Docker: Container: CentOS7: Failed to get D-Bus connection: Operation not permitted

At the beginning, going to prepare a CentOS7 container for testing a website.

When to start the httpd service, got this error, however.

$ sudo systemctl start httpd
Failed to get D-Bus connection: Operation not permitted

In fact, run any systemctl. Got the same failed.


Finally, found the answer:

docker run --privileged --name {container} -d {image} /sbin/init

docker run --privileged --name centos7 -d centos:7 /sbin/init
docker exec -ti centos7 bash
