### controller-manager部署： Controller Manager作為集群內部的管理控制中心，負責集群內的Node、Pod副本、服務端點（Endpoint）、命名空間（Namespace）、服務賬號（ServiceAccount）、資源定額（ResourceQuota）的管理，當某個Node意外宕機時，Controller Manager會及時發現并執行自動化修復流程，確保集群始終處于預期的工作狀態。 controller-manager 設置為只調用當前機器的 apiserver，走127.0.0.1網卡，因此不配制SSL證書 ``` # 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 ``` #### 創建日志目錄 ``` mkdir -p /data/logs/kubernetes/kube-controller-manager chmod +x /opt/kubernetes/server/bin/kube-controller-manager.sh ``` #### 配置文件： ``` vi /etc/supervisord.d/kube-conntroller-manager.ini [program:kube-controller-manager] command=/opt/kubernetes/server/bin/kube-controller-manager.sh ; the program (relative uses PATH, can take args) numprocs=1 ; number of processes copies to start (def 1) directory=/opt/kubernetes/server/bin ; directory to cwd to before exec (def no cwd) autostart=true ; start at supervisord start (default: true) autorestart=true ; retstart at unexpected quit (default: true) startsecs=30 ; number of secs prog must stay running (def. 1) startretries=3 ; max # of serial start failures (default 3) exitcodes=0,2 ; 'expected' exit codes for process (default 0,2) stopsignal=QUIT ; signal used to kill process (default TERM) stopwaitsecs=10 ; max num secs to wait b4 SIGKILL (default 10) user=root ; setuid to this UNIX account to run the program redirect_stderr=true ; redirect proc stderr to stdout (default false) stdout_logfile=/data/logs/kubernetes/kube-controller-manager/controller.stdout.log ; stderr log path, NONE for none; default AUTO stdout_logfile_maxbytes=64MB ; max # logfile bytes b4 rotation (default 50MB) stdout_logfile_backups=4 ; # of stdout logfile backups (default 10) stdout_capture_maxbytes=1MB ; number of bytes in 'capturemode' (default 0) stdout_events_enabled=false ; emit events on stdout writes (default false) ``` #### 更新配置查看啟動情況 ``` supervisorctl update supervisorctl status ```
