K8S 二进制安装部署_09_部署主控节点控制器-调度器

在 10.4.7.21 10.4.7.22 上面部署
kube-controller-manager kube-scheduler 不需要签发证书
kube-apiserver
kube-controller-manager kube-scheduler 这三个组件部署在同一台服务器上，kube-controller-manager kube-scheduler 找本机的 apiserver 是可以直接走http 协议，不需要证书。如果 apiserver 和这两个组件没有部署在同一台服务器上，这时这两个组件与apiserver通信，也还是需要签发client证书的。

部署kube-controller-manager

创建启动脚本：
cd /opt/kubernetes/server/bin/
vim kube-controller-manager.sh
#!/bin/sh
./kube-controller-manager \
--cluster-cidr 172.7.0.0/16 \
--leader-elect true \
--log-dir /data/logs/kubernetes/kube-controller-manager \
--master http://127.0.0.1:8080 \
--service-account-private-key-file ./cert/ca-key.pem \
--service-cluster-ip-range 192.168.0.0/16 \
--root-ca-file ./cert/ca.pem \
--v 2
