    The cause: I think the cause of this error is that on Centos7, the systemd daemon is used to launch and stop all services. The systemctl command will simply try to communicate with the daemon through a d-bus channel, which is where the message originates.

    The solution: To avoid this situation, you need to use this command:

    docker run -d -it --privileged {Image ID} /usr/sbin/init

    And gain access to the container’s root.

    systemctl start httpd.service

  2. For more information on @Guido’s answer: I copied systemctl.py from hier and placed it in the same directory with my Dockerfile and then added the following to my Dockerfile: 

    COPY systemctl.py /usr/bin/systemctl
RUN chmod a+x /usr/bin/systemctl

    This allowed me to create a sshd service similar to this: 

    service sshd start
