Challenge: Troubleshooting Kubernetes

Challenge yourself by troubleshooting some issues in Kubernetes.

We'll cover the following...

Problem 1: Resolving resource error issues

We deployed the application below and it’s not running yet. When we check its status, it shows that the pod is in a pending state. Troubleshoot the issue and figure out a way to resolve it.

apiVersion: v1
kind: Pod
metadata:
  name: app
spec:
  containers:
  - name: container
    image: busybox
    command: ["/bin/sh", "-c", "while true; do echo 'Running...'; sleep 10; done"]
    resources:
      requests:
        cpu: "6"      
        memory: "10Gi"

Use the following run commands while you practice:
