_proc
populates from the request body). Defaults to ModelRef, falling back to
the InferenceService name when ModelRef is empty.
nodePort
integer
NodePort is the specific NodePort to pin when endpoint.type is NodePort.
If set, the Service will use this exact port instead of auto-assigning
from the 30000-32767 range. This provides a stable external endpoint
across redeployments.

Name of the environment variable.
May consist of any printable ASCII characters except '='.
value
string
Variable references $(VAR_NAME) are expanded
using the previously defined environment variables in the container and
any service environment variables. If a variable cannot be resolved,
the reference in the input string will be unchanged. Double $$ are reduced
to a single $, which allows for escaping the $(VAR_NAME) syntax: i.e.
"$$(VAR_NAME)" will produce the string literal "$(VAR_NAME)".
Escaped references will never be expanded, regardless of whether the variable
exists or not.
Defaults to "".
valueFrom object
Source for the environment variable's value. Cannot be used if value is not empty.
configMapKeyRef object
Selects a key of a ConfigMap.
key
string required

the environment variable will not be set in the Pod's containers.
If optional is set to false and the specified key does not exist,
an error will be returned during Pod creation.

evictionProtection
boolean
EvictionProtection marks this service as ineligible for memory-pressure
eviction by the metal-agent watchdog. Use this for production workloads
that should never be silently stopped under memory pressure, even when
they are the lowest-priority option. The agent's per-process pickEvictionTarget
excludes protected processes from the eviction-candidate set; the
MemoryPressure status condition is still patched on protected services
for operator visibility.
Has no effect when --eviction-enabled is unset on the metal-agent or
for non-llama-server runtimes (oMLX, Ollama). Defaults to false.
extraArgs

recursively.
If ReadOnly is false, this field has no meaning and must be unspecified.
If ReadOnly is true, and this field is set to Disabled, the mount is not made
recursively read-only. If this field is set to IfPossible, the mount is made
recursively read-only, if it is supported by the container runtime. If this
field is set to Enabled, the mount is made recursively read-only if it is
supported by the container runtime, otherwise the pod will not be started and
an error will be generated to indicate the reason.
If this field is set to IfPossible or Enabled, MountPropagation must be set to
None (or be unspecified, which defaults to None).
If this field is not specified, it is treated as an equivalent of Disabled.
subPath
string
Path within the volume from which the container's volume should be mounted.
Defaults to "" (volume's root).
subPathExpr
string
Expanded path within the volume from which the container's volume should be mounted.

Defaults to "" (volume's root).
SubPathExpr and SubPath are mutually exclusive.
extraVolumes []object
ExtraVolumes adds additional Volumes to the inference Pod, appended
after the model-storage volumes built from ModelRef. Useful for a

string pattern:
^(\+|-)?(([0-9]+(\.[0-9]*)?)|(\.[0-9]+))(([KMGTPE]i)|[numkMGTPE]|([eE](\+|-)?(([0-9]+(\.[0-9]*)?)|(\.[0-9]+))))?$ephemeral object
ephemeral represents a volume that is handled by a cluster storage driver.
The volume's lifecycle is tied to the pod that defines it - it will be created before the pod starts,
and deleted when the pod is removed.
Use this if:
a) the volume is only needed while the pod runs,
b) features of normal volumes like restoring from snapshot or capacity
tracking are needed,
c) the storage driver is specified through a storage class, and
d) the storage driver supports dynamic volume provisioning through
a PersistentVolumeClaim (see EphemeralVolumeSource for more
information on the connection between this volume type
and PersistentVolumeClaim).
Use PersistentVolumeClaim or one of the vendor-specific
APIs for volumes that persist for longer than the lifecycle
of an individual pod.
Use CSI for light-weight local ephemeral volumes if the CSI driver is meant to
be used that way - see the documentation of the driver for
more information.
A pod can use both types of ephemeral volumes and
persistent volumes at the same time.
volumeClaimTemplate object
Will be used to create a stand-alone PVC to provision the volume.
The pod in which this EphemeralVolumeSource is embedded will be the
owner of the PVC, i.e. the PVC will be deleted together with the
pod. The name of the PVC will be `<pod name>-<volume name>` where
`<volume name>` is the name from the `PodSpec.Volumes` array
entry. Pod validation will reject the pod if the concatenated name
is not valid for a PVC (for example, too long).
An existing PVC with that name that is not owned by the pod
will *not* be used for the pod to avoid using an unrelated
volume by mistake. Starting the pod is then blocked until
the unrelated PVC is removed. If such a pre-created PVC is
meant to be used by the pod, the PVC has to updated with an
owner reference to the pod once the pod exists. Normally
this should not be necessary, but it may be useful when
manually reconstructing a broken cluster.
This field is read-only and no changes will be made by Kubernetes
to the PVC after it has been created.
Required, must not be nil.
metadata
object
May contain labels and annotations that will be copied into the PVC
when creating it. No other fields are allowed and will be rejected during
validation.
spec object required
The specification for the PersistentVolumeClaim. The entire content is
copied unchanged into the PVC that gets created from this
template. The same fields as in a PersistentVolumeClaim
are also valid here.
accessModes
[]string
accessModes contains the desired access modes the volume should have.
More info: https://kubernetes.io/docs/concepts/storage/persistent-volumes#access-modes-1
dataSource object
dataSource field can be used to specify either:
* An existing VolumeSnapshot object (snapshot.storage.k8s.io/VolumeSnapshot)
* An existing PVC (PersistentVolumeClaim)
If the provisioner or an external controller can support the specified data source,
it will create a new volume based on the contents of the specified data source.
When the AnyVolumeDataSource feature gate is enabled, dataSource contents will be copied to dataSourceRef,
and dataSourceRef contents will be copied to dataSource when dataSourceRef.namespace is not specified.
If the namespace is specified, then dataSourceRef will not be copied to dataSource.
apiGroup
string

If APIGroup is not specified, the specified Kind must be in the core API group.
For any other third-party types, APIGroup is required.
kind
string required
Kind is the type of resource being referenced
name
string required
Name is the name of resource being referenced
dataSourceRef object
dataSourceRef specifies the object from which to populate the volume with data, if a non-empty
volume is desired. This may be any object from a non-empty API group (non
core object) or a PersistentVolumeClaim object.
When this field is specified, volume binding will only succeed if the type of
the specified object matches some installed volume populator or dynamic
provisioner.
This field will replace the functionality of the dataSource field and as such
if both fields are non-empty, they must have the same value. For backwards
compatibility, when namespace isn't specified in dataSourceRef,
both fields (dataSource and dataSourceRef) will be set to the same
value automatically if one of them is empty and the other is non-empty.
When namespace is specified in dataSourceRef,
dataSource isn't set to the same value and must be empty.
There are three important differences between dataSource and dataSourceRef:
* While dataSource only allows two specific types of objects, dataSourceRef
allows any non-core object, as well as PersistentVolumeClaim objects.
* While dataSource ignores disallowed values (dropping them), dataSourceRef
preserves all values, and generates an error if a disallowed value is
specified.
* While dataSource only allows local objects, dataSourceRef allows objects
in any namespaces.
(Beta) Using this field requires the AnyVolumeDataSource feature gate to be enabled.
(Alpha) Using the namespace field of dataSourceRef requires the CrossNamespaceVolumeDataSource feature gate to be enabled.
apiGroup
string
APIGroup is the group for the resource being referenced.
If APIGroup is not specified, the specified Kind must be in the core API group.
For any other third-party types, APIGroup is required.

matchLabels
object
matchLabels is a map of {key,value} pairs. A single {key,value} in the matchLabels
map is equivalent to an element of matchExpressions, whose key field is "key", the
operator is "In", and the values array contains only "value". The requirements are ANDed.
storageClassName
string
storageClassName is the name of the StorageClass required by the claim.
More info: https://kubernetes.io/docs/concepts/storage/persistent-volumes#class-1
volumeAttributesClassName
string
volumeAttributesClassName may be used to set the VolumeAttributesClass used by this claim.
If specified, the CSI driver will create or update the volume with the attributes defined
in the corresponding VolumeAttributesClass. This has a different purpose than storageClassName,
it can be changed after the claim is created. An empty string or nil value indicates that no
VolumeAttributesClass will be applied to the claim. If the claim enters an Infeasible error state,
this field can be reset to its previous value (including nil) to cancel the modification.
If the resource referred to by volumeAttributesClass does not exist, this PersistentVolumeClaim will be
set to a Pending state, as reflected by the modifyVolumeStatus field, until such as a resource
exists.

image object
image represents an OCI object (a container image or artifact) pulled and mounted on the kubelet's host machine.
The volume is resolved at pod startup depending on which PullPolicy value is provided:
- Always: the kubelet always attempts to pull the reference. Container creation will fail If the pull fails.
- Never: the kubelet never pulls the reference and only uses a local image or artifact. Container creation will fail if the reference isn't present.
- IfNotPresent: the kubelet pulls if the reference isn't already present on disk. Container creation will fail if the reference isn't present and the pull fails.
The volume gets re-resolved if the pod gets deleted and recreated, which means that new remote content will become available on pod recreation.
A failure to resolve or pull the image during pod startup will block containers from starting and may add significant latency. Failures will be retried using normal volume backoff and will be reported on the pod reason and message.
The types of objects that may be mounted by this volume are defined by the container runtime implementation on a host machine and at minimum must include all valid types supported by the container image field.
The OCI object gets mounted in a single directory (spec.containers[*].volumeMounts.mountPath) by merging the manifest layers in the same way as for container images.
The volume will be mounted read-only (ro).
Sub path mounts for containers are not supported (spec.containers[*].volumeMounts.subpath) before 1.33.
The field spec.securityContext.fsGroupChangePolicy has no effect on this volume type.
pullPolicy
string
Policy for pulling OCI objects. Possible values are:
Always: the kubelet always attempts to pull the reference. Container creation will fail If the pull fails.
Never: the kubelet never pulls the reference and only uses a local image or artifact. Container creation will fail if the reference isn't present.
IfNotPresent: the kubelet pulls if the reference isn't already present on disk. Container creation will fail if the reference isn't present and the pull fails.
Defaults to Always if :latest tag is specified, or IfNotPresent otherwise.
reference
string
Required: Image or artifact reference to be used.
Behaves in the same way as pod.spec.containers[*].image.
Pull secrets will be assembled in the same way as for the container image by looking up node credentials, SA image pull secrets, and pod spec image pull secrets.

Kubelet performs aggressive normalization of the PEM contents written
into the pod filesystem. Esoteric PEM features such as inter-block
comments and block headers are stripped. Certificates are deduplicated.
The ordering of certificates within the file is arbitrary, and Kubelet
may change the order over time.

podCertificate object
Projects an auto-rotating credential bundle (private key and certificate
chain) that the pod can use either as a TLS client or server.
Kubelet generates a private key and uses it to send a
PodCertificateRequest to the named signer. Once the signer approves the
request and issues a certificate chain, Kubelet writes the key and
certificate chain to the pod filesystem. The pod does not start until
certificates have been issued for each podCertificate projected volume
source in its spec.
Kubelet will begin trying to rotate the certificate at the time indicated
by the signer using the PodCertificateRequest.Status.BeginRefreshAt
timestamp.
Kubelet can write a single file, indicated by the credentialBundlePath
field, or separate files, indicated by the keyPath and
certificateChainPath fields.
The credential bundle is a single file in PEM format. The first PEM
entry is the private key (in PKCS#8 format), and the remaining PEM
entries are the certificate chain issued by the signer (typically,
signers will return their certificate chain in leaf-to-root order).
Prefer using the credential bundle format, since your application code
can read it atomically. If you use keyPath and certificateChainPath,
your application must make two separate file reads. If these coincide
with a certificate rotation, it is possible that the private key and leaf
certificate you read may not correspond to each other. Your application
will need to check for this condition, and re-read until they are
consistent.
The named signer controls chooses the format of the certificate it
issues; consult the signer implementation's documentation to learn how to
use the certificates it issues.
certificateChainPath
string
Write the certificate chain at this path in the projected volume.
Most applications should use credentialBundlePath. When using keyPath
and certificateChainPath, your application needs to check that the key
and leaf certificate are consistent, because it is possible to read the
files mid-rotation.
credentialBundlePath
string
Write the credential bundle at this path in the projected volume.
The credential bundle is a single file that contains multiple PEM blocks.
The first PEM block is a PRIVATE KEY block, containing a PKCS#8 private
key.
The remaining blocks are CERTIFICATE blocks, containing the issued
certificate chain from the signer (leaf and any intermediates).
Using credentialBundlePath lets your Pod's application code make a single
atomic read that retrieves a consistent key and certificate chain. If you
project them to separate files, your application code will need to
additionally check that the leaf certificate was issued to the key.
keyPath
string
Write the key at this path in the projected volume.
Most applications should use credentialBundlePath. When using keyPath
and certificateChainPath, your application needs to check that the key
and leaf certificate are consistent, because it is possible to read the
files mid-rotation.
keyType
string required
The type of keypair Kubelet will generate for the pod.
Valid values are "RSA3072", "RSA4096", "ECDSAP256", "ECDSAP384",
"ECDSAP521", and "ED25519".
maxExpirationSeconds
integer
maxExpirationSeconds is the maximum lifetime permitted for the
certificate.
Kubelet copies this value verbatim into the PodCertificateRequests it
generates for this projection.
If omitted, kube-apiserver will set it to 86400(24 hours). kube-apiserver
will reject values shorter than 3600 (1 hour). The maximum allowable
value is 7862400 (91 days).
The signer implementation is then free to issue a certificate with any
lifetime *shorter* than MaxExpirationSeconds, but no shorter than 3600
seconds (1 hour). This constraint is enforced by kube-apiserver.
`kubernetes.io` signers will never issue certificates with a lifetime
longer than 24 hours.
format:
int32
signerName
string required
Kubelet's generated CSRs will be addressed to this signer.
userAnnotations
object
userAnnotations allow pod authors to pass additional information to
the signer implementation. Kubernetes does not restrict or validate this
metadata in any way.
These values are copied verbatim into the `spec.unverifiedUserAnnotations` field of
the PodCertificateRequest objects that Kubelet creates.
Entries are subject to the same validation as object metadata annotations,
with the addition that all keys must be domain-prefixed. No restrictions
are placed on values, except an overall size limitation on the entire field.
Signers should document the keys and values they support. Signers should
deny requests that contain keys they do not recognize.
secret object
secret information about the secret data to project
items []object
items if unspecified, each key-value pair in the Data field of the referenced
Secret will be projected into the volume as a file whose name is the
key and content is the value. If specified, the listed keys will be
projected into the specified paths, and unlisted keys will not be
present. If a key is specified which is not present in the Secret,
the volume setup will error unless it is marked optional. Paths must be
relative and may not contain the '..' path or start with '..'.
key
string required
key is the key to project.
mode
integer
mode is Optional: mode bits used to set permissions on this file.
Must be an octal value between 0000 and 0777 or a decimal value between 0 and 511.
YAML accepts both octal and decimal values, JSON requires decimal values for mode bits.
If not specified, the volume defaultMode will be used.
This might be in conflict with other options that affect the file
mode, like fsGroup, and the result can be other mode bits set.

string required
path is the relative path of the file to map the key to.
May not be an absolute path.

readOnly defaults to false (read/write). ReadOnly here will force
the ReadOnly setting in VolumeMounts.
secretRef object
secretRef specifies the secret to use for obtaining the StorageOS API
credentials. If not specified, default values will be attempted.
name
string
Name of the referent.
This field is effectively required, but due to backwards compatibility is
allowed to be empty. Instances of this type with an empty value here are
almost certainly wrong.
More info: https://kubernetes.io/docs/concepts/overview/working-with-objects/names/#names
volumeName
string
volumeName is the human-readable name of the StorageOS volume. Volume
names are only unique within a namespace.
volumeNamespace
string
volumeNamespace specifies the scope of the volume within StorageOS. If no
namespace is specified then the Pod's namespace will be used. This allows the
Kubernetes name scoping to be mirrored within StorageOS for tighter integration.
Set VolumeName to any name to override the default behaviour.
Set to "default" if you are not using namespaces within StorageOS.
Namespaces that do not pre-exist within StorageOS will be created.
vsphereVolume object
vsphereVolume represents a vSphere volume attached and mounted on kubelets host machine.
Deprecated: VsphereVolume is deprecated. All operations for the in-tree vsphereVolume type
are redirected to the csi.vsphere.vmware.com CSI driver.
fsType
string
fsType is filesystem type to mount.
Must be a filesystem type supported by the host operating system.
Ex. "ext4", "xfs", "ntfs". Implicitly inferred to be "ext4" if unspecified.
storagePolicyID
string
storagePolicyID is the storage Policy Based Management (SPBM) profile ID associated with the StoragePolicyName.
storagePolicyName
string
storagePolicyName is the storage Policy Based Management (SPBM) profile name.
volumePath
string required
volumePath is the path that identifies vSphere volume vmdk
flashAttention
boolean
FlashAttention enables flash attention for faster prompt processing and
reduced KV cache memory. Maps to llama.cpp --flash-attn flag.
On NVIDIA GPUs requires Ampere or newer (compute capability 8.0+).
On Apple Silicon (Metal agent path) the default is true when this field
is unset, because the wired-collector + flash-attn combination prevents
the ~25% decode degradation observed at long context on Qwen-class
models running on M-series chips.
image
string
Image is the container image for the inference runtime.
For llamacpp runtime, defaults to ghcr.io/ggml-org/llama.cpp:server.
For generic runtime, this field is required.
imagePullSecrets []object
ImagePullSecrets for pulling container images from private registries.
name
string
Name of the referent.
This field is effectively required, but due to backwards compatibility is
allowed to be empty. Instances of this type with an empty value here are
almost certainly wrong.
More info: https://kubernetes.io/docs/concepts/overview/working-with-objects/names/#names
jinja
boolean
Jinja enables Jinja2 chat template rendering for tool/function calling support.
Required when using the OpenAI-compatible API with tools. Maps to llama.cpp --jinja flag.
metadataOverrides
[]string
MetadataOverrides overrides GGUF metadata key-value pairs at model load time.
Each entry is passed as a separate --override-kv flag. Format: key=type:value
(e.g., "qwen35moe.context_length=int:1048576" to extend context window, or
"tokenizer.chat_template.thinking=bool:false" to tweak tokenizer behavior).
Maps to llama.cpp --override-kv flag (one flag per entry).
mode
string
Mode selects how the model is served: "chat" (default) for
chat/completion, "embedding" for /v1/embeddings, "rerank" for /v1/rerank.
For the llamacpp runtime it auto-appends the required flags (embedding ->
--embedding --pooling last; rerank -> --reranking --embedding --pooling
rank); any flag already set in spec.extraArgs wins. When unset, the mode is
inferred from spec.extraArgs / spec.endpoint.path. The resolved value is
always reported in status.mode.
enum:
chat, embedding, rerankmodelCache object
ModelCache overrides where this InferenceService caches model weights:
when claimName is set, the named user-owned PVC is mounted as the
writable model cache (prep + download init containers run against it)
instead of the operator's shared/perService cache PVC. When unset, the
operator-global cache mode applies unchanged.
claimName
string
ClaimName names a pre-existing PersistentVolumeClaim in the
InferenceService's namespace to use as the writable model cache volume.
Weights land under the usual <cacheKey>/ subdirectory of the claim, so
RefreshPolicy and cache-key semantics are unchanged and multiple models
can share one claim without colliding. The claim must already exist:
when it is missing the InferenceService is marked Degraded rather than
silently falling back to the shared cache. Ignored for pvc:// model
sources (already staged, read-only, no download). Node alignment of
RWO/local claims (via nodeSelector) is the user's responsibility.
minLength:
1maxLength:
253
modelRef
string required
ModelRef references the Model CR that contains the model to serve
moeCPULayers
integer
MoeCPULayers sets the number of MoE layers to offload to CPU.
When set, only the specified number of MoE layers run on CPU rather than all.
Maps to llama.cpp --n-cpu-moe flag.
format:
int32minimum:
0
moeCPUOffload
boolean
MoeCPUOffload offloads all MoE expert layers to CPU for reduced VRAM usage.
Enables running large MoE models (e.g., Qwen3-30B, Mixtral) on VRAM-constrained
hardware by keeping attention layers on GPU while expert weights use system RAM.
Maps to llama.cpp --cpu-moe flag. Requires sufficient system RAM via resources.memory.
noKvOffload
boolean
NoKvOffload keeps the KV cache in system RAM instead of VRAM.
Useful for extended context windows when VRAM is constrained by model weights.
Maps to llama.cpp --no-kv-offload flag. Requires sufficient system RAM via resources.memory.
noWarmup
boolean
NoWarmup skips the llama.cpp startup warmup inference pass.
Reduces pod ready time at the cost of slightly higher first-request latency.
Useful for scale-to-zero and quick redeployment patterns.
Maps to llama.cpp --no-warmup flag.
nodeSelector
object
NodeSelector for pod placement (e.g., specific node pools)
parallelSlots
integer
ParallelSlots sets the number of concurrent request slots for the llama.cpp
server (--parallel flag). Each slot processes one request independently;
higher values use more KV cache memory. If not specified, the operator
omits --parallel and llama.cpp picks an auto value (currently 4).
format:
int32minimum:
1maximum:
64personaPlexConfig object
PersonaPlexConfig holds configuration for the PersonaPlex (Moshi) runtime.
Only used when Runtime is "personaplex".
cpuOffload
boolean
CPUOffload enables model weight offloading to system RAM when GPU VRAM is insufficient.
Requires the accelerate package in the container image.
hfTokenSecretRef object
HFTokenSecretRef references a Secret containing the HuggingFace token for model download.
The Secret key must be "HF_TOKEN".
key
string required
The key of the secret to select from. Must be a valid secret key.
name
string
Name of the referent.
This field is effectively required, but due to backwards compatibility is
allowed to be empty. Instances of this type with an empty value here are
almost certainly wrong.
More info: https://kubernetes.io/docs/concepts/overview/working-with-objects/names/#names
optional
boolean
Specify whether the Secret or its key must be defined
quantize4Bit
boolean
Quantize4Bit enables NF4 4-bit quantization for reduced VRAM usage (~9.6 GB vs ~14 GB).
Requires the bitsandbytes package in the container image.
podAnnotations
object
PodAnnotations are merged into the inference Pod's metadata.annotations.
Use this to tag Pods for downstream tooling (cost attribution, service
mesh routing, custom admission controllers) without those tools needing
to know about LLMKube's CRD schema. Pure passthrough; the operator
itself does not set any annotations on inference Pods today.
podLabels
object
PodLabels are merged into the inference Pod's metadata.labels alongside
the operator-managed labels (`app`, `inference.llmkube.dev/model`,
`inference.llmkube.dev/service`). Operator-managed keys take precedence
on collision so the Deployment selector stays in sync with the Pods it
owns. The Deployment selector itself uses only the operator-managed
labels and is immutable, so changing PodLabels later is safe.
podSecurityContext object
PodSecurityContext defines pod-level security attributes for inference pods.
Use this to set fsGroup for volume permissions (required on OpenShift).
appArmorProfile object
appArmorProfile is the AppArmor options to use by the containers in this pod.
Note that this field cannot be set when spec.os.name is windows.
localhostProfile
string
localhostProfile indicates a profile loaded on the node that should be used.
The profile must be preconfigured on the node to work.
Must match the loaded name of the profile.
Must be set if and only if type is "Localhost".
type
string required
type indicates which kind of AppArmor profile will be applied.
Valid options are:
Localhost - a profile pre-loaded on the node.
RuntimeDefault - the container runtime's default profile.
Unconfined - no AppArmor enforcement.
fsGroup
integer
A special supplemental group that applies to all containers in a pod.
Some volume types allow the Kubelet to change the ownership of that volume
to be owned by the pod:
1. The owning GID will be the FSGroup
2. The setgid bit is set (new files created in the volume will be owned by FSGroup)
3. The permission bits are OR'd with rw-rw----
If unset, the Kubelet will not modify the ownership and permissions of any volume.
Note that this field cannot be set when spec.os.name is windows.
format:
int64
fsGroupChangePolicy
string
fsGroupChangePolicy defines behavior of changing ownership and permission of the volume
before being exposed inside Pod. This field will only apply to
volume types which support fsGroup based ownership(and permissions).

for that container.
Note that this field cannot be set when spec.os.name is windows.
format:
int64
runAsNonRoot
boolean
Indicates that the container must run as a non-root user.
If true, the Kubelet will validate the image at runtime to ensure that it
does not run as UID 0 (root) and fail to start the container if it does.
If unset or false, no such validation will be performed.
May also be set in SecurityContext. If set in both SecurityContext and
PodSecurityContext, the value specified in SecurityContext takes precedence.
runAsUser
integer
The UID to run the entrypoint of the container process.
Defaults to user specified in image metadata if unspecified.
May also be set in SecurityContext. If set in both SecurityContext and
PodSecurityContext, the value specified in SecurityContext takes precedence
for that container.
Note that this field cannot be set when spec.os.name is windows.
format:
int64
seLinuxChangePolicy
string
seLinuxChangePolicy defines how the container's SELinux label is applied to all volumes used by the Pod.
It has no effect on nodes that do not support SELinux or to volumes does not support SELinux.
Valid values are "MountOption" and "Recursive".
"Recursive" means relabeling of all files on all Pod volumes by the container runtime.
This may be slow for large volumes, but allows mixing privileged and unprivileged Pods sharing the same volume on the same node.
"MountOption" mounts all eligible Pod volumes with `-o context` mount option.
This requires all Pods that share the same volume to use the same SELinux label.
It is not possible to share the same volume among privileged and unprivileged Pods.
Eligible volumes are in-tree FibreChannel and iSCSI volumes, and all CSI volumes
whose CSI driver announces SELinux support by setting spec.seLinuxMount: true in their
CSIDriver instance. Other volumes are always re-labelled recursively.
"MountOption" value is allowed only when SELinuxMount feature gate is enabled.
If not specified and SELinuxMount feature gate is enabled, "MountOption" is used.
If not specified and SELinuxMount feature gate is disabled, "MountOption" is used for ReadWriteOncePod volumes
and "Recursive" for all other volumes.
This field affects only Pods that have SELinux label set, either in PodSecurityContext or in SecurityContext of all containers.
All Pods that use the same volume should use the same seLinuxChangePolicy, otherwise some pods can get stuck in ContainerCreating state.
Note that this field cannot be set when spec.os.name is windows.
seLinuxOptions object
The SELinux context to be applied to all containers.
If unspecified, the container runtime will allocate a random SELinux context for each
container. May also be set in SecurityContext. If set in
both SecurityContext and PodSecurityContext, the value specified in SecurityContext
takes precedence for that container.
Note that this field cannot be set when spec.os.name is windows.
level
string

seccompProfile object
The seccomp options to use by the containers in this pod.
Note that this field cannot be set when spec.os.name is windows.
localhostProfile
string
localhostProfile indicates a profile defined in a file on the node should be used.
The profile must be preconfigured on the node to work.
Must be a descending path, relative to the kubelet's configured seccomp profile location.
Must be set if type is "Localhost". Must NOT be set for any other type.
type
string required
type indicates which kind of seccomp profile will be applied.
Valid options are:
Localhost - a profile defined in a file on the node should be used.
RuntimeDefault - the container runtime default profile should be used.
Unconfined - no profile should be applied.
supplementalGroups
[]integer
A list of groups applied to the first process run in each container, in
addition to the container's primary GID and fsGroup (if specified). If
the SupplementalGroupsPolicy feature is enabled, the
supplementalGroupsPolicy field determines whether these are in addition
to or instead of any group memberships defined in the container image.
If unspecified, no additional groups are added, though group memberships
defined in the container image may still be used, depending on the
supplementalGroupsPolicy field.
Note that this field cannot be set when spec.os.name is windows.
supplementalGroupsPolicy
string
Defines how supplemental groups of the first container processes are calculated.
Valid values are "Merge" and "Strict". If not specified, "Merge" is used.
(Alpha) Using the field requires the SupplementalGroupsPolicy feature gate to be enabled
and the container runtime must implement support for this feature.
Note that this field cannot be set when spec.os.name is windows.
sysctls []object
Sysctls hold a list of namespaced sysctls used for the pod. Pods with unsupported
sysctls (by the container runtime) might fail to launch.
Note that this field cannot be set when spec.os.name is windows.
name
string required
Name of a property to set
value
string required
Value of a property to set
windowsOptions object
The Windows specific settings applied to all containers.
If unspecified, the options within a container's SecurityContext will be used.
If set in both SecurityContext and PodSecurityContext, the value specified in SecurityContext takes precedence.
Note that this field cannot be set when spec.os.name is linux.
gmsaCredentialSpec
string
GMSACredentialSpec is where the GMSA admission webhook
(https://github.com/kubernetes-sigs/windows-gmsa) inlines the contents of the
GMSA credential spec named by the GMSACredentialSpecName field.

In addition, if HostProcess is true then HostNetwork must also be set to true.
runAsUserName
string
The UserName in Windows to run the entrypoint of the container process.
Defaults to the user specified in image metadata if unspecified.
May also be set in PodSecurityContext. If set in both SecurityContext and
PodSecurityContext, the value specified in SecurityContext takes precedence.

is true, the controller will check backend slot idleness before updating
the Deployment pod-template. Idle detection support by runtime:
- llama.cpp: native /slots endpoint (default)
- vLLM: Prometheus metrics scrape (vllm:num_requests_running)
- TGI: Prometheus metrics scrape (tgi_batch_current_size)
- SGLang: Prometheus metrics scrape (sglang:num_running_reqs)
- generic: optional AnnotationIdleEndpoint annotation for custom probe
force
boolean
Force bypasses the idle check and proceeds with the rollout immediately.
When true, WaitForIdle is ignored. Useful for emergency rollouts or when
slots are stuck in a non-idle state.
idleTimeoutSeconds
integer
IdleTimeoutSeconds is the maximum time to wait for slots to become idle before
proceeding with the rollout regardless of slot state. Defaults to 300 (5 minutes)
when omitted or set to 0.
minimum:
0
waitForIdle
boolean
WaitForIdle indicates whether to wait for all backend slots to report idle
before applying a Deployment pod-template update. When true, the controller
probes each replica and defers the rollout until all replicas are idle or the
idleTimeoutSeconds expires. Idle detection is runtime-specific: llama.cpp uses
/slots, vLLM/TGI/SGLang scrape Prometheus gauges, and generic runtimes may set
AnnotationIdleEndpoint for a custom HTTP probe. Runtimes without idle detection
support proceed immediately with ReasonIdleCheckUnsupported.
ropeScaling object
RopeScaling configures RoPE-based context extension so a model can be
served past its native trained context (e.g. 128K served at 256K via
YaRN). For the llamacpp runtime this maps to --rope-scaling /
--rope-scale / --yarn-orig-ctx. Prefer this over raw spec.extraArgs:
it is validated and discoverable via `kubectl explain`. If --rope-scaling
is also present in spec.extraArgs, extraArgs wins and this is skipped.
factor
string
Factor is the scale multiplier (--rope-scale), e.g. "2.0" to double the
native context. A string to avoid CRD float pitfalls; the runtime parses
it as a float. Optional.
pattern:
^[0-9]+(\.[0-9]+)?$
originalContext
integer
OriginalContext is the model's native training context length
(--yarn-orig-ctx), e.g. 131072 for a 128K model. Recommended with yarn.
format:
int32minimum:
128

runtimeClassName
string
RuntimeClassName selects a Kubernetes RuntimeClass for the inference Pod.
Most commonly set to "nvidia" on clusters where the NVIDIA Container
Runtime is not configured as the cluster default. Without it, GPU pods
schedule onto the GPU node but never get the device files bind-mounted,
and the container fails at runtime with "no CUDA-capable device is
detected". Maps directly to PodSpec.RuntimeClassName.
Most clusters running the NVIDIA GPU Operator with the default toolkit
env do not need this set; it is a safety hatch for clusters where the
runtime configuration is non-default.
securityContext object
SecurityContext defines container-level security attributes for the inference container.
allowPrivilegeEscalation
boolean
AllowPrivilegeEscalation controls whether a process can gain more
privileges than its parent process. This bool directly controls if

string
GMSACredentialSpec is where the GMSA admission webhook
(https://github.com/kubernetes-sigs/windows-gmsa) inlines the contents of the
GMSA credential spec named by the GMSACredentialSpecName field.
gmsaCredentialSpecName
string
GMSACredentialSpecName is the name of the GMSA credential spec to use.
hostProcess
boolean
HostProcess determines if a container should be run as a 'Host Process' container.
All of a Pod's containers must have the same effective HostProcess value
(it is not allowed to have a mix of HostProcess containers and non-HostProcess containers).
In addition, if HostProcess is true then HostNetwork must also be set to true.
runAsUserName

NOTE: at present this only sets the in-process SGLang `--dp` flag.
Multi-replica rendezvous (SGLang's --dist-init-addr + a stable
network identity per pod, e.g. headless service + StatefulSet) is
not yet wired into the InferenceService controller and is tracked
at https://github.com/defilantech/LLMKube/issues/1102. Setting
this on an InferenceService with replicas > 1 will leave each
replica starting as its own DP-1 group; operators wanting true
DP coordination should hold off on this flag until #1102 lands.

enum:
bitsandbytes, gptq, awq, eetqtolerations []object
Tolerations for pod scheduling (e.g., GPU taints, spot instances)
effect
string
Effect indicates the taint effect to match. Empty means match all taint effects.
When specified, allowed values are NoSchedule, PreferNoSchedule and NoExecute.
key
string
Key is the taint key that the toleration applies to. Empty means match all taint keys.
If the key is empty, operator must be Exists; this combination means to match all values and all keys.
operator
string
Operator represents a key's relationship to the value.
Valid operators are Exists, Equal, Lt, and Gt. Defaults to Equal.
Exists is equivalent to wildcard for value, so that a pod can
tolerate all taints of a particular category.
Lt and Gt perform numeric comparisons (requires feature gate TaintTolerationComparisonOperators).
tolerationSeconds
integer
TolerationSeconds represents the period of time the toleration (which must be
of effect NoExecute, otherwise this field is ignored) tolerates the taint. By default,
it is not set, which means tolerate the taint forever (do not evict). Zero and
negative values will be treated as 0 (evict immediately) by the system.
format:
int64
value
string
Value is the taint value the toleration matches to.
If the operator is Exists, the value should be empty, otherwise just a regular string.
topologySpreadConstraints []object
TopologySpreadConstraints control how inference Pods are spread across
topology domains (e.g. one model server per GPU node). Passthrough to the
Pod spec; combine with PodLabels so the constraint's labelSelector can
match sibling GPU workloads for a soft, cross-app spread.
labelSelector object
LabelSelector is used to find matching pods.
Pods that match this label selector are counted to determine the number of pods
in their corresponding topology domain.
matchExpressions []object
matchExpressions is a list of label selector requirements. The requirements are ANDed.
key
string required
key is the label key that the selector applies to.
operator
string required
operator represents a key's relationship to a set of values.
Valid operators are In, NotIn, Exists and DoesNotExist.
values
[]string
values is an array of string values. If the operator is In or NotIn,
the values array must be non-empty. If the operator is Exists or DoesNotExist,
the values array must be empty. This array is replaced during a strategic
merge patch.
matchLabels
object
matchLabels is a map of {key,value} pairs. A single {key,value} in the matchLabels
map is equivalent to an element of matchExpressions, whose key field is "key", the
operator is "In", and the values array contains only "value". The requirements are ANDed.
matchLabelKeys
[]string
MatchLabelKeys is a set of pod label keys to select the pods over which
spreading will be calculated. The keys are used to lookup values from the
incoming pod labels, those key-value labels are ANDed with labelSelector
to select the group of existing pods over which spreading will be calculated
for the incoming pod. The same key is forbidden to exist in both MatchLabelKeys and LabelSelector.
MatchLabelKeys cannot be set when LabelSelector isn't set.
Keys that don't exist in the incoming pod labels will
be ignored. A null or empty list means only match against labelSelector.
This is a beta field and requires the MatchLabelKeysInPodTopologySpread feature gate to be enabled (enabled by default).
maxSkew
integer required
MaxSkew describes the degree to which pods may be unevenly distributed.
When `whenUnsatisfiable=DoNotSchedule`, it is the maximum permitted difference
between the number of matching pods in the target topology and the global minimum.
The global minimum is the minimum number of matching pods in an eligible domain
or zero if the number of eligible domains is less than MinDomains.
For example, in a 3-zone cluster, MaxSkew is set to 1, and pods with the same
labelSelector spread as 2/2/1:
In this case, the global minimum is 1.
| zone1 | zone2 | zone3 |
| P P | P P | P |
- if MaxSkew is 1, incoming pod can only be scheduled to zone3 to become 2/2/2;
scheduling it onto zone1(zone2) would make the ActualSkew(3-1) on zone1(zone2)
violate MaxSkew(1).
- if MaxSkew is 2, incoming pod can be scheduled onto any zone.
When `whenUnsatisfiable=ScheduleAnyway`, it is used to give higher precedence
to topologies that satisfy it.
It's a required field. Default value is 1 and 0 is not allowed.
format:
int32
minDomains
integer
MinDomains indicates a minimum number of eligible domains.
When the number of eligible domains with matching topology keys is less than minDomains,
Pod Topology Spread treats "global minimum" as 0, and then the calculation of Skew is performed.
And when the number of eligible domains with matching topology keys equals or greater than minDomains,
this value has no effect on scheduling.
As a result, when the number of eligible domains is less than minDomains,
scheduler won't schedule more than maxSkew Pods to those domains.
If value is nil, the constraint behaves as if MinDomains is equal to 1.
Valid values are integers greater than 0.
When value is not nil, WhenUnsatisfiable must be DoNotSchedule.
For example, in a 3-zone cluster, MaxSkew is set to 2, MinDomains is set to 5 and pods with the same
labelSelector spread as 2/2/2:
| zone1 | zone2 | zone3 |
| P P | P P | P P |
The number of domains is less than 5(MinDomains), so "global minimum" is treated as 0.
In this situation, new pod with the same labelSelector cannot be scheduled,
because computed skew will be 3(3 - 0) if new Pod is scheduled to any of the three zones,
it will violate MaxSkew.
format:
int32
nodeAffinityPolicy
string
NodeAffinityPolicy indicates how we will treat Pod's nodeAffinity/nodeSelector
when calculating pod topology spread skew. Options are:
- Honor: only nodes matching nodeAffinity/nodeSelector are included in the calculations.
- Ignore: nodeAffinity/nodeSelector are ignored. All nodes are included in the calculations.
If this value is nil, the behavior is equivalent to the Honor policy.
nodeTaintsPolicy
string
NodeTaintsPolicy indicates how we will treat node taints when calculating
pod topology spread skew. Options are:
- Honor: nodes without taints, along with tainted nodes for which the incoming pod
has a toleration, are included.
- Ignore: node taints are ignored. All nodes are included.
If this value is nil, the behavior is equivalent to the Ignore policy.
topologyKey
string required
TopologyKey is the key of node labels. Nodes that have a label with this key
and identical values are considered to be in the same topology.
We consider each <key, value> as a "bucket", and try to put balanced number
of pods into each bucket.
We define a domain as a particular instance of a topology.
Also, we define an eligible domain as a domain whose nodes meet the requirements of
nodeAffinityPolicy and nodeTaintsPolicy.
e.g. If TopologyKey is "kubernetes.io/hostname", each Node is a domain of that topology.
And, if TopologyKey is "topology.kubernetes.io/zone", each zone is a domain of that topology.
It's a required field.
whenUnsatisfiable
string required
WhenUnsatisfiable indicates how to deal with a pod if it doesn't satisfy
the spread constraint.
- DoNotSchedule (default) tells the scheduler not to schedule it.
- ScheduleAnyway tells the scheduler to schedule the pod in any location,
but giving higher precedence to topologies that would help reduce the
skew.
A constraint is considered "Unsatisfiable" for an incoming pod
if and only if every possible node assignment for that pod would violate
"MaxSkew" on some topology.
For example, in a 3-zone cluster, MaxSkew is set to 1, and pods with the same
labelSelector spread as 3/1/1:
| zone1 | zone2 | zone3 |
| P P P | P | P |
If WhenUnsatisfiable is set to DoNotSchedule, incoming pod can only be scheduled
to zone2(zone3) to become 3/2/1(3/1/2) as ActualSkew(2-1) on zone2(zone3) satisfies
MaxSkew(1). In other words, the cluster can still be imbalanced, but scheduler
won't make it *more* imbalanced.
It's a required field.
turboQuantBits
integer
TurboQuantBits sets the KV cache quantization bit width for the oMLX
runtime (3, 6, or 8). Maps to oMLX --kv-cache-quant. When set, the
oMLX daemon uses TurboQuant to compress the KV cache, reducing memory
usage by up to 67% with minimal speed impact (~7% overhead). Only
meaningful for the omlx runtime; ignored by llamacpp and other runtimes.

cpuOffloadGB
integer
CPUOffloadGB increases the GPU memory size. When set, passes
--cpu-offload-gb to vLLM. Per-rank, so 4 on TP=2 means 4 GB of
CPU RAM per GPU. Use when FP8 model weights don't fit VRAM.
Throughput hit is 2-5x on the offloaded path.

dtype
string
Dtype sets the model data type (auto, float16, bfloat16).
enum:
auto, float16, bfloat16
enableChunkedPrefill
boolean
EnableChunkedPrefill interleaves long prefills with decode steps so a
large paste (e.g. a 32K-token file) does not starve concurrent decode
streams. Only emitted when explicitly set to true.
Maps to vLLM --enable-chunked-prefill flag.
enableExpertParallel
boolean
EnableExpertParallel distributes MoE experts across tensor-parallel ranks
instead of replicating them. Only meaningful for MoE models.
Maps to vLLM --enable-expert-parallel flag.
enablePrefixCaching
boolean
EnablePrefixCaching turns on vLLM's automatic prefix caching for repeated prompts.
Significantly reduces time-to-first-token for conversational and agentic workloads
where requests share a common system prompt.
Only emitted when explicitly set to true — when nil or false, vLLM's own
default is used (do not emit the flag).
Maps to vLLM --enable-prefix-caching flag.
gpuMemoryUtilization
number
GPUMemoryUtilization controls how much GPU memory each stage can use.
When set, passes --gpu-memory-utilization to vLLM. Range from 0.1 - 0.99
and default unset (vLLM uses 0.90).
minimum:
0.1maximum:
0.99hfTokenSecretRef object
HFTokenSecretRef references a Secret containing the HuggingFace token.
key
string required
The key of the secret to select from. Must be a valid secret key.
name
string
Name of the referent.
This field is effectively required, but due to backwards compatibility is
allowed to be empty. Instances of this type with an empty value here are
almost certainly wrong.
More info: https://kubernetes.io/docs/concepts/overview/working-with-objects/names/#names
optional
boolean
Specify whether the Secret or its key must be defined
kvCacheCustomDtype
string
KVCacheCustomDtype sets a custom vLLM KV cache element type that is not
in the standard enum. Used for vLLM versions with additional cache
formats such as TurboQuant 2-bit (turbo2, shipped in v0.20.0). Maps to
vLLM --kv-cache-dtype. The runtime image must understand the value or
vLLM will fail to start; LLMKube does not validate the string. Mirrors
the llama.cpp-side CacheTypeCustomK/V escape hatch.
Takes precedence over KVCacheDtype when both are set.
kvCacheDtype
string
KVCacheDtype selects the KV cache element type. fp8_e5m2 and fp8_e4m3 cut
KV cache memory roughly in half versus auto (which follows dtype), which
is what unlocks 128K+ context on consumer VRAM for agentic workloads.
Maps to vLLM --kv-cache-dtype flag.
For custom build types not in the enum (e.g. TurboQuant turbo2 from
vLLM v0.20+), use KVCacheCustomDtype instead.
enum:
auto, fp8_e5m2, fp8_e4m3
maxModelLen
integer
MaxModelLen sets the maximum model context length.
format:
int32
maxNumBatchedTokens
integer
MaxNumBatchedTokens sets the maximum number of tokens batched together
per step. This is the main throughput knob: too low means prefill-bound,
too high risks OOM on long context. No default — only emitted when set.
Maps to vLLM --max-num-batched-tokens flag.

int32minimum:
512
quantization
string
Quantization method.
awq, gptq, squeezellm are classic 4-bit formats. fp8 targets 8-bit FP
checkpoints (Qwen FP8, Llama FP8, etc.). nvfp4 is NVIDIA's Blackwell-native
4-bit format. compressed-tensors is the neuralmagic/vLLM cross-format
loader used by Unsloth and other recent releases.
enum:
awq, gptq, squeezellm, fp8, nvfp4, compressed-tensorsspeculative object
Speculative enables draft-model speculative decoding. On single-stream
agentic workloads this can be 30-60% faster than plain tensor-parallel
execution. Requires a second (smaller) Model CR to act as the draft.
enabled
boolean
Enabled toggles speculative decoding on. When false or nil, no
speculative flags are emitted regardless of other fields.
model
string
Model references the Model CR (in the same namespace as the
InferenceService) to use as the speculative draft model.
Required when Enabled is true. If missing, speculative decoding is
skipped and the InferenceService surfaces a SpeculativeInvalid
status condition rather than failing the reconcile.
Maps to vLLM --speculative-model flag.
numSpeculativeTokens
integer
NumSpeculativeTokens is the number of draft tokens proposed per step.
Typical sweet spot is 3-5; higher values increase wasted work when the
draft disagrees with the target model.
Maps to vLLM --num-speculative-tokens flag.

tensorParallelSize
integer
TensorParallelSize sets the number of GPUs for tensor parallelism.
format:
int32status object
status defines the observed state of InferenceService
conditions []object
conditions represent the current state of the InferenceService resource.
Each condition has a unique type and reflects the status of a specific aspect of the resource.
Standard condition types include:
- "Available": the resource is fully functional
- "Progressing": the resource is being created or updated
- "Degraded": the resource failed to reach or maintain its desired state
The status of each condition is one of True, False, or Unknown.
lastTransitionTime
string required
lastTransitionTime is the last time the condition transitioned from one status to another.
This should be when the underlying condition changed. If that is not known, then using the time when the API field changed is acceptable.
format:
date-time
message
string required
message is a human readable message indicating details about the transition.
This may be an empty string.
maxLength:
32768
observedGeneration
integer
observedGeneration represents the .metadata.generation that the condition was set based upon.
For instance, if .metadata.generation is currently 12, but the .status.conditions[x].observedGeneration is 9, the condition is out of date
with respect to the current state of the instance.
format:
int64minimum:

reason
string required
reason contains a programmatic identifier indicating the reason for the condition's last transition.
Producers of specific condition types may define expected values and meanings for this field,
and whether the values are considered a guaranteed API.
The value should be a CamelCase string.
This field may not be empty.

effectivePriority
integer
EffectivePriority shows the resolved priority value from the applied PriorityClass
format:
int32
endpoint
string
Endpoint is the service URL where inference requests can be sent
gateway object
Gateway reports the result of Envoy AI Gateway exposure for this
InferenceService. Populated only when spec.endpoint.gateway is enabled.
nil means no gateway exposure was requested (or the gateway integration
is disabled because the aigw CRDs are not installed; that case is also
surfaced via the GatewayReady condition).
authEnabled
boolean
AuthEnabled indicates a SecurityPolicy enforcing JWT authentication was
compiled for this route (ModelRouter policy.auth.jwt). Set by the
ModelRouter dataPlane: Gateway path; false when no auth is configured.
endpoint
string
Endpoint is the gateway address clients send OpenAI requests to. Set by
the ModelRouter dataPlane: Gateway path (resolved from the referenced
Gateway); empty for the InferenceService path.
modelName
string
ModelName is the resolved model-name match value clients send as the
OpenAI "model" string to reach this InferenceService through the gateway.
Set by the InferenceService path; empty for ModelRouter (which fronts
many model names).
routeReady
boolean
RouteReady indicates the AIGatewayRoute (and its backing Backend +
AIServiceBackend) were reconciled successfully against the gateway.
lastUpdated
string
LastUpdated is the timestamp of the last status update
format:
date-time
mode
string
Mode is the resolved serving mode (chat, embedding, or rerank): spec.mode
when set, otherwise inferred from the runtime flags and endpoint path.
modelReady
boolean
ModelReady indicates if the referenced Model is in Ready state
phase
string
Phase represents the current lifecycle phase of the InferenceService.
Possible values: Pending, Creating, Progressing, Ready, WaitingForGPU,
Stopped, Failed. Stopped is the terminal state when spec.replicas=0
has caused the agent to tear down the workload; tooling polling for
readiness should treat Stopped the same as Pending (the user
intentionally took the service offline; this is not an error).
enum:
Pending, Creating, Progressing, Ready, WaitingForGPU, Stopped, Failed
queuePosition
integer
QueuePosition indicates position among pending InferenceServices cluster-wide (0 = not queued)
format:

Replicas is the current number of running inference pods
format:
int32
schedulingMessage
string
SchedulingMessage provides details about scheduling issues
schedulingStatus
string
SchedulingStatus indicates why pods cannot be scheduled (e.g., "InsufficientGPU")
waitingFor
string
WaitingFor describes the resource constraint (e.g., "nvidia.com/gpu: 1")
No matches. Try .spec.affinity for an exact path
