Helm - Check if value not exists OR part of list

Assuming I have this values.yaml under my helm chart -

tasks:
  - name: test-production-dev
    env:
      - production
      - dev
  - name: test-dev
    env:
      - dev
  - name: test-all

environment_variables:
  STAGE: dev

I would like to run my cronjob based on these values -

  • if .env doesn't exist - run any time.
  • if .env exists - run only if environment_variables.STAGE is in the .env list.

This is what I've done so far ( with no luck ) -

{{- range $.Values.tasks}}
# check if $value.env not exists OR contains stage
{{if or .env (hasKey .env "$.Values.environment_variables.STAGE")  }}
apiVersion: batch/v1
kind: CronJob
...
{{- end}}
---
{{- end}}
