I have tried several times to apply Kubernetes pod with this Yaml file but don't understand the problem. It is always showing the error.

 ''' Failed to pull image "mongo": rpc error: code = Unknown desc = context deadline exceeded Warning Failed 13s kubelet Error: ErrImagePull Normal BackOff 13s kubelet Back-off pulling image "mongo" Warning Failed 13s kubelet Error: ImagePullBackOff '''

If anyone can help. I am stuck here for several days.

Answer 1

instead of "mongo" for the image use this: "registry.hub.docker.com/library/mongo"

Answer 2

You are missing the image tag. use mongo:latest
