What is the ImagePullBackoff error in Kubernetes and how to fix it?
Like CrashLoopBackoff, the ImagePullBackoff is not an error but a waiting status you might see in your kubernetes pods, with the backoff time increasing after every retry.
The error itself is "ErrImagePull", and it happens when there are issues when pulling the container image to the kubernetes node.
