About this Hands-on Lab

Debugging is an essential skill for a Kubernetes application developer. This lab will present you with some debugging challenges. You will get a chance to practice your troubleshooting skills as you identify and solve problems with a Kubernetes app.

Learning Objectives

Successfully complete this lab by achieving the following learning objectives:

Fix a Broken Deployment

There is a Deployment in a cluster whose Pods are unable to enter the Running status. It is not simply the containers that are unready — the Pods themselves are not Running.

Identify this Deployment and correct the issue.

Fix an Application That Is Not Receiving User Traffic

The users-rest Deployment in the hive Namespace has Pods that are starting up (meaning that the Pods are in the Running status), but these Pods are not receiving user traffic.

Investigate to identify the problem and fix it.

Additional Resources

Welcome to HiveCorp, a software design company that is totally not run by bees!

We are working on building some applications in our Kubernetes cluster, but there are some issues. We need you identify what is wrong and fix these problems!

First, some Deployment's Pods are unable to start up (they won't even enter the Running status). Unfortunately, whoever reported this issue didn't provide much information, so you will need to locate this issue and fix it.

Second, a Deployment called users-rest has Pods that are running, but they are not receiving any user traffic. Investigate why this is happening and correct the issue.
