(1)在跳板机上下载master组件下载地址:https://dl.k8s.io/v1.9.6/kubernetes-server-linux-amd64.tar.gz
cd /tools/
tar xf kubernetes-server-linux-amd64.tar.gz
(2)在跳板机上生成master证书
#cd /temp/ssl
cat >k8s-csr.json <<EOF
{
"CN": "kubernetes",
"hosts": [
"127.0.0.1",
"192.168.19.128",
"10.254.0.1",
"kubernetes",
"kubernetes.default",
"kubernetes.default.svc",
"kubernetes.default.svc.cluster",
"kubernetes.default.svc.cluster.local"
],
"key": {
"algo": "rsa",
"size": 2048
},
"names": [
{
"C": "CN",
"ST": "Hangzhou",
"L": "Hangzhou",
"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 k8s-csr.json | cfssljson -bare kubernetes
