This is useful for a CI server that is itself a docker container and which mounts the docker unix socket
from the host machine. In that case, the server cannot spawn child containers but will instead spawn sibling
containers which cannot be addressed at "localhost". In order to address the sibling containers you need to resolve
the hostname of the host machine, which this method will accomplish.
