Pods 실습

Q1. How many pods exist on the system? In the current(default) namespace.

Q2. Create a new pod with the nginx image.

• Image name: nginx

Q3. How many pods are created now? Note: We have created a few more pods. So please check again.

Q4. What is the image used to create the new pods? You must look at one of the new pods in detail to figure this out.

Q5. Which nodes are these pods placed on? You must look at all the pods in detail to figure this out.

Q6. How many containers are part of the pod webapp? Note: We just created a new POD. Ignore the state of the POD for now.

Q7. What images are used in the new webapp pod? You must look at all the pods in detail to figure this out.

Q8. What is the state of the container agentx in the pod webapp? Wait for it to finish the ContainerCreating state

Q9. Why do you think the container agentx in pod webapp is in error? Try to figure it out from the events section of the pod.

Q10. What does the READY column in the output of the kubectl get pods command indicate?

Q11. Delete the webapp Pod. Once deleted, wait for the pod to fully terminate.

Q12. Create a new pod with the name redis and with the image redis123. Use a pod-definition YAML file. And yes the image name is wrong!

Q13. Now change the image on this pod to redis. Once done, the pod should be in a running state.
