Manage GitHub and Gitlab accounts on a single machine with SSH keys on Linux For this example, We will use the same email address to produce two different SSH keys:
Automation with Docker It was far easier to learn how to use Docker than to dive into all the details of an application. Using Docker allows you to leverage pre-built, ready-to-use container images.

Docker networking overview lab In Docker networking, we will learn some basic concepts and prepares you to design and deploy your applications to take full advantage of these capabilities.
