Every Kubernetes administrator will likely need to deal with a broken cluster at some point, whether a single node or the entire cluster is down. In this lab, you will be able to practice your troubleshooting skills. You will be presented with a broken Kubernetes cluster and asked to use your investigative skills to identify the problem and fix it.
Successfully complete this lab by achieving the following learning objectives:
- Determine What is Wrong with the Cluster
Explore the cluster and determine which node is having issues. Then see if you can determine what is causing the node to fail.
- Fix the Problem
Fix the issue with the broken node. Make sure your fix will keep the node working, even if the node is restarted again.
