Kubernetes - Set Release.Namespace to dependencies values on values.yaml

I know there are many questions around this but I didn't find any with a real answer.

My helm chart have dependencies from another helm charts and I need to override their values with my .Release.Name and .Release.Namespace.

My requeriments.yaml

dependencies:
- name: keycloak
  alias: keycloak-config
  repository: https://my-repository.com/
  version: 1.0.0
- name: kong
  alias: kong-config
  repository: https://my-repository.com/
  version: 1.0.0

On my values.yaml

kong-config:
  websso:
    service:
      fullnameOverride: "my-helm._RELEASE_NAMESPACE_.svc.cluster.local"
      ckngOauth2Opts: "--data config.post_logout_redirect_uri=/_RELEASE_NAME_
                       --data config.logout_path=/_RELEASE_NAME_/logout"

I basically need to use {{ .Release.Name }} where I have _RELEASE_NAME_ and {{ .Release.Namespace }} where I have _RELEASE_NAMESPACE_.

I already tried:

  • {{ .Release.Name }} and {{ .Release.Namespace }}
  • $RELEASE_NAME and $RELEASE_NAMESPACE
  • ${RELEASE_NAME} and ${RELEASE_NAMESPACE}

but nothing works.

Note I really need to access those values at values.yaml. I don't have access to my dependencies code to change and set that values on that.

How can I solve this?

Solution

  • I solved this executing one additional command outside of my helm chart. As I have a Makefile file for my project build process where I can run some scripts for the multiple stages of my build. And so I added this command to the deploy stage:

    sed -i "s/_RELEASE_NAMESPACE_/$(NAMESPACE)/g" $(MODULE_PATH)/chart/values.yaml

    This works for a build workflow in some tool. But when I want to install manually my helm chart somewhere, it can't be done and I need to change manually that value with the server value.
