docker change cgroup driver to systemd

Question

I want to docker to start with systemd cgroup driver. for some reason it using only cgroupfs on my centos 7 server.

here is startup config file.

# system         


        

Answer 1

A solution that does not involve editing systemd units or drop-ins would be to create (or edit) the /etc/docker/daemon.json configuration file and to include the following:

{
  "exec-opts": ["native.cgroupdriver=systemd"]
}

After saving it, restart your docker service.

sudo systemctl restart docker

This solution obviously is only feasible if you would want to apply this system-wide.
