Official CentOS systemd docker container
The container was created as a base container for systemd based services. There is a sample containter that makes use of this image (https://github.com/xrowgmbh/docker-systemd-example-httpd).
Sample httpd container
Here we show you how we can create a sample httpd container.
First create a Dockerfile and setup the required service or services. Systemd can launch multiple services.
FROM centos/systemd MAINTAINER "Your Name" <email@example.com> RUN yum -y install httpd; yum clean all; systemctl enable httpd.service EXPOSE 80 CMD ["/usr/sbin/init"]
Then build it.
docker build --rm --no-cache -t httpd .
docker run --privileged --name httpd -v /sys/fs/cgroup:/sys/fs/cgroup:ro -p 80:80 -d httpd
Finally use it.
