Solutions: Before You Begin Exercises

This chapter provides complete, verified solutions for the three exercises at the end of Chapter 2. Each solution includes exact commands, expected output, and explanations of what to look for when verifying your work.

How to use these solutions:

1. Attempt the exercise first. Spend at least 15 minutes on each exercise before looking at the solution. Getting stuck and working through problems builds stronger recall than reading the answer.

2. Compare your approach. If your solution works but differs from what is shown here, that is fine — there are often multiple valid approaches. Focus on whether your result meets the stated requirements.

3. Check the verification steps. Every solution ends with concrete verification commands. Run these to confirm your setup matches the expected state.

4. Read the troubleshooting notes. Common mistakes are called out with their symptoms and fixes. If you hit an error during the exercise, check these before starting over.

The solutions are split into two sections: the first covers cluster creation and shell configuration (Exercises 1 and 2), and the second covers image loading and Pod creation (Exercise 3). This separation matches the natural breakpoint between infrastructure setup and workload deployment.
