K8S集群安装 之 安装部署controller-manager

Posted 2021-03-12

一、在两个nodes节点上安装controller-manager服务

# 221/222机器：
bin]# vi /opt/kubernetes/server/bin/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

bin]# chmod +x /opt/kubernetes/server/bin/kube-controller-manager.sh
bin]# mkdir -p /data/logs/kubernetes/kube-controller-manager
# 注意22机器，下面要改成7-22，一处修改
bin]# vi /etc/supervisord.d/kube-conntroller-manager.ini
