Strimzi GitHub Actions

Shared GitHub Actions and CI workflows used across Strimzi repositories.

Actions

Dependency Actions

Actions for installing tools and setting up Kubernetes clusters.

Action	Description	Key Inputs
dependencies/install-docker	Sets up Docker with QEMU and Buildx for multi-platform builds	—
dependencies/setup-java	Installs Java and Maven	javaVersion (21), mavenVersion (3.9.9), javaDistro (temurin)
dependencies/install-helm	Installs Helm and helm-unittest plugin	helmVersion (v3.20.0), helmUnitTestVersion (v1.0.3)
dependencies/install-yq	Installs yq YAML processor	version (v4.6.3), architecture (amd64)
dependencies/install-shellcheck	Installs ShellCheck linter	version (0.11.0), architecture (amd64)
dependencies/install-syft	Installs Syft SBOM generation tool	version (1.20.0), architecture (amd64)
dependencies/install-ascii-doctor	Installs Ascii Doctor tool	rubyVersion (3.2)
dependencies/setup-kind	Creates a Kind cluster with local registry and cloud-provider-kind	kindVersion (0.31.0), controlNodes (1), workerNodes (1), cloudProviderVersion (0.6.0)
dependencies/setup-minikube	Creates a Minikube cluster with local registry	minikubeVersion (v1.38.0), kubeVersion (v1.38.0)

Build Actions

Actions for building, testing, and releasing Strimzi components.

Action	Description	Key Inputs
build/build-binaries	Builds and tests Java binaries using Makefile targets	clusterOperatorBuild (false), mainBuild (true), artifactSuffix (binaries)
build/build-containers	Builds and archives container images	architecture (amd64), imagesDir (required), containerTag (latest)
build/push-containers	Pushes container images and creates multi-arch manifests	architectures (required), registryUser (required), registryPassword (required)
build/load-containers	Loads container images into Kind/Minikube registry	registry (required: minikube/kind/external)
build/deploy-java	Deploys Java artifacts to Maven Central	projects (required), settingsPath (required)
build/release-artifacts	Builds release artifacts using Makefile	releaseVersion (required), artifactSuffix (required)
build/publish-helm-chart	Publishes Helm Chart as OCI artifact	releaseVersion (required), helmChartName (required)

Important

Build actions do not install their own dependencies (Java, yq, Helm, Docker, Shellcheck, Syft, etc.). Callers must install the required dependencies using the appropriate dependency actions before invoking a build action.

Important

The build-binaries action supports an clusterOperatorBuild input (default false) that enables Strimzi Kafka Operator specific build steps — Helm chart generation, CRD distribution, dashboard setup, documentation checks, and uncommitted changes verification. Other repositories should leave this disabled.

Test Workflows

test-dependencies.yml

Tests all dependency actions with version matrix combinations:

• Docker — Buildx multi-platform support verification
• Helm — version matrix, unittest plugin verification
• ShellCheck — version matrix, functional test
• Syft — version matrix
• yq — version matrix, functional test
• Java/Maven — Java 17/21 + Maven 3.9.9/3.8.8 matrix
• Kind — single/multi-node clusters, K8s version verification, registry access from inside cluster, node labels, cloud-provider-kind
• Minikube — version matrix with latest, K8s version verification, registry access

test-integrations.yml / reusable-test-integrations.yml

End-to-end integration tests that run the full build pipeline (build binaries, deploy Java, build/push containers, release artifacts, publish Helm) against multiple Strimzi repositories:

• strimzi-kafka-operator (with clusterOperatorBuild: true)
• strimzi-kafka-bridge
• kafka-access-operator
• strimzi-mqtt-bridge
• drain-cleaner
• client-examples

Warning

The rest of Strimzi repositories are not compatible yet and will be added in the future.

Usage

Reference actions from another Strimzi repository:

- uses: strimzi/github-actions/.github/actions/dependencies/setup-kind@main
