Description

As seen in the example [dockerfile-base-as-arg|https://github.com/fabric8io/docker-maven-plugin/blob/master/it/dockerfile-base-as-arg/src/main/docker/Dockerfile] we tried to parametrize our docker-builds, the docker:build works fine, but the following docker:push crashes with:

[ERROR] Failed to execute goal io.fabric8:docker-maven-plugin:0.44.0:push (default-cli) on project xxx: Execution default-cli of goal io.fabric8:docker-maven-plugin:0.44.0:push failed: Given Docker name '${baseImage}' is invalid:
[ERROR] * image part '${baseImage}' doesn't match allowed pattern '[a-z0-9]+(?:(?:(?:[.]|__|[-]*)[a-z0-9]+)+)?(?:(?:/[a-z0-9]+(?:(?:(?:[.]|__|[-]*)[a-z0-9]+)+)?)+)?'
