[docker] capture logs of running containers, add ubuntu support

Query `docker ps` and capture log output from current running containers.
Additionally, add support for Ubuntu systems and address a nuance where Ubuntu
systems use a different binary name for docker since a previous package already
owns the docker binary name.
