Practice Test - Init-Containers

• Take me to Practice Test

Solutions to practice test - init-containers

• Identify the pod that has an initContainer configured.

  ``` $ kubectl get pods $ kubectl describe pods ```

• What is the image used by the initContainer on the blue pod?

  ``` $ kubectl describe pods blue ```

• Run the command kubectl describe pod blue and check the state field of the initContainer.

  ``` $ kubectl describe pod blue ```

• Check the reason field of the initContainer

  ``` $ kubectl describe pod blue ```

• Run the command kubectl describe pod purple

  ``` $ kubectl describe pod purple ```

• Run the kubectl describe pod purple command and look at the container state

  ``` $ kubectl describe pod purple ```

• Check the commands used in the initContainers. The first one sleeps for 600 seconds (10 minutes) and the second one sleeps for 1200 seconds (20 minutes)

  ``` $ kubectl describe pod purple ```

• Update the pod red to use an initContainer that uses the busybox image and sleeps for 20 seconds

  ``` $ kubectl get pod red -o yaml > red.yaml $ kubectl delete pod red ```

  Update the red.yaml with sleep 20 seconds

  ``` $ kubectl create -f red.yaml ```

• Check the command used by the initContainer. Looks like there is a type in sleep command. Fix it, it should be sleep 2 not sleeeep 2

  ``` $ kubectl describe pod orange $ kubectl get pod orange -o yaml > orange.yaml $ kubectl delete pod orange Update the orange.yaml with correct sleep command and recreate the pod $ kubectl create -f orange.yaml ```
