1. create a namespace distro.Run a busybox pod name bbox with command i=0; while true; do echo "$i: $(date)"; i=$((i+1)); sleep 1; done in distro namespace. Tails logs of the pod.

   Solution

   # create the namespace
   k create ns distro
   
   # create pod with the specified command
   apiVersion: v1
   kind: Pod
   metadata:
     creationTimestamp: null
     labels:
       run: bbox
     name: bbox
     namespace: distro
   spec:
     containers:
     - image: busybox
       name: bbox
       command: ["sh","-c","i=0; while true; do echo '$i: $(date)'; i=$((i+1)); sleep 1; done"]
     dnsPolicy: ClusterFirst
     restartPolicy: Always
   status: {}
   
   # tail the logs
   k logs bbox -n distro -t

2. Create a bitto pod with busybox image. It runs a command ls \here. Check if the pod is running successfully, if not check why it's not running & then delete it.

   Solution

   # create the namespace
   k create ns nano
   
   # create pod with the specified command
   apiVersion: v1
   kind: Pod
   metadata:
     creationTimestamp: null
     labels:
       run: bitto
     name: bitto
   spec:
     containers:
     - image: busybox
       name: bitto
       command: ["sh","-c","ls /here"]
     dnsPolicy: ClusterFirst
     restartPolicy: Always
   status: {}
   
   # check details of the pod
   k describe po bitto
