Quest for syntax highlighting in Argo CD ApplicationSet helm chart values overrides

[jessebot]

Argo CD offers quite a few ways to override values from a helm chart. None of them allow you to template values and maintain syntax highlighting on large values.yaml files right now, but we are very hopeful! This Issue exists to track all the issues and pull requests and docs that I think might help us move forward here.

Issues

• ApplicationSets cannot template generator values within remote repo values.yaml override when using multiple sources argoproj/argo-cd#16455

• bug: ApplicationSet Controller CrashLoopBackoff when using helm.valuesObject and list generator argoproj/argo-cd#14912

• Application set templating fails with arrays (Helm valueFiles) argoproj/argo-cd#9583

Pull Requests

We are now free of this issue thanks to this comment:
argoproj/argo-cd#14912 (comment)

The gist is we need to single quote our templated values :) that's it. we can use valuesObject again!!
