Analysis of permissions required to run docker

Running Docker requires root privileges.

To solve the problem that non-root users do not have permission to run docker commands, the method is as follows:

Method 1:

Use sudo to obtain administrator privileges and run docker commands. This method has many limitations when executing docker commands through scripts.

Method 2:

When the docker daemon is started, the user group named docker is given the permission to read and write the Unix socket by default. Therefore, as long as the docker user group is created and the current user is added to the docker user group, the current user will have the permission to access the Unix socket and can execute docker-related commands.

sudo groupadd docker #Add docker user group sudo gpasswd -a $USER docker #Add the logged in user to the docker user group newgrp docker #Update the user group
