Support GitHub Pages Index Path other than repository root

[caleblloyd]

The index.yaml on the GitHub Pages branch is currently hardcoded to the repository root:

chart-releaser/pkg/releaser/releaser.go

Line 114 in a5166bb

indexYamlPath := filepath.Join(worktree, "index.yaml")

It is possible that the file is served from a path, for example:

https://org.github.io/repo/helm/charts/

I propose to add an option to the index command to make the pages-index-path configurable

sounds good to me

Why not just respect index-path ? I set index-path to website/helm/index.yaml thinking it would be pushed to that location as well but got the behavior you describe which doesn't make sense to me. In my case the file gets created as it doesn't exists but if you store it in the source code I get why you would need a different variable for that. It's just counter-intuitive when this file is not stored in the source code but only pushed to gh-pages

This was confusing to me as well, but upon looking into the source code It looks like index-path is the current working index file on the current branch. It doesn't even have to point to an existing file; the most up-to-date index file can be downloaded by passing the --charts-repo option to cr index

Since GitHub pages branches are often orphan branches with different directory structures, the index-path and pages-index-path could be different.

To make the index-path option work, operations on it should be performed on the pages-branch and not the current branch. I could work up a PR for this if that is the preferred behavior

@cpanato when can we expect a new release in order to use that new feature with chart-releaser-action ?
