Is my guess correct? You guessed quite right. One advantage of docker is that once you pulled my container image, large layers installing various packages are used unmodified in a new build. Building a image with an alternative <uid:gid> pair will take just a few seconds. Initial pull of the image can take several minutes or longer depending on the network bandwidth. For instructions to install Docker Engine on Ubuntu, see: https://docs.docker.com/engine/install/ubuntu/. The command in the FAQ assumes your user id belong to the "docker" group. Otherwise, every docker command needs "sudo". One thing you need to care is the disk capacity under /var/lib/docker. If you are behind a corporate proxy, you need to setup proxy for docker service.
