Values reference

Helm checks these against the chart’s values.schema.json on every install and upgrade, so a misspelled key or a wrong type stops the install. To see them from the chart itself, run helm show values oci://ghcr.io/paulbouwer/charts/hello-kubernetes. For the values most people change, the config builder writes the command or the file for you.

Value	Type	Default	Description
message	string	""	A message to show instead of Hello world!. It must be a string: quote it in a values file, or use --set-string.
pathPrefix	string	""	Serve the app under a path prefix, such as /app/hello, behind an Ingress, an HTTPRoute or your own proxy. Leading and trailing slashes are optional.
rewritePath	bool	true	false (recommended): the proxy passes the prefix on, and the app serves under it. true: the proxy strips the prefix, and the app serves at /. See path prefixes and rewriting.
ingress.enabled	bool	false	Create a networking.k8s.io/v1 Ingress for pathPrefix.
ingress.className	string	""	The Ingress class, such as nginx or traefik. Empty uses the cluster’s default class.
ingress.annotations	object	{}	Annotations for the Ingress, such as your controller’s rewrite annotation when rewritePath is true.
ingress.host	string	""	The host name for the Ingress rule. Empty matches all hosts, but the NGINX Ingress Controller needs a host.
ingress.tls	list	[]	The Ingress TLS settings, as in the Ingress spec.tls field.
httpRoute.enabled	bool	false	Create a Gateway API HTTPRoute for pathPrefix. With rewritePath true, it strips the prefix with the standard URLRewrite filter.
httpRoute.parentRefs	list	[]	The Gateways to attach to. Required when httpRoute.enabled is true.
httpRoute.hostnames	list	[]	The host names for the route. Empty matches the Gateway’s host names.
service.type	string	LoadBalancer	ClusterIP, NodePort or LoadBalancer. Use ClusterIP behind an Ingress or a Gateway.
service.port	int	80	The port the Service exposes.
deployment.replicaCount	int	2	The number of pods.
deployment.container.image.repository	string	paulbouwer/hello-kubernetes	The image, such as ghcr.io/paulbouwer/hello-kubernetes.
deployment.container.image.tag	string or number	""	The image tag, such as 1, 1.11 or 1.11.0. Empty uses the chart’s appVersion. In a values file, quote it: YAML reads 1.10 as the number 1.1.
deployment.container.image.pullPolicy	string	IfNotPresent	Always, IfNotPresent or Never.
deployment.container.port	int	8080	The port the app listens on. The probes and the Service follow it.
deployment.container.securityContext	object	no privilege escalation, all capabilities dropped, read-only root filesystem	The container security context. With deployment.podSecurityContext, it meets the restricted Pod Security Standard.
deployment.podSecurityContext	object	runAsNonRoot, user and group 1000, RuntimeDefault seccomp	The pod security context.
deployment.nodeSelector	object	kubernetes.io/os: linux	The node selector. The image runs on amd64 and arm64 nodes.
deployment.resources	object	{}	The container resource requests and limits.
deployment.tolerations	list	[]	The pod tolerations.
deployment.affinity	object	{}	The pod affinity.
ingress.configured, ingress.pathPrefix, ingress.rewritePath			Deprecated. They still work in 1.x, and the install notes list them. Use pathPrefix and rewritePath. They are removed in 2.0.
