Discuss Docker DCA Exam Topic 2 Question 126

Does this command display all the pods in the cluster that are labeled as 'env: development'?

Solution: 'kubectl get pods -I env=development'

AYes

BNo

Suggested Answer: B

The command 'kubectl get pods -I env=development' willnotdisplay all the pods in the cluster that are labeled as 'env: development'.This is because the -I flag isnota valid option for kubectl get pods1.The correct flag to use is --selector or -l, which allows you to filter pods by labels2. Therefore, the correct command to display all the pods in the cluster that are labeled as 'env: development' is:

kubectl get pods --selector env=development

kubectl get pods -l env=development

kubectl Cheat Sheet | Kubernetes

Labels | Kube by Example

I hope this helps you understand the command and the label, and how they work with Kubernetes and pods. If you have any other questions related to Docker, please feel free to ask me.
