执行 kubeadm init 时出现卡在了 [apiclient] Created API client, waiting for the control plane to become ready
这里，查看日志
journalctl -xeu kubelet
发现是 gcr.io/google_containers/pause-amd64:3.0 没有pull下来，找到解决方法：
docker pull docker.io/kubernetes/pause docker tag docker.io/kubernetes/pause gcr.io/google_containers/pause-amd64:3.0
