How to fix docker: Got permission denied issue

If you want to run docker as non-root user then you need to add it to the docker group.

  1. Create the docker group if it does not exist
$ sudo groupadd docker
  1. Add your user to the docker group.
$ sudo usermod -aG docker $USER
  1. Run the following command or Logout and login again and run (that doesn’t work you may need to reboot your machine first)
$ newgrp docker
  1. Check if docker can be run without root
$ docker run hello-world

Reboot if still got error

$ reboot

Warning

The docker group grants privileges equivalent to the root user. For details on how this impacts security in your system, see Docker Daemon Attack Surface..
