# 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****
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
