provide special flags to environment for certain stages

[Morriz]

I would like to be able to infer that a chart is beying installed or destroyed, so that I can make better use of exec.

Scenario:

Some apps in the wild don't support helm or not fully (knative, cert-manager etc), but I would like to use helmfile ordering to install their manifests at the right time.

So I create a basic deploy script that either does a k apply -f $FOLDER, or, and that is about my request, it does a k delete -f $FOLDER.

And I can't use raw directly, as it's unfeasible to dissect the manifests and massage them into the supported format by raw.

@Morriz Hey! It's still rough around the edges but I believe you can benefit from #673.

With it, you should be able to specify a directory containing k8s manifests in chart, like chart: ./manifests so that helm-x magically determines it as a k8s manifests and automatically turns it into a helm chart.

We don't need differentiation between apply/delete. Just run helmfile destroy/delete to delete everything, or set installed: false as similar as a release based on a regular chart to uninstall the specific release.

[Morriz]

Wow, that would be an elaborate solution...awesome!

[Morriz]

Would it also know how to escape {{ and }} in embedded templates? Like in grafana dashboard json?

[mumoshu]

@Morriz Are you trying to escape {{ and }} in helmfile.yaml and values.yaml.gotmpl files?

Then try:

{{`

and

`}}

like

{{`{{ .foo.bar }}`}}

This renders to a text of {{ .foo.bar }}.

[mumoshu]

Ah sry I misunderstood your question.
helm-x doesn't process any template expression seen in files under chart: ./yourmanifests or chart: ./yourkustomization. So it doesn't need to know about escaping.

[Morriz]

Ah, great. Than I can ditch my custom skeleton app solution...will try soon
