In the days of immutable infrastructure, what's the point of troubleshooting anything?

In my experience, when there is a problem with the image/application/container, the immutable infrastructure will just keep recreating the problem. Knowing how to diagnose common problems is still an important skill. Moreover, the machines that control images and containers are longer running than the containers they run, problems on these machines still need to be found and fixed.

In this tutorial we will look at the problems seen with Linux systems. We'll start with how various subsystems work: networking; filesystems; users/groups; and permissions. We'll then move on to look at tools to inspect running systems and of course strace. The focus will be on "off the shelf" tools and how to use them.
