What you'll learn

Docker containers, images builds, networking, and volumes can fail in a variety of ways with a variety of noise. In this course, Tactics and Tools for Troubleshooting Docker, you’ll gain the ability to systematically diagnose and resolve the most common issues that arise across the container lifecycle. First, you’ll explore the core diagnostic toolkit — using docker logs, docker inspect, docker stats, docker exec, and docker debug to investigate running, stopped, and shell-less containers, and using prune commands to keep your environment clean. Next, you’ll discover how to resolve build and image failures, including misconfigured build contexts and tar/YAML errors, registry authentication issues, and problems with vulnerable base images. Finally, you’ll learn how to diagnose and resolve a variety of networking and storage problems, including port conflicts, DNS resolution failures, container-to-host connectivity, certificate errors, and volume mount and permission issues. When you’re finished with this course, you’ll have the skills and knowledge of troubleshooting Docker needed to confidently diagnose container, image, network, and storage issues.
