Overview of this book

Docker is an open source tool used for creating, deploying, and running applications using containers. With more than 100 self-contained tutorials, this book examines common pain points and best practices for developers building distributed applications with Docker. Each recipe in this book addresses a specific problem and offers a proven, best practice solution with insights into how it works, so that you can modify the code and configuration files to suit your needs. The Docker Cookbook begins by guiding you in setting up Docker in different environments and explains how to work with its containers and images. You’ll understand Docker orchestration, networking, security, and hosting platforms for effective collaboration and efficient deployment. The book also covers tips and tricks and new Docker features that support a range of other cloud offerings. By the end of this book, you’ll be able to package and deploy end-to-end distributed applications with Docker and be well-versed with best practice solutions for common development problems.

Adding a nonroot user to administer Docker

For ease of use, we can allow a nonroot user to administer Docker by adding it to a Docker group. This is not required when using Docker on Mac or Windows.

Getting ready

To prepare to add a nonroot user to administer Docker, go through the following steps:

  1. Create the Docker group, if it is not there already:
    $ sudo groupadd docker
  1. Create the user to whom you want to give permissions to administer Docker:
    $ sudo useradd dockertest

How to do it...

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

    $ sudo usermod -aG docker dockertest

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.
