About this Hands-on Lab

You are a container engineer at Cube4Lyf, an e-gaming platform geared towards puzzle and logic games. One of the pods running a newly launched game is failing. You need to identify the error causing the pod to fail and to extract the error for the logging agent to pick up so the developers, who don’t have access to this environment, can view the error and create a patch.

Learning Objectives

Investigate the failed pod

The pod puzzle-plaza is in a nonworking state. Using your Kubernetes troubleshooting tools, idenitify the error message.

hint: the go template for this is
kubectl get pod puzzle-plaza -o go-template="{{range .status.containerStatuses}}{{.lastState.terminated.message}}{{end}}"
