slafs/centos7-systemd repository overview

⁠============================================ Centos 7 with systemd on unprivileged Docker

This is a base Docker image for CentOS 7 with installed systemd (instead of fakesystemd). It can be ran without -- privileged flag.

As of 2014-11-17 00:00 UTC this actually works ;)

For reference about creating/running this image see:

• http://developerblog.redhat.com/2014/05/05/running-systemd-within-docker-container/⁠
• https://bugzilla.redhat.com/show_bug.cgi?id=1033604⁠

This image is based on work in https://github.com/maci0/docker-systemd-unpriv⁠ (without sshd)

Build it like this::

docker build --rm=true -t slafs/centos7-systemd .

Then run it like this::

docker run -d -v /sys/fs/cgroup:/sys/fs/cgroup:ro slafs/centos7-systemd /usr/lib/systemd/systemd

⁠Systemd

Currently I've noticed some issues after installing various services.

For example:

• when installing postgres you should comment out OOMScoreAdjust option from .service file.
• When installing httpd (apache) comment out PrivateTmp option from /usr/lib/systemd/system/httpd.service.

Keep in mind that there might be other caveats.
