Extending the dev container

The dev container is relatively large so we have split a base container which is available from ghcr.io/eclipse-ankaios/devcontainer.

If there is a need to include additional items in the dev container, please note that it is split into two parts due to its size:

• a base container which, in case of a change, needs to be build manually from .devcontainer/Dockerfile.base by running the following outside of the dev container:

  # Prepare the build with buildx. Depending on you environment
  # the following steps might be necessary:
  docker run --rm --privileged multiarch/qemu-user-static --reset -p yes
  # Create and use a new builder. This needs top be called only once:
  docker buildx create --name mybuilder --driver docker-container --bootstrap
  docker buildx use mybuilder
  
  # Now build new base image for the dev container
  cd .devcontainer
  docker buildx build -t ghcr.io/eclipse-ankaios/devcontainer-base:<version> --platform linux/amd64,linux/arm64 -f Dockerfile.base .
  

  In order to push the base image append --push to the previous command.

  Note: If you wish to locally test the base image in VSCode before proceeding, utilize the default builder and exclusively build for the default platform like

  docker buildx use default
  docker buildx build -t ghcr.io/eclipse-ankaios/devcontainer-base:<version> -f Dockerfile.base --load .
  

• a docker container which derives from the base image mentioned above is specified in .devcontainer/Dockerfile (so don't forget to reference your new version there once you build one).

If you want to add some additional tools, you can initially do it in .devcontainer/Dockerfile, but later on they need to be pulled in the the base image at some point in order to speed up the initial dev container build.
