Downloads¶

Note

The signed source archive is the official Apache release. The operator image and Helm chart are convenience binaries published to the GitHub Container Registry: dev / sha-<commit> tags and the 0.0.0-dev chart on every merge to main, <version>-rc<N> tags for release candidates, and <version> + latest for final releases.

Source Release¶

Per the ASF Release Policy, the signed source archive is the official Apache release; the operator image and Helm chart below are convenience binaries built from it.

Signed source archives, detached PGP signatures, and SHA-512 checksums are published to the ASF distribution site under https://downloads.apache.org/superset/kubernetes-operator-<version>/, for example kubernetes-operator-0.1.0/:

File	Description
`apache-superset-kubernetes-operator-<version>.tar.gz`	Source archive (a `git archive` of the release tag).
`apache-superset-kubernetes-operator-<version>.tar.gz.asc`	Detached PGP signature.
`apache-superset-kubernetes-operator-<version>.tar.gz.sha512`	SHA-512 checksum.

Verifying the Source Release¶

VERSION=0.1.0
BASE=https://downloads.apache.org/superset/kubernetes-operator-${VERSION}
curl -O ${BASE}/apache-superset-kubernetes-operator-${VERSION}.tar.gz{,.asc,.sha512}
curl -O https://downloads.apache.org/superset/KEYS
gpg --import KEYS
gpg --verify apache-superset-kubernetes-operator-${VERSION}.tar.gz{.asc,}
shasum -a 512 -c apache-superset-kubernetes-operator-${VERSION}.tar.gz.sha512

Operator Image¶

Multi-architecture operator images (linux/amd64, linux/arm64) are published to the GitHub Container Registry on every merge to main and on version tags:

ghcr.io/apache/superset-kubernetes-operator

Pull¶

docker pull ghcr.io/apache/superset-kubernetes-operator:dev

Image Tags¶

Tag	Example	Description
`dev`	`dev`	Floating tag tracking the latest commit on `main`. Rebuilt on every merge.
`sha-<commit>`	`sha-1a2b3c4d5e6f7a8b9c0d1e2f3a4b5c6d7e8f9a0b`	Immutable tag for a specific commit (full Git SHA).
`<version>`	`0.1.0`	Semver release. Published when a version tag is pushed.
`<version>-rc<N>`	`0.1.0-rc1`	Release candidate.
`latest`	`latest`	Points to the highest stable (non-prerelease) release.

Choosing a Tag¶

Production: Pin to a semver tag (e.g., 0.1.0) or a sha- tag for full reproducibility.
Testing pre-release features: Use an RC tag (e.g., 0.1.0-rc1) or dev.
Avoid using latest or dev in production — these are mutable and will change without notice.

Image Signing¶

All images are signed with cosign using keyless OIDC signing via GitHub Actions. To verify:

cosign verify \
  --certificate-oidc-issuer https://token.actions.githubusercontent.com \
  --certificate-identity-regexp 'github\.com/apache/superset-kubernetes-operator' \
  ghcr.io/apache/superset-kubernetes-operator:<tag>

Helm Chart¶

The Helm chart is published as an OCI artifact to the GitHub Container Registry on every merge to main and on version tags.

Install from OCI¶

helm install superset-operator \
  oci://ghcr.io/apache/superset-kubernetes-operator/charts/superset-operator \
  --version <version> \
  --namespace superset-operator-system \
  --create-namespace

Replace <version> with a chart version from the table below. For the latest development build, use 0.0.0-dev.

Chart Versions¶

Tag	Description
`0.0.0-dev`	Floating tag tracking the latest commit on `main`.
`<version>` (e.g., `0.1.0`)	Semver release.
`<version>-rc<N>` (e.g., `0.1.0-rc1`)	Release candidate.

Install from Source¶

For development or to test unreleased changes, install directly from a source checkout:

helm install superset-operator charts/superset-operator \
  --namespace superset-operator-system \
  --create-namespace
