docker-cli package should include buildx/app plugins
The upstream docker-ce-cli 19.03 packages from the docker repositories have started including two cli plugins: docker app
and docker buildx
.
The alpine docker-cli package should also include these.
From the debian packages as a reference:
dpkg -L docker-ce-cli | grep cli-plug
/usr/libexec/docker/cli-plugins
/usr/libexec/docker/cli-plugins/docker-app
/usr/libexec/docker/cli-plugins/docker-buildx
The current workflow as documented https://docs.docker.com/buildx/working-with-buildx/ does not work with the alpine-provided package due to the buildx plugin being unavailable.
