[shizgchina]

4.22、ubuntu系统，非root用户安装时，在kubernetes-apps/network_plugin/calico: start calico resources get http://localhost:8080/api?timeout=32s: dial tcp 127.0.0.1: 8080: connect: connection refused

答：采用root用户安装脚本。 4.23、FAILED - RETRYING: container_download | Download containers if pull is required or told to always pull (all nodes) (4 retries left)

可见，4.23 需要换行。
