Docker using non-root users

Docker using non-root users

Usually we use root when using Docker, the official statement is as follows:

The Docker daemon binds to a Unix socket instead of a TCP port. By default, Unix socket is owned by the user root and other users can access it with sudo. For this reason, Docker Daemon always runs as the root user.
To avoid the Docker command, create a Unix group called Docker and add users to it. When the Docker daemon starts, it makes the ownership to the Unix socket read/writable by the Docker group.

The following is a procedure to create a docker group using a non-root user action

sudo groupadd Docker

Add the current user to the Docker group

sudo gpasswd-a ${user} docker

Restart the Docker service (below is the CentOS7 command)

sudo systemctl restart Docker

The current user exits the system and logs back in Run Docker command
