### k8s主控节点-controller-manager ###

#### 启动脚本 ####

`vi /opt/kubernetes/server/bin/kube-controller-manager.sh`

#!/bin/sh
    ./kube-controller-manager \
      --allocate-node-cidrs true \ # 配合cluster-cidr一起作用
      --cluster-cidr 172.20.0.0/16 \
      --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

对于 kube-controller-manager，`cluster-cidr` 需要在 `allocate-node-cidrs` 参数设置为 true 时才能联合发挥作用，主要用于为没有设置 Spec.PodCIDR 的 Node 节点配置 PodCIDR 地址，这个属性在某些场景下能帮助节点完成网络相关的设置工作。

`chmod +x /opt/kubernetes/server/bin/kube-controller-manager.sh`  
`mkdir -p /data/logs/kubernetes/kube-controller-manager`
