helm: helm chart pull --> Error: tag explicitly required

I’m getting an error while doing helm chart pull myregistry.azurecr.io/myapp:13546: Error: tag explicitly required.

I was able previously to successfully run helm chart push myregistry.azurecr.io/myapp:13546, so I’m confirming that my chart resides in my registry. Furthermore, if I’m trying with a Tag X.X.X or vX it’s working well.

Output of helm version: version.BuildInfo{Version:"v3.2.1", GitCommit:"fe51cd1e31e6a202cba7dead9552a6d418ded79a", GitTreeState:"clean", GoVersion:"go1.13.10"}

Output of kubectl version: N/A

This should be fixed in Helm 3.7+ with the recent changes to the OCI getter implementation. helm chart pull has been removed entirely in favour of Helm’s getter mechanism. Now you can pull charts from an OCI registry similar to a chart repository.

To fetch the latest release:

helm fetch oci://myregistry.com/myapp

To fetch v1.0.0:

helm fetch oci://myregistry.com/myapp --version v1.0.0

See https://helm.sh/docs/topics/registries/ for more information.

Hi, I think the bug still occures. i have image xxx.azurecr.io/helm/schema-service:0.1.0 and get the same error. .\environment-executables\helm.exe version version.BuildInfo{Version:"v3.5.4", GitCommit:"1b5edb69df3d3a08df77c9902dc17af864ff05d1", GitTreeState:"clean", GoVersion:"go1.15.11"}

@mathieu-benoit - thanks for verifying. We need to improve the code for parsing references.

Yep like mentioned on the description of the issue above, I could confirm that if the tag is in those formats: X.X.X or vX (prefixed with a v), it’s working fine.
