I create a Helm chart that depends on several sub charts. I add the sub charts in the file Chart.yaml, this works well for charts from the stable repository.

But I also want to add dependencies on other charts. Currently I use Helm install https://github.com/.../releases/my-chart.tgz to install charts, which does not work in the Chart.yaml file at the moment. Is there a way to use this in the dependency field in the Chart.yaml file?

Is there also a way to use a git repository https://github.com/my-chart/ as a reference to install a chart as a dependency?

Or is it really only possible to use chart repositories or locale chart directorys?

Thanks
