Is your feature request related to a problem? Please describe.

Somewhat related to #437, it would be very helpful to have the ability to set environment variables from secrets.

Describe the solution you'd like

it would be nice to either specifying literals for environment variables, or being able to use the config map ref or secret ref, pretty much like that:

name: CODER_OIDC_CLIENT_SECRET
valueFrom:
  secretKeyRef:
    name: secretname
    key: oidc_secret

Describe alternatives you've considered

This is supported by the upstream common library. Here's how you could set your example env:

env:
  CODER_OIDC_CLIENT_SECRET:
    valueFrom:
      secretKeyRef:
        name: secretname
        key: oidc_secret

Awesome, thanks! Would it be helpful to include an example in the default values.yaml? This is usually where I'm looking

@waza-ari You're welcome! That definitely wouldn't hurt. Feel free to make a PR if you'd like. Otherwise, I can add an example next time I work on the paperless-ngx chart.

@waza-ari Did you ever end up resolving this? :)

@jimkoen Secrets are fully supported! See #573 (comment) for an example.
