Looks good! You'll need to re-gen the chart readme and bump the chart version

Sure, will do, also verify, I'm suspicious of how helm would deal with the declaimer header, then the if, Usually the if would be the top level 'item'.

I'll test that as well

seems legit 👍

Locally against my PR branch with default values (explicit default for new parameter)

[root@LAPTOP-ASAF-T14 superset]# helm template . --set secretEnv.create=true -s templates/secret-env.yaml --debug
install.go:218: [debug] Original chart version: ""
install.go:235: [debug] CHART PATH: /opt/gits/superset/helm/superset

# Source: superset/templates/secret-env.yaml
apiVersion: v1
kind: Secret

  namespace: default
  labels:
    app: release-name-superset
    chart: superset-0.12.9

    DB_PORT: "5432"
    DB_USER: "superset"
    DB_PASS: "superset"
    DB_NAME: "superset"

And now with the new parameter as false:

[root@LAPTOP-ASAF-T14 superset]# helm template . --set secretEnv.create=false -s templates/secret-env.yaml --debug
install.go:218: [debug] Original chart version: ""
install.go:235: [debug] CHART PATH: /opt/gits/superset/helm/superset

Error: could not find template templates/secret-env.yaml in chart
helm.go:84: [debug] could not find template templates/secret-env.yaml in chart

Just for future reference and search indexing, For those using ArgoCD with the old versions of superset's helm chart and wish to use external secrets, I have had limited success with ignoreDifferences:

    - kind: "Secret"
