1.准备k8s集群

1. 准备一台机器用来部署单节点kubernetes,机器地址192.168.1.10

2. 使用kubekey安装1.27.0版本的kubernetes：

apt install conntrack socat
export KKZONE=cn
kk create cluster --with-kubernetes=v1.27.0 --container-manager=containerd 

2. 安装cloudcore

使用keadm安装cloudcore：

keadm init --advertise-address="192.168.1.10"

获取云端token：

# keadm gettoken
27a37ef16159f7d3be8fae95d588b79b3adaaf92727b72659eb89758c66ffda2.eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJleHAiOjE1OTAyMTYwNzd9.JBj8LLYWXwbbvHKffJBpPd5CyxqapRQYDIXtFZErgYE

3. 加入边缘节点

1. 准备一台机器作为边缘节点192.168.1.11，在该节点安装containerd：

# 安装containerd runc cni
wget https://mirror.ghproxy.com/https://github.com/containerd/containerd/releases/download/v1.7.14/containerd-1.7.14-linux-amd64.tar.gz
tar Cxzvf /usr/local containerd-1.7.14-linux-amd64.tar.gz
systemctl daemon-reload
systemctl enable --now containerd
wget https://mirror.ghproxy.com/https://github.com/opencontainers/runc/releases/download/v1.1.12/runc.amd64
install -m 755 runc.amd64 /usr/local/sbin/runc
wget https://mirror.ghproxy.com/https://github.com/containernetworking/plugins/releases/download/v1.4.1/cni-plugins-linux-amd64-v1.4.1.tgz
mkdir -p /opt/cni/bin
tar Cxzvf /opt/cni/bin cni-plugins-linux-amd64-v1.4.1.tgz

 配置containerd:

containerd config default > /etc/containerd/config.toml
systemctl restart containerd

修改配置文件：

[plugins."io.containerd.grpc.v1.cri"]
  sandbox_image = "kubeedge/pause:3.6"

重启containerd:

systemctl restart containerd

2. 加入边缘节点

keadm join --cloudcore-ipport=192.168.1.10:10000 --token=27a37ef16159f7d3be8fae95d588b79b3adaaf92727b72659eb89758c66ffda2.eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJleHAiOjE1OTAyMTYwNzd9.JBj8LLYWXwbbvHKffJBpPd5CyxqapRQYDIXtFZErgYE

3. 边缘节点配置CNI

$ mkdir -p /etc/cni/net.d/

$ cat >/etc/cni/net.d/bridge.conf <<EOF
{
  "cniVersion": "0.3.1",
  "name": "containerd-net",
  "type": "bridge",
  "bridge": "cni0",
  "isGateway": true,
  "ipMasq": true,
  "ipam": {
    "type": "host-local",
    "subnet": "10.88.0.0/16",
    "routes": [
      { "dst": "0.0.0.0/0" }
    ]
  }
}
EOF

4. 查看节点：
