|NO.Z.00031|——————————|^^ 部署 ^^|——|KuberNetes&二进制部署.V09|5台Server|——|kubernetes-master|kube-controller-manager|

一、kube-ControllerManager组件部署

### --- kube-controller-manager

~~~     所有Master节点配置kube-controller-manager service
~~~     # 注意本文档使用的k8s Pod网段为172.16.0.0/12，
~~~     # 该网段不能和宿主机的网段、k8s Service网段的重复，请按需修改

二、创建kube-controller-manager配置文件

### --- 所有节点创建kube-controller-manager配置文件

[root@k8s-master01 ~]# cat /usr/lib/systemd/system/kube-controller-manager.service
[Unit]
Description=Kubernetes Controller Manager
Documentation=https://github.com/kubernetes/kubernetes
After=network.target

[Service]
ExecStart=/usr/local/bin/kube-controller-manager \
      --v=2 \
      --logtostderr=true \
      --address=127.0.0.1 \
      --root-ca-file=/etc/kubernetes/pki/ca.pem \
      --cluster-signing-cert-file=/etc/kubernetes/pki/ca.pem \
      --cluster-signing-key-file=/etc/kubernetes/pki/ca-key.pem \
      --service-account-private-key-file=/etc/kubernetes/pki/sa.key \
      --kubeconfig=/etc/kubernetes/controller-manager.kubeconfig \
      --leader-elect=true \
      --use-service-account-credentials=true \
      --node-monitor-grace-period=40s \
      --node-monitor-period=5s \
      --pod-eviction-timeout=2m0s \
      --controllers=*,bootstrapsigner,tokencleaner \
      --allocate-node-cidrs=true \
      --cluster-cidr=172.16.0.0/12 \
      --requestheader-client-ca-file=/etc/kubernetes/pki/front-proxy-ca.pem \
      --node-cidr-mask-size=24
      
Restart=always
RestartSec=10s

[Install]
WantedBy=multi-user.target

三、启动kube-controllermanager

### --- 启动kube-controller-manager

[root@k8s-master01 ~]#  systemctl daemon-reload
[root@k8s-master01 ~]# systemctl enable --now kube-controller-manager
Created symlink from /etc/systemd/system/multi-user.target.wants/kube-controller-manager.service to /usr/lib/systemd/system/kube-controller-manager.service.

四、查看kube-controller-manager状态

### --- 查看kube-controller-manager状态

[root@k8s-master01 ~]# systemctl status kube-controller-manager
  Active: active (running) since Wed 2021-05-12 20:34:49 CST; 24s ago
