Pod stays in waiting in kubernetes cluster

Question

I've created a cluster and deployed a simple web page. But when I check my pods status, it says waiting. I have been sitting patiently thinking it'll get created but its been an hour now and its still in the waiting stage. Why is that so?

Answer 1

If a Pod is stuck in the Waiting state, then it has been scheduled to a worker node, but it can’t run on that machine. The information from kubectl describe ... should be informative. The most common cause of Waiting pods is a failure to pull the image. There are three things to check:

• Make sure that you have the name of the image correct.
• Have you pushed the image to the repository?
• Run a manual docker pull <image> on your machine to see if the image can be pulled.

Hope it helps..
