| # This workflow is triggered on pushes to the main branch. | |
| # It builds the agent and creates a multi-arch image for it. | |
| # The image is then pushed to Docker Hub. | |
| # | |
| # The workflow consists of three jobs: | |
| # 1. build-agent: Builds the agent and uploads the resulting JAR as an artifact. | |
| # 2. build-image: Builds a Docker image for multiple platforms with the matrix strategy. | |
| # 3. merge: 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/ | |
