Answer 1

This is known issue with systemd-based OSes inside Docker containers.

Short answer: as well as replacing fakesystemd with systemd you need to attach /sys/fs/cgroup as a read-only volume into the container, build the image and then run it in "privileged" mode.

This is the best guide I've found for this. It uses Centos as the example, but should work with any systemd-based OS.
