describe pod顯示報錯：
Readiness probe failed: 2021-10-02 08:02:33.072 [INFO][205] confd/health.go 180: Number of node(s) with BGP peering established = 0
calico/node is not ready: BIRD is not ready: BGP not established with 192.168.232.133,192.168.232.134
原因是master節點網卡比較多，calico選擇了錯誤的網卡，
修改calico.yaml，指定正確的網卡名稱即可。
增加在env中增加：
– name: IP_AUTODETECTION_METHOD
value: “interface=ens*”
