If you want to build multi-platform (OS/Arch) Docker images, then you must install buildx. On macOS, an easy way to install buildx is to install Docker Desktop Edge.
Images are based on the Docker official AdoptOpenJDK 11 JRE Hotspot image. If you want to build the Karaf image you have the following choices:
If you run build.sh without arguments then you could see how to usage this command.
Usage: build.sh --from-local-dist [--archive <archive>] [--image-name <image>] [--build-multi-platform <comma-separated platforms>] build.sh --from-release --karaf-version <x.x.x> [--image-name <image>] [--build-multi-platform <comma-separated platforms>] build.sh --help If the --image-name flag is not used the built image name will be 'karaf'. Check the supported build platforms; you can verify with this command: docker buildx ls The supported platforms (OS/Arch) depend on the build's base image, in this case [adoptopenjdk:11-jre-hotspot](https://hub.docker.com/_/adoptopenjdk?tab=tags&page=1&name=11-jre-hotspot).
To create the docker image from local distribution) you can execute the command below. Remember that before you can successfully run this command, you must build the project (for example with the command mvn clean install -DskipTests). For more info you can read: Building Apache Karaf
./build.sh --from-local-dist
For create the docker image from the local dist version but with the archive, you can execute the below command. Remember that before you can successfully run this command.
./build.sh --from-local-dist --archive ~/home/amusarra/apache-karaf-4.2.9.tar.gz
You can also specify the image name with the --image-name flag, for example (replacing the version, image name, and targets as appropriate):
./build.sh --from-local-dist --archive ~/Downloads/apache-karaf-4.2.9.tar.gz --image-name myrepo/mykaraf:x.x.x
If you want to build the docker image for a specific version of Karaf you can run build.sh command in this way (replacing the version, image name, and targets as appropriate):
./build.sh --from-release --karaf-version 4.2.9 --image-name myrepo/mykaraf:x.x.x
If you want to build the container for a specific version of Karaf and specific version of the platform, and push the image to the Docker Hub repository, you can use this command (replacing the version, image name, and targets as appropriate):
./build.sh --from-release --karaf-version 4.2.9 --image-name myrepo/mykaraf:x.x.x \ --build-multi-platform linux/arm64,linux/arm/v7,linux/amd64
Below is the output you should get from running the previous command.
