Also adjusts the build image to use the opencloudeu/golang image. So
we're in sync with how the binaries are built in CI. It already contains
all the required dependencies.
Always including the parent directory into the build context was a bad
idea. This reverts the change and only add the opencloud tree to the
build context by default.
To build a docker image with workspaces enabled as new make target
"dev-docker-with-workspace" is introduced that adjust the docker build
call accordingly (by setting the right build context and the new SRCDIR
arg to point to the correct directory for the opencloud tree).
be careful, the env:OC_EDITION, env:FRONTEND_EDITION, and conf:edition got removed as part of this commit, no deprecation because the flag is build time only!
* Dockerfile.multiarch: use bind- and cache-mounts to speedup build
Use a cache mount for go build cache in the build container and mount
the sources as a bind mount as recommended in
https://docs.docker.com/build/cache/optimize/ this largely speeds up the
container build for subsequent builds.
* Use Dockerfile.multiarch for "dev-docker" target
Let's remove some redundancy. AFAICS the Docker.multiarch does
everything the Docker.linux.* files did. And with the build caches
enable it should be just as quick as building on the host.
* Dockerfile.multiarch: Align the alpine version of the base images
* Dockerfile: Reduce build context by adding more files to .dockerignore
