DevOps: Puppet, Docker, and Kubernetes

Adding a nonroot user to administer Docker

For ease of use, we can allow a nonroot user to administer Docker by adding them to a Docker group.

Getting ready

1. Create the Docker group if it is not there already:

   $ sudo group add docker
   

2. Create the user to whom you want to give permission to administer Docker:

   $ useradd dockertest
   

How to do it…

Run the following command to allow the newly created user to administer Docker:

$ sudo  gpasswd -a dockertest docker

How it works…

The preceding command will add a user to the Docker group. The added user will thus be able to perform all Docker operations. This can be the security risk. Visit Chapter 9, Docker Security for more details.
