Hi everybody,

I’m experiencing problem described here Use Helm to publish chart packages to Docker Hub · Issue #135 · docker/roadmap · GitHub

Is there any workaround to be able to push Helm chart to DockerHub

$ export HELM_EXPERIMENTAL_OCI=1

$ helm create blueberry

I have not heard any announcement from Docker that they would support storing helm charts. The Docker Registry v2 (Docker distribution) supports helm charts but that doens’t mean Docker Hub will. It doesn’t have the interface for searching helm charts, at least I have never seen any sign of that.

Let’s say Docker Hub supports it without encourageing us to push helm charts into our repositories. The documentation of helm uses a different reference format for helm charts:

https://helm.sh/docs/topics/registries/

helm push mychart-0.1.0.tgz oci://localhost:5000/helm-charts

Notice that oci:// at the beginning of the URI.

Is there any reason you don’t want to use https://artifacthub.io/ ?

Hi Ákos,

thanks for your reply.
My reason was to have a private but still hosted repo for charts.

as far as i understood, artifacthub is only supporting public accessible chart uploads.

Thank you for the answer. Could this help you to use GitHub as a private helm repository? Tutorial: Turning a GitHub Repo Into a Helm Chart Repo | Harness

I have never tried it so I am not sure it works in a private GitHub repository but if it does, it could be an alternative to Artifacthub

Hi,

i have also seen this as an alternative to use GitHub-pages on a private repo as a helmRepo.

thanks
