The problem when i call kubectl get pod

Answer 1

May be thats because of 1. imagePullPolicy is set to "Never" and 2. image: mysql:5.6 does not seem to be present on the worker node where this pod got scheduled.
following are the two possible options:
Perform a manual pull of the image: mysql:5.6 on all worker nodes using
docker pull mysql:5.6
change imagePullPolicy to IfNotPresent.
