jerryxhx/ubuntu-systemd repository overview

⁠Systemd-enabled Ubuntu image for Docker

⁠About

This Docker image enhances the ubuntu image⁠ to be run like a VM or LXC container including systemd as init system and other utilities.

⁠Usage

For ubuntu LTS run:

docker run -d -it                       \
    -v /sys/fs/cgroup:/sys/fs/cgroup:ro \
    jerryxhx/ubuntu-systemd:latest

⁠Run at Docker for Mac

As the image mounts the systemd cgroup into the container, the host needs to have it mounted already. However, boot2docker doesn't have systemd installed and therefore this cgroup isn't available.

To get the cgroup mounted in the Docker VM, you can login into the VM by running docker-machine ssh and run the following code to apply the patch:

sudo -s
cat >> /var/lib/boot2docker/bootsync.sh <<EOF
mkdir /sys/fs/cgroup/systemd
mount -t cgroup -o none,name=systemd cgroup /sys/fs/cgroup/systemd
EOF
exit
