This article is about how to use the sudo command in a docker container. The editor thinks it is very practical, so share it with you as a reference and follow the editor to have a look.

Sudo is used to run the docker command because the daemon thread of Docker is bound to unix socket, not the TCP port. This socket belongs to root by default, and other users can access the socket file through sudo, so the docker service process runs under the root account.

Please execute the sudo command under the root user, or add sudo before the execution command line.

First check whether there are any user groups through instructions.

Cat / etc/group | grep docker

Create a docker user group without it

Sudo groupadd docker

Users join user groups

Sudo usermod-aG docker user name

Check whether it is valid

Cat / etc/group

Restart docker-daemon

Sudo systemctl restart docker

Add permissions to docker.sock

Sudo chmod a+rw / var/run/docker.sock
