kgateway

A Helm chart for the kgateway project

Values

Key	Type	Description
affinity	object	Set affinity rules for pod scheduling, such as ’nodeAffinity:'.
agentgateway	object	Enable the integration with Agent Gateway, which lets you use kgateway to help manage agent connectivity across MCP servers, A2A agents, and REST APIs.
controller	object	Configure the kgateway control plane deployment.
controller.extraEnv	object	Add extra environment variables to the controller container.
controller.image	object	Configure the controller container image.
controller.image.pullPolicy	string	Set the image pull policy for the controller.
controller.image.registry	string	Set the image registry for the controller.
controller.image.repository	string	Set the image repository for the controller.
controller.image.tag	string	Set the image tag for the controller.
controller.logLevel	string	Set the log level for the controller.
controller.replicaCount	int	Set the number of controller pod replicas.
controller.service	object	Configure the controller service.
controller.service.ports	object	Set the service ports for gRPC and health endpoints.
controller.service.type	string	Set the service type for the controller.
controller.strategy	object	Change the rollout strategy from the Kubernetes default of a RollingUpdate with 25% maxUnavailable, 25% maxSurge. E.g., to recreate pods, minimizing resources for the rollout but causing downtime: strategy: type: Recreate E.g., to roll out as a RollingUpdate but with non-default parameters: strategy: type: RollingUpdate rollingUpdate: maxSurge: 100%
controller.xds	object	Configure TLS settings for the xDS gRPC servers.
controller.xds.tls.enabled	bool	Enable TLS encryption for xDS communication. When enabled, both the main xDS server (port 9977) and agent gateway xDS server (port 9978) will use TLS. When TLS is enabled, you must create a Secret named ‘kgateway-xds-cert’ in the kgateway installation namespace. The Secret must be of type ‘kubernetes.io/tls’ with ’tls.crt’, ’tls.key’, and ‘ca.crt’ data fields present.
deploymentAnnotations	object	Add annotations to the kgateway deployment.
discoveryNamespaceSelectors	list	List of namespace selectors (OR’ed): each entry can use ‘matchLabels’ or ‘matchExpressions’ (AND’ed within each entry if used together). Kgateway includes the selected namespaces in config discovery. For more information, see the docs https://kgateway.dev/docs/operations/install/#namespace-discovery.
fullnameOverride	string	Override the full name of resources created by the Helm chart, which is ‘kgateway’. If you set ‘fullnameOverride: “foo”, the full name of the resources that the Helm release creates become ‘foo’, such as the deployment, service, and service account for the kgateway control plane in the kgateway-system namespace.
image	object	Configure the default container image for the components that Helm deploys. You can override these settings for each particular component in that component’s section, such as ‘controller.image’ for the kgateway control plane. If you use your own private registry, make sure to include the imagePullSecrets.
image.pullPolicy	string	Set the default image pull policy.
image.registry	string	Set the default image registry.
image.tag	string	Set the default image tag.
imagePullSecrets	list	Set a list of image pull secrets for Kubernetes to use when pulling container images from your own private registry instead of the default kgateway registry.
inferenceExtension	object	Configure the integration with the Gateway API Inference Extension project, which lets you use kgateway to route to AI inference workloads like LLMs that run locally in your Kubernetes cluster. Documentation for Inference Extension can be found here: https://kgateway.dev/docs/integrations/inference-extension/
inferenceExtension.autoProvision	bool	Enable automatic provisioning for Inference Extension. Deprecated: this is deprecated in v2.1 and will be removed in v2.2.
inferenceExtension.enabled	bool	Enable Inference Extension. If enabled, agentgateway.enabled should also be set to true. Enabling inference extension without agentgateway is deprecated in v2.1 and will not be supported in v2.2.
nameOverride	string	Add a name to the default Helm base release, which is ‘kgateway’. If you set ’nameOverride: “foo”, the name of the resources that the Helm release creates become ‘kgateway-foo’, such as the deployment, service, and service account for the kgateway control plane in the kgateway-system namespace.
nodeSelector	object	Set node selector labels for pod scheduling, such as ‘kubernetes.io/arch: amd64’.
podAnnotations	object	Add annotations to the kgateway pods.
podSecurityContext	object	Set the pod-level security context. For example, ‘fsGroup: 2000’ sets the filesystem group to 2000.
policyMerge	object	Policy merging settings. Currently, TrafficPolicy’s extAuth, extProc, and transformation policies support deep merging. E.g., to enable deep merging of extProc policy in TrafficPolicy: policyMerge: trafficPolicy: extProc: DeepMerge
resources	object	Configure resource requests and limits for the container, such as ’limits.cpu: 100m’ or ‘requests.memory: 128Mi’.
securityContext	object	Set the container-level security context, such as ‘runAsNonRoot: true’.
serviceAccount	object	Configure the service account for the deployment.
serviceAccount.annotations	object	Add annotations to the service account.
serviceAccount.create	bool	Specify whether a service account should be created.
serviceAccount.name	string	Set the name of the service account to use. If not set and create is true, a name is generated using the fullname template.
tolerations	list	Set tolerations for pod scheduling, such as ‘key: “nvidia.com/gpu”’.
validation	object	Configure validation behavior for route and policy safety checks in the control plane. This setting determines how invalid configuration is handled to prevent security bypasses and to maintain multi-tenant isolation.
validation.level	string	Validation level. Accepted values: “standard” or “strict” (case-insensitive). Standard replaces invalid routes with a direct 500 response and continues applying valid configuration. Strict adds xDS preflight validation and blocks snapshots that would NACK in Envoy. Default is “standard”.
waypoint	object	Enable the waypoint integration. This enables kgateway to translate istio waypoints and use kgateway as a waypoint in an Istio Ambient service mesh setup..
