# 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/
