This guide will show you how to fix the error Got permission denied while trying to connect to the Docker daemon socket at unix:///var/run/docker.sock when trying to run docker commands.

The Docker daemon binds to a Unix socket instead of a TCP port, but only root users can access this socket by default, hence, when you run docker commands without sudo, you will get the error below:

~ $ docker run hello-world

docker: Got permission denied while trying to connect to the Docker daemon socket at unix:///var/run/docker.sock: Post "http://%2Fvar%2Frun%2Fdocker.sock/v1.24/containers/create": dial unix /var/run/docker.sock: connect: permission denied.
See 'docker run --help'.
