This is a 'Practical Linux Troubleshooting Course' where you analyze and solve problems together with generative AI, based on a Docker practice environment that reproduces 5 representative failures that occur in actual Linux operating environments. Even those who were overwhelmed about where to start examining problems can learn the problem-solving approach and thought process of field engineers through AI guidance.

The Practical Guide covers overall infrastructure as well as shell scripting. We structured it focusing mainly on practical scenarios and troubleshooting (problem resolution) that is frequently handled in practice!
