2. 安装边缘 Kubernetes master 节点
将下载的压缩包解压后，进入目录，执行下面的命令：
#成功执行后的结果需要记住，一会把节点加入到集群中是需要的 ./edgeadm init --kubernetes-version=1.22.6 --image-repository superedge.tencentcloudcr.com/superedge --service-cidr=10.244.0.0/16 --pod-network-cidr=10.233.0.0/16 --install-pkg-path ./kube-linux-*.tar.gz --apiserver-cert-extra-sans=114.116.101.254 --apiserver-advertise-address=192.168.0.245 --enable-edge=true --edge-version=0.9.0- 1
- 2
–enable-edge=true: 是否部署边缘能力组件，默认 true --enable-edge=false 表示安装原生 Kubernetes 集群，和 kubeadm 搭建的集群完全一样；
–install-pkg-path的值可以为机器上的路径，也可以为网络地址（比如：http://xxx/xxx/kube-linux-arm64/amd64-*.tar.gz, 能免密wget到就可以），注意用和机器体系匹配的Kubernetes静态安装包；
–image-repository：镜像仓库地址
–apiserver-cert-extra-sans=
IP/域名等>：这里的外网 IP 指的是边缘节点需要接入的云端控制面的公网 IP以及外网域名，apiserver 会签发相应的证书供边缘节点访问 –apiserver-advertise-address=
：这里的内网 IP 指的是 edgeadm 用于初始化 etcd 和 apiserver 需要绑定的节点内部 IP –edge-version=0.9.0：如果需要使用最新的 Kins 能力, 这里需要指定最新v0.9.0的版本（仅支持 Kubernetes 1.22.6）；如果不需要 Kins 能力，同时又希望能够使用类似 1.20 的低 K8s 版本，可以使用 v0.8.2版本，支持最新的云边隧道能力，支持云端 master、worker 和边缘节点三种类型节点的 7 层协议互通，适配更加完善
