华为云搭建Kubeedge

创建一个CCE集群，并创建一个节点，云端节点cloud–>4V8G
创建一个ECS主机，边缘节点edge–>4V8G

部署云端

云端cloud节点已安装kubernetes，边缘节点不需要

[root@cloud ~]# kubectl get pod -A

安装cloudcore

# --adverties-address-->填写公网
# --profile-->对应刚刚安装的版本号
[[root@cloud ~]# keadm init --advertise-address=124.70.211.167 --profile version=v1.11.1

# 设置edge mesh
[root@edge ~]# vim /etc/nsswitch.conf
修改为 hosts:   dns files mdns4_minimal [NOTFOUND=return]

# 设置ip forward
