docker snippet

Manage Docker as a non-root user

  1. Create the docker group.

    1
    $ sudo groupadd docker
  2. Add your user to the docker group.

    1
    $ sudo usermod -aG docker $USER
  3. Log out and log back in so that your group membership is re-evaluated.

    If testing on a virtual machine, it may be necessary to restart the virtual machine for changes to take effect.

    On a desktop Linux environment such as X Windows, log out of your session completely and then log back in.

    On Linux, you can also run the following command to activate the changes to groups:

    1
    $ newgrp docker
  4. Verify that you can run docker commands without sudo.

    1
    $ docker run hello-world
