下载metrics-server
准备证书
cat << EOF | tee /opt/kubernetes/ca_json/metrics-server.json
{
"CN": "metrics-server",
"key": {
"algo": "rsa",
"size": 2048
},
"names": [
{
"C": "CN",
"ST": "Shanghai",
"L": "Shanghai",
"O": "k8s",
"OU": "System"
}
]
}
EOF生成证书
cfssl gencert -ca=ca.pem -ca-key=ca-key.pem -config=ca-config.json -profile=kubernetes metrics-server.json | cfssljson -bare ./metrics-server
kube-apiserver需添加的参数
--proxy-client-cert-file=/opt/kubernetes/ssl/metrics-server.pem --proxy-client-key-file=/opt/kubernetes/ssl/metrics-server-key.pem --requestheader-allowed-names=aggregator --requestheader-client-ca-file=/opt/kubernetes/ssl/ca.pem --requestheader-extra-headers-prefix=X-Remote-Extra- --requestheader-group-headers=X-Remote-Group --requestheader-username-headers=X-Remote-User --enable-aggregator-routing=true
创建secret
kubectl create secret generic metrics-server-certs --from-file=metrics-server-key.pem --from-file=metrics-server.pem -n kube-system
修改metrics-server-deployment.yaml
