JupyterHub Spawner using systemd for resource isolation
If you want to use Linux Containers (Docker, rkt, etc) for isolation and security benefits, but don't want the headache and complexity of container image management, then you should use the SystemdSpawner.
With the systemdspawner, you get to use the familiar, traditional system administration tools, whether you love or meh them, without having to learn an extra layer of container related tooling.
