### 1、kube-scheduler部署 kube-scheduler是以插件形式存在的組件，正因為以插件形式存在，所以其具有可擴展可定制的特性。kube-scheduler相當于整個集群的調度決策者，其通過預選和優選兩個過程決定容器的最佳調度位置。 master http://127.0.0.1:8080 \\??kube-scheduler 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，入如果是交叉找apiserver，必須的配置SSL??client.pem?client-key.pem ``` vi /opt/kubernetes/server/bin/kube-scheduler.sh #!/bin/sh ./kube-scheduler \ --leader-elect \ --log-dir /data/logs/kubernetes/kube-scheduler \ --master http://127.0.0.1:8080 \ --v 2 ``` #### 創建日志目錄和授權 ``` mkdir -p /data/logs/kubernetes/kube-scheduler chmod +x /opt/kubernetes/server/bin/kube-scheduler.sh ``` 重啟守護進程配置 ``` vi /etc/supervisord.d/kube-scheduler.ini [program:kube-scheduler] command=/opt/kubernetes/server/bin/kube-scheduler.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-scheduler/scheduler.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 ``` supervisorctl update supervisorctl status ``` ### 2、檢查主控節點狀態 主控節點已經部署完畢，我們檢查集群健康狀態，用到kubectl ``` ln -s /opt/kubernetes/server/bin/kubectl /usr/bin/kubectl kubectl get cs ```
