7. k8s二进制集群之Kube ApiServer部署

继续上一篇文章《k8s二进制集群之各节点部署》下面介绍一下各节点的部署与配置。

创建kube工作目录（仅在主节点上创建即可）

mkdir -p /etc/kubernetes/
mkdir -p /etc/kubernetes/ssl
mkdir -p /var/log/kubernetes

同样在我们的部署主机上创建apiserver证书请求文件

需要替换成你自己的节点ip和证书信息

cat > kube-apiserver-csr.json <<"EOF"
{"CN": "kubernetes","hosts": ["127.0.0.1","192.168.3.41","192.168.3.42","192.168.3.43","192.168.3.100","10.96.0.1","kubernetes","kubernetes.default","kubernetes.default.svc","kubernetes.default.svc.cluster","kubernetes.default.svc.cluster.local"],"key": {"algo": "rsa","size": 2048},"names": [{"C":"CN","ST":"zhejiang","L":"hangzhou","O":"eyinfo","OU":"CN"}]
}
EOF

根据证书文件生成apiserver证书

cfssl gencert -ca=ca.pem -ca-key=ca-key.pem -config=ca-config.json -profile=kubernetes kube-apiserver-csr.json | cfssljson -bare kube-apiserver
