URL: https://github.com/apache/gravitino/pull/10515
### What changes were proposed in this pull request?
This PR adds support for publishing Gravitino Helm charts to OCI registry
(Docker Hub) and updates documentation. The changes include:
1. **GitHub Actions Workflow**
- Created `.github/workflows/chart-release.yaml` for automated chart
publishing
- Supports publishing all 3 charts or selective publishing
- Includes token validation and configurable Docker repository
2. **Chart Name Updates**
- Updated `Chart.yaml` files to include `-helm` suffix for OCI registry
compatibility:
- `gravitino` → `gravitino-helm`
- `gravitino-iceberg-rest-server` → `gravitino-iceberg-rest-server-helm`
- `gravitino-lance-rest-server` → `gravitino-lance-rest-server-helm`
3. **Artifact Hub Integration**
- Added `artifacthub-repo.yml` metadata files to each chart directory
- Enables automatic discovery and indexing on Artifact Hub
4. **Documentation Updates**
- Updated `docs/chart.md`, `docs/iceberg-rest-catalog-chart.md`, and
`docs/lance-rest-server-chart.md`
- Added OCI registry installation instructions
- Removed local chart installation methods for simplicity
- Created README.md files in each chart directory linking to detailed
documentation
### Why are the changes needed?
Currently, Gravitino Helm charts are not published to any public registry,
making it difficult for users to discover and install Gravitino on Kubernetes.
This PR enables:
1. **Easy Distribution**: Users can install charts directly from OCI
registry without cloning the repository
2. **Version Management**: Automated publishing with version control
3. **Discoverability**: Charts will be indexed on Artifact Hub for easy
discovery
4. **Simplified Installation**: Standard Helm workflow using `helm install
oci://...`
### Does this PR introduce _any_ user-facing change?
Yes. Users can now install Gravitino Helm charts directly from OCI registry:
**Pull charts:**
```bash
helm pull oci://registry-1.docker.io/apache/gravitino-helm --version 1.3.0
helm pull
oci://registry-1.docker.io/apache/gravitino-iceberg-rest-server-helm --version
1.3.0
helm pull oci://registry-1.docker.io/apache/gravitino-lance-rest-server-helm
--version 1.3.0
