"Containers are becoming the de facto standard for running applications in a cloud, which creates a growing need for a container orchestrator. This paradigm shift enables to run large and often distributed clusters efficiently. However, operators are still exposed to operating-system-level settings. Understanding how the container orchestrator works with the operating system is critical for the operation of a cluster, especially when talking about security.

In this workshop, we will briefly introduce OpenShift, persistent volumes, security context constraints, file permissions, SELinux, and how they all work together. Attendees will gain hands-on experience with genuine issues, and learn how to debug and find solutions to those issues. A laptop capable of running a VM is recommended."
