Pushing a Helm chart to a registry

You can push Helm Charts to a Container Registry repository. Container Registry stores Helm charts the same way as conventional Docker Images.

Note

If you are using a Helm version lower than 3.7.1, re-upload the charts to the Container Registry repository when upgrading to a newer version.

To push a Helm chart:

CLI

Install Helm 3.7.1 or higher.
Enable Open Container Initiative support in the Helm client:
```
export HELM_EXPERIMENTAL_OCI=1
```
Authenticate your Helm client in the Container Registry registry using an Identity and Access Management token:
1. Get an Identity and Access Management token.
2. Run the command:
```
helm registry login cr.il.nebius.cloud -u iam
Password: <Identity and Access Management token>
```
  Result:
```
Login succeeded
```

Save the Helm chart locally:

helm package . --version <Helm chart version>

Result:

Successfully packaged chart and saved it to: /<path>/<Helm chart name>-<version>.tgz

Push the Helm chart to Container Registry:

helm push <Helm chart name>-<version>.tgz oci://cr.il.nebius.cloud/<registry ID>

Result:

Pushed: cr.il.nebius.cloud/<registry ID>/<Helm chart name>:<version>
Digest: <SHA256...>
