Sending basePath to yamls renderer

[anih]

Hi,

I would like to propose this change because we faced a problem when we have app X that depends on app Y and we wanted to put Y in X dependencies:

helmfiles:
  - path: git::https://github/anih/Y.git@helmfile/helmfile.yaml?ref=master

But in Y we have

helmfiles:
  - path: git::https://github/anih/generic-app.git@helmfile/helmfile.yaml?ref=master
    values:
      - extraValuesTemplates:
        - {{ requiredEnv "PWD" }}/values/values-file.yaml.gotmpl

unfortunately after removing {{ requiredEnv "PWD" }} i was getting error like

values file matching "/project/.helmfile/cache/https_gihub_generic-app_git.ref=master/generic-api/values/values-file.yaml.gotmpl" does not exist in "/project/.helmfile/cache/https_gihub_generic-app_git.ref=master/generic-api"

With this patch all is working correctly.

@anih Hey! I Thanks a lot for the PR.

I finally took some time to read this.

Just to confirm, is this change basically adds two things to helmfile?

• A template function called basePath to obtain the absolute path to the directory of the helmfile.yaml being processed
• Change the helmfile internal to use absolute pathes to locate files, so that the basePath becomes absolute one, where it was formerly relative

Hi,
Thank you for looking into it. Yes it's adding what you wrote. Probably rendering values from file it's done too late and path for values/values-file.yaml.gotmpl is taken from helmfile fro app X instead of Y app where this values file was added.
