I am a beginner learning about Kubernetes. I tried pulling an unofficial image from a private registry for zookeeper in my yaml file for testing but the pod status was ImagePullBackOff. Somehow I got that error rectified and the image was pulled successfully but the new error being reflected for pod status is CrashLoopBackOff. Upon using the command "kubectl logs -f -p zookeeper-n1-pod-0 -c zookeeper-n1 -n test-1" or using "kubectl logs podname" command in any way or form in putty terminal, there isn't any output, the cursor just moves to the next line. I tried "exit $?" command to see the exit status of my previous command and got the output as 0 which means that the last command was executed successfully yet I see the pod status as CrashLoopBackOff. I am not able to solve this issue as no logs are present. What is the probable cause and solution for this?

Thanks in advance!!
