Make "docker login" in spec execution optional. Note that it has anyway limited (if any) effect as docker registry mirror cache is used and docker login does not really have expected affect. The registry mirror cache itself needs to be configured with respective credentials.

What about registry_spec.cr where docker login is mandatory? There is code like:

if ENV["DOCKERHUB_USERNAME"]? && ENV["DOCKERHUB_PASSWORD"]?
result = Dockerd.exec("docker login -u $DOCKERHUB_USERNAME -p $DOCKERHUB_PASSWORD", force_output: true)
Log.info { "Docker Login output: #{result[:output]}" }
else
puts "DOCKERHUB_USERNAME & DOCKERHUB_PASSWORD Must be set.".colorize(:red)
exit 1
end

Good point. Currently it passes because DOCKERHUB_USERNAME are set (but empty string) so the condition is true. Docker login fails but is ignored. At the end the test passes, despite not being logged in to dockerhub.
