# This workflow builds the config server and creates a multi-arch image for it. # The image is then pushed to Docker Hub. # # The workflow consists of the following jobs: # 1. build-config-server-jar: Builds the config server and uploads the resulting JAR as an artifact. # 2. dependency-submission: Generate a dependency graph. # 2. build-docker-images: Builds a Docker image for multiple platforms with the matrix strategy. # 3. merge-images: Merges the images for the different platforms into a manifest list and pushes it to Docker Hub. # To make the build faster, we use a matrix strategy to build the image for multiple platforms in parallel. # The build of the first job is copied over to the image build jobs, so that the application build is only done once. # QUEMU is used to emulate the different platforms on the GitHub runner. # For more information about how to build multi-arch images and advanced settings with Docker Buildx in GitHub actions, see: # https://docs.docker.com/build/ci/github-actions/multi-platform/ name: Branch Continuous Integration on: push: env: REGISTRY_IMAGE: inspectit/inspectit-gepard-configserver GITHUB_TOKEN: ${{ secrets.GITHUB_TOKEN }} jobs: build-config-server-jar: runs-on: ubuntu-latest steps: - uses: actions/checkout@v4 - name: Set up JDK 21 uses: actions/setup-java@v4 with: java-version: '21' distribution: 'temurin' # Configure Gradle for optimal use in GiHub Actions, including caching of downloaded dependencies. # See: https://github.com/gradle/actions/blob/main/setup-gradle/README.md - name: Setup Gradle uses: gradle/actions/setup-gradle@417ae3ccd767c252f5661f1ace9f835f9654f2b5 # v3.1.0 with: build-scan-publish: true build-scan-terms-of-service-url: 'https://gradle.com/terms-of-service' build-scan-terms-of-service-agree: 'yes' - name: Build with Gradle run: ./gradlew build - name: Upload artifact uses: actions/upload-artifact@v3 with: name: config-server-artifact path: backend/build/libs/backend-0.0.1-SNAPSHOT.jar dependency-submission: runs-on: ubuntu-latest permissions: contents: write steps: - uses: actions/checkout@v4 - name: Set up JDK 21 uses: actions/setup-java@v4 with: java-version: '21' distribution: 'temurin' # Generates and submits a dependency graph, enabling Dependabot Alerts for all project dependencies. # See: https://github.com/gradle/actions/blob/main/dependency-submission/README.md - name: Generate and submit dependency graph uses: gradle/actions/dependency-submission@417ae3ccd767c252f5661f1ace9f835f9654f2b5 # v3.1.0 build-docker-images: runs-on: ubuntu-latest needs: build-config-server-jar strategy: fail-fast: false matrix: platform: - linux/amd64 - linux/arm64 steps: - name: Checkout uses: actions/checkout@v4 - name: Prepare run: | platform=${{ matrix.platform }} echo "PLATFORM_PAIR=${platform//\//-}" >> $GITHUB_ENV - name: Docker meta id: meta uses: docker/metadata-action@v5 with: images: ${{ env.REGISTRY_IMAGE }} - name: Download artifact uses: actions/download-artifact@v3 with: name: config-server-artifact path: ./ # Download artifact to the root of the Docker build context - name: Set up QEMU uses: docker/setup-qemu-action@v3 - name: Set up Docker Buildx uses: docker/setup-buildx-action@v3 - name: Login to Docker Hub uses: docker/login-action@v3 with: username: ${{ vars.DOCKERHUB_USERNAME }} password: ${{ secrets.DOCKERHUB_TOKEN }} - name: Build and push by digest id: build uses: docker/build-push-action@v6 with: context: . file: "./backend/Dockerfile-CR" platforms: ${{ matrix.platform }} labels: ${{ steps.meta.outputs.labels }} outputs: type=image,name=${{ env.REGISTRY_IMAGE }},push-by-digest=true,name-canonical=true,push=true - name: Export digest run: | mkdir -p /tmp/digests digest="${{ steps.build.outputs.digest }}" touch "/tmp/digests/${digest#sha256:}" - name: Upload digest uses: actions/upload-artifact@v4 with: name: digests-${{ env.PLATFORM_PAIR }} path: /tmp/digests/* if-no-files-found: error retention-days: 1 merge-images: runs-on: ubuntu-latest needs: build-docker-images steps: - name: Download digests uses: actions/download-artifact@v4 with: path: /tmp/digests pattern: digests-* merge-multiple: true - name: Set up Docker Buildx uses: docker/setup-buildx-action@v3 - name: Docker meta id: meta uses: docker/metadata-action@v5 with: images: ${{ env.REGISTRY_IMAGE }} - name: Login to Docker Hub uses: docker/login-action@v3 with: username: ${{ vars.DOCKERHUB_USERNAME }} password: ${{ secrets.DOCKERHUB_TOKEN }} - name: Create manifest list and push working-directory: /tmp/digests run: | docker buildx imagetools create $(jq -cr '.tags | map("-t " + .) | join(" ")' <<< "$DOCKER_METADATA_OUTPUT_JSON") \ $(printf '${{ env.REGISTRY_IMAGE }}@sha256:%s ' *) - name: Inspect image run: | docker buildx imagetools inspect ${{ env.REGISTRY_IMAGE }}:${{ steps.meta.outputs.version }}
