[ISSUE] Unable to reference existingSecret for camunda components

[proxyvert]

Describe the issue:

When I try to utilize existingSecret for camunda components, it still generates default secret and puts value of global.identity.auth.camunda-component.existingSecret in camunda-component secretKey base64 encoded, instead of referencing existingSecret that I created.

snippet from values.yaml:

global:
  identity:
    auth:
      enabled: true
      publicIssuerUrl: https://mykeycloak.example.com/auth/realms/myrealm
      connectors:
        existingSecret: myExistingSecretName

Actual behavior:

camunda-platform/charts/identity/templates/deployment.yaml env is using default secret that is created by chart:

          - name: KEYCLOAK_CLIENTS_0_SECRET
            valueFrom:
              secretKeyRef:
                key: connectors-secret
                name: "dev-connectors-identity-secret"

camunda-platform/charts/identity/templates/connectors-secret.yaml is rendered to:

apiVersion: v1
kind: Secret
metadata:
  name: "dev-connectors-identity-secret"
  labels:
    app: camunda-platform
    app.kubernetes.io/name: identity
    app.kubernetes.io/instance: dev
    app.kubernetes.io/managed-by: Helm
    app.kubernetes.io/part-of: camunda-platform
    helm.sh/chart: identity-8.2.6
    app.kubernetes.io/version: "8.3.0-alpha2"
    app.kubernetes.io/component: identity
type: Opaque
data:
  connectors-secret: "base64encoded myExistingSecretName"

Expected behavior:

camunda-platform/charts/identity/templates/deployment.yaml env is using myExistingSecret that is created by me that has right secretKey in place:

          - name: KEYCLOAK_CLIENTS_0_SECRET
            valueFrom:
              secretKeyRef:
                key: connectors-secret
                name: "myExistingSecretName"

How to reproduce:

create myExistingSecret that has connectors-secret secretKey and arbitrary value.

use values.yaml and run helm template

global:
  identity:
    auth:
      enabled: true
      publicIssuerUrl: https://mykeycloak.example.com/auth/realms/myrealm
      connectors:
        existingSecret: myExistingSecretName

Steps to reproduce the issue.

If possible add a minimal reproducer code sample in a new repo/branch.

We have the same issue and currently try to reverse engineer the Helm chart. Do you know any workaround?

[floric]

@PaleIntrovert We found the solution in other issues :)

You need to use:

global:
  identity:
    auth:
      connectors:
        existingSecret:
          name: myExistingSecretName

@floric, I'm very grateful for you help, I checked this structure of values and rendered templates are indeed referencing existingSecret.
