--set cloudcore.image.repository=registry.cn-hangzhou.aliyuncs.com/kubeedge/cloudcore \

--set cloudcore.image.tag=v1.19.2

sudo keadm init --advertise-address=<MASTER_IP> --kube-config=$HOME/.kube/config --set iptablesManager.mode="external" --kubeedge-version=1.19.2

# 打标签防止云端的一些 damonset pod 调度到边缘端****

kubectl get daemonset -n kube-system |grep -v NAME |awk '{print $1}' | xargs -n 1 kubectl patch daemonset -n kube-system --type='json' -p='[{"op": "replace","path": "/spec/template/spec/affinity","value":{"nodeAffinity":{"requiredDuringSchedulingIgnoredDuringExecution":{"nodeSelectorTerms":[{"matchExpressions":[{"key":"node-role.kubernetes.io/edge","operator":"DoesNotExist"}]}]}}}}]'

docker tag registry.aliyuncs.com/google_containers/metrics-server:v0.7.2 registry.k8s.io/metrics-server/metrics-server:v0.7.2

# 忽略 metrics -server的tls证书校验

kubectl patch deploy metrics-server -n kube-system --type='json' -p='[{"op": "add", "path": "/spec/template/spec/containers/0/args/-", "value":"--kubelet-insecure-tls"}]'

二、边缘点安装****

1、环境准备****

重复主节点上的步骤1-3，即环境准备、安装docker、 安装 cri-dockerd****

2 、安装cni****

sudo mkdir -p /opt/cni/bin

sudo tar -C /opt/cni/bin -xzvf cni-plugins-linux-arm64-v1.1.1.tgz

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

sudo vim /etc/cni/net.d/10-containerd-net.conflist

{

"cniVersion": "1.0.0",

"name": "containerd-net",

"plugins": [

{

"type": "bridge",

"bridge": "cni0",

"isGateway": true,

"ipMasq": true,

"promiscMode": true,

"ipam": {

"type": "host-local",

"ranges": [

[{

"subnet": "10.88.0.0/16"

}],

[{

"subnet": "2001:db8:4860::/64"

}]

"routes": [

{ "dst": "0.0.0.0/0" },

{ "dst": "::/0" }

]

}

{

"type": "portmap",

"capabilities": {"portMappings": true}

}

]

}

3、安装keadm****

重复主节点步骤5 安装keadm****

4、执行join命令****

sudo rm -rf /etc/kubeedge/

# CLOUD_CORE_IPPORT ，主节点+默认端口号10000，如10.32.6.65:10000****

# EDGE_NODE_NAME 自定义边缘节点名称，不可重复****

sudo ./keadm join \

--cloudcore-ipport= ${CLOUD_CORE_IPPORT} \

--token=${TOKEN} \

--kubeedge-version=1.19.2 \

--edgenode-name= ${EDGE_NODE_NAME} \

--remote-runtime-endpoint=unix:///var/run/cri-dockerd.sock \

--cgroupdriver=systemd
