Error I met

I met error message like Init:ImagePullBackOff when I tried to create calico pod.

kubectl get pods --all-namespaces
NAMESPACE     NAME                                                     READY   STATUS                  RESTARTS   AGE   
kube-system   calico-kube-controllers-xxxxxxxxxx-yyyyy                 1/1     Running                 1          13h   
kube-system   calico-node-xxxxx                                        0/1     Init:ImagePullBackOff   0          13h

Why it happened

Yes, it’s because of changed docker hub policy. Recently, I’m in an environment that about 20~30 people use 4 public IP addresses. So, it’s easy to reach docker hub pull rate limit.
