Multi-container Pods (10%)

Create a Pod with two containers, both with image busybox and command “echo hello; sleep 3600”. Connect to the second container and run ‘ls’

show

Easiest way to do it is create a pod with a single container and save its definition in a YAML file:

kubectl run busybox --image=busybox --restart=Never -o yaml --dry-run -- /bin/sh -c 'echo hello;sleep 3600' > pod.yaml
vi pod.yaml

Copy/paste the container related values, so your final YAML should contain the following two containers (make sure those containers have a different name):

containers:
  - args:
    - /bin/sh
    - -c
    - echo hello;sleep 3600
    image: busybox
    imagePullPolicy: IfNotPresent
    name: busybox
    resources: {}
  - args:
    - /bin/sh
    - -c
    - echo hello;sleep 3600
    image: busybox
    name: busybox2
kubectl create -f pod.yaml
# Connect to the busybox2 container within the pod
kubectl exec -it busybox -c busybox2 -- /bin/sh
ls
exit
# you can do some cleanup
kubectl delete po busybox
