【K8s+Docker技术全解】09.Master主控节点服务-部署controller-manager

## 99.151/152部署controller-manager ### 什么是controller-manager？ controller manager 译为“控制器管理器”，k8s内部有很多资源控制器，比如：Node Controller、Replication Controller、Deployment Controller、Job Controller、Endpoints Controller等等，为了降低复杂度，将这些控制切都编译成了一个可执行文件，并且在同一个进程中运行。 controller manager 负责维护集群的状态，比如故障检测、自动扩展、滚动更新等。 在99.151和99.152上部署controller-manager，这个不用签发证书。 ### 99.151部署controller-manager #### 创建启动脚本kube-controller-manager-startup.sh ```bash # 192.168.99.151 [root@k8s99-151 ~]# cd /opt/kubernetes/server/bin/ [root@k8s99-151 bin]# pwd /opt/kubernetes/server/bin [root@k8s99-151 bin]# mkdir -p /var/log/kube-controller-manager [root@k8s99-151 bin]# vim kube-controller-manager-startup.sh # 写入以下内容 #!/bin/bash ./kube-controller-manager \ --cluster-cidr 172.99.0.0/16 \ --leader-elect true \ --log-dir /var/log/kube-controller-manager \ --master http://127.0.0.1:8080 \ --service-account-private-key-file ./certs/ca-key.pem \ --service-cluster-ip-range 192.168.0.0/16 \ --root-ca-file ./certs/ca.pem \ --v 2 [root@k8s99-151 bin]# chmod +x kube-controller-manager-startup.sh # 测试启动 [root@k8s99-151 bin]# ./kube-controller-manager-startup.sh ``` #### 使用supervisor启动kube-controller-manager.ini ```bash [root@k8s99-151 bin]# vim /etc/supervisord.d/kube-controller-manager.ini ``` 添加下面内容 ```ini [program:kube-controller-manager-k8s99-151] command=/opt/kubernetes/server/bin/kube-controller-manager-startup.sh numprocs=1 directory=/opt/kubernetes/server/bin/ autostart=true autorestart=true startsecs=30 startretries=3 exitcodes=0,2 stopsignal=QUIT stopwaitsecs=10 user=root redirect_stderr=true stdout_logfile=/var/log/kube-controller-manager/controller.stdout.log stdout_logfile_maxbytes=64MB stdout_logfile_backups=4 stdout_capture_maxbytes=1MB stdout_events_enabled=false ``` 启动 ```bash [root@k8s99-151 bin]# supervisorctl update kube-controller-manager-k8s99-151: added process group [root@k8s99-151 bin]# supervisorctl status etcd-server-k8s99-151 RUNNING pid 1307, uptime 0:19:43 kube-apiserver-k8s99-151 RUNNING pid 1306, uptime 0:19:43 kube-controller-manager-k8s99-151 RUNNING pid 1708, uptime 0:00:37 ``` #### 检查controller-manager端口监听 ```bash [root@k8s99-151 bin]# netstat -luntp | grep kube-control tcp6 0 0 :::10252 :::* LISTEN 1709/./kube-control tcp6 0 0 :::10257 :::* LISTEN 1709/./kube-control ``` #### 防火墙允许对外端口 ```bash [root@k8s99-151 bin]# firewall-cmd --zone=public --add-port=10252/tcp --permanent success [root@k8s99-151 bin]# firewall-cmd --zone=public --add-port=10257/tcp --permanent success [root@k8s99-151 bin]# firewall-cmd --reload success ``` ### 99.152部署controller-manager 和99.151类似 ```bash # 192.168.99.152 cd /opt/kubernetes/server/bin/ mkdir -p /var/log/kube-controller-manager # 创建启动文件 cat > kube-controller-manager-startup.sh << EOF #!/bin/bash ./kube-controller-manager \ --cluster-cidr 172.99.0.0/16 \ --leader-elect true \ --log-dir /var/log/kube-controller-manager \ --master http://127.0.0.1:8080 \ --service-account-private-key-file ./certs/ca-key.pem \ --service-cluster-ip-range 192.168.0.0/16 \ --root-ca-file ./certs/ca.pem \ --v 2 EOF # 添加执行权限并测试 chmod +x kube-controller-manager-startup.sh ./kube-controller-manager-startup.sh # 创建supervisor启动配置 cat > /etc/supervisord.d/kube-controller-manager.ini << EOF [program:kube-controller-manager-k8s99-152] command=/opt/kubernetes/server/bin/kube-controller-manager-startup.sh numprocs=1 directory=/opt/kubernetes/server/bin/ autostart=true autorestart=true startsecs=30 startretries=3 exitcodes=0,2 stopsignal=QUIT stopwaitsecs=10 user=root redirect_stderr=true stdout_logfile=/var/log/kube-controller-manager/controller.stdout.log stdout_logfile_maxbytes=64MB stdout_logfile_backups=4 stdout_capture_maxbytes=1MB stdout_events_enabled=false EOF # supervisor启动归并查看端口 supervisorctl update supervisorctl status netstat -luntp | grep kube-control # 防火墙允许端口 firewall-cmd --zone=public --add-port=10252/tcp --permanent firewall-cmd --zone=public --add-port=10257/tcp --permanent firewall-cmd --reload ```
