In this lesson
Prepare for the Linux+ XK0-006 exam (CompTIA Linux+ V8). In this lesson: container runtimes, images and Dockerfiles (pull, build, tag, prune), running and managing containers (run, logs, exec, inspect, rm), volumes and SELinux labels, container networks and port mapping, and privileged, unprivileged, and rootless containers, with Pinecrest Media, a fictional video streaming company, as the running example. Includes three original practice questions.
Preview the topics
- An encoding image must always run ffmpeg, and users should be able to change only its arguments when they start a container. How should the Dockerfile set that up?
- On a Rocky Linux server in enforcing mode, a container gets permission denied on a host directory that is mapped into it. Only this container should use that directory. What should the admin add?
- A legacy media server in a container must appear on the office network as its own device, with its own MAC address. Which network type fits?
