Helmfile: Comments are parsed

[tonsV2]

Applying the below chart results in an error.

Chart...

repositories:
  - name: chartmuseum
    url: https://chartmuseum.fitfit.dk

releases:
  - name: whoami
    namespace: whoami
    chart: chartmuseum/whoami-release
#    chart: chartmuseum/whoami-{{ requiredEnv "STAGE" }}

helmDefaults:
  recreatePods: true
  force: true

Command and error...

$ helm tiller run helmfile -f whoami.yaml apply
Installed Helm version v2.12.1
Installed Tiller version v2.12.1
Helm and Tiller are the same version!
Starting Tiller...
Tiller namespace: kube-system
Running: helmfile -f whoami.yaml apply

error during whoami.yaml parsing: template: stringTemplate:9:34: executing "stringTemplate" at <requiredEnv "STAGE">: error calling requiredEnv: required env var `STAGE` is not set
Stopping Tiller...
Error: plugin "tiller" exited with error

I'm thinking that since the requiredEnv function (?) is within a comment it should be ignored.

@tonsV2 Hey! Thanks for reporting.

Unfortunately, this can't be fixed.

Your whoami.yaml is basically a golang text/template, which is firstly executed to produce a YAML data. If we reverse the ordering, many of the helmfile yaml files fail due to that a template file isn't usually a valid YAML file.

If you just a whatever way to comment things out, {{* .... *}} can be used instead.

Thanks for pointing out an alternative solution

@tonsV2 Thanks for checking-in! Hope it helps. Please feel free to leave any comment in case something went wrong!

That asterisk commenting does not work:

error during helmfile.yaml parsing: template: stringTemplate:51: unexpected "*" in command

@Morriz Sry I misread the golang text/template doc, but it seems like you should use {{/* whatever */}} instead
