If you would like to use Docker as a non-root user, you should now consider
adding your user to the "docker" group with something like:

  sudo usermod -aG docker your-user

Remember that you will have to log out and back in for this to take effect!

WARNING: Adding a user to the "docker" group will grant the ability to run
         containers which can be used to obtain root privileges on the
         docker host.
         Refer to https://docs.docker.com/engine/security/security/#docker-daemon-attack-surface
         for more information.

添加用户到 docker 组

[email protected]:~ $ sudo usermod -aG docker pi

卸载 Docker CE

$ sudo apt-get purge docker-ce

容器、卷、镜像等不会自动删除，执行命令手动清理：

$ sudo rm -rf /var/lib/docker
