Root folder in `chart_path` leads to git repo in git repo

[Zaunei]

While using git repos for helm charts works great for charts that are in subfolders, it becomes impractical once the helm chart is in the root folder.

In a Monrepo approach for GitOps, there is then a git repo in a git repo, which makes checking in the files difficult.

Example:

charts:
  - name: netbox
    repo_name: bootc-netbox-git
    chart_path: /
    version: 9f537a99928d42f9f1854e95c605db8bc352d4c8
repos:
  - name: stable
    url: https://charts.helm.sh/stable
  - name: bootc-netbox-git
    type: git
    url: https://github.com/bootc/netbox-chart.git
destinations:
  - name: default
    path: ./foobar

Maybe it makes sense here to add an option to delete the .git folder after checkout?

Hello @Zaunei! I like that idea 😉

Maybe one could use the Skip option when copying the cloned files from the temp directory to the configured destination:

helm-freeze/exec/helm.go

Line 226 in 9c2d068

err = copy.Copy(clonedRepoDir+"/"+repoPath, chartFolderDestName)

opts := copy.Options{
  Skip: func(src string) (bool, error) {
    return filepath.Base(src) == ".git", nil
  }
}

err = copy.Copy(clonedRepoDir+"/"+repoPath, chartFolderDestName, opts)

But I don't think we should do it by default, so we would need to add an option to skip copying this file:

repos:
  # ...
  - name: bootc-netbox-git
    type: git
    keep_git_directory: false
    url: https://github.com/bootc/netbox-chart.git

keepGitDirectory := true

for _, repo := range repos {
        if repo.kind == "git" && repo.name == chart["repo_name"] {
                keepGitDirectory = repo.keepGitDirectory
                chartUrl = repo.url
                break
        }
}

// ...

opts := copy.Options{
    Skip: func(src string) (bool, error) {
        return !keepGitDirectory && filepath.Base(src) == ".git", nil
    }
}

err = copy.Copy(clonedRepoDir+"/"+repoPath, chartFolderDestName, opts)

// ...
