Helmfile resolves relative paths incorrectly if PWD is a softlink

[reegnz]

Operating system

MacOS Ventura 13.5.2

Helmfile Version

0.157.0

Helm Version

3.12.3

Bug description

When using relative paths (eg. path: ../../helmfile.yaml) in helmfile.yaml, the relative path should always be resolved to the absolute path, with symlinks being resolved. Otherwise the behaviour of helmfile breaks:

• helmfile behaves differently if the directory it is softlinked and invoked when cd-ing into the softlink.

When you ignore softlinks (eg. resolve them always), the problem just goes away and has a reasonable default behaviour: always picking up relative paths from the real paths, not softlinked ones.

Example helmfile.yaml

See example repo.

Error message you've seen (if any)

❯ helmfile template
in ./helmfile.yaml: in .helmfiles[0]: in ../../helmfile.yaml: open helmfile.yaml: no such file or directory

I'm preparing a PR to fix this.

BTW tools like direnv deal with this problem really gracefully already.

@reegnz good catch.
