@aabouzaid Thanks for fixing the PR! The introduced vars are needed for a feature for console self-managed: byo oidc. Would be great if you can review it.

Any reason to wrap the plain vars in the named templates?
If not, let's use them directly in the configmap.yaml

@aabouzaid Not sure what you mean ;) I just need the vars in the configmap.

If you could make the adjustments I'd be more than happy.

@urbanisierung my question about doing this:

clientId: {{ include "console.authClientId" . | quote }}

not this:

clientId: {{- .Values.global.identity.auth.console.clientId | quote -}}

the point here, it's working like a var, but used in 1 place only.
do you have any plans to use it in different places or extend the logic?
