技術標籤:K8Skuberneteslinux

安裝部署主控節點控制器/排程器服務

叢集規劃

主機名		                	角色				ip
hdss-1-21.host.com		controller-manager		192.168.1.21
hdss-1-22.host.com		controller-manager		192.168.1.22

注意:這裡部署文件以hdss-1-22.host.com主機為例,另外一臺運算節點安裝部署方法類似

編輯kube-controller-manager.sh執行指令碼

建立指令碼中的目錄

[[email protected] bin]# mkdir -p /data/logs/kubernetes/kube-controller-manager
[[email protected] bin]# chmod +x /opt/kubernetes/server/bin/kube-controller-manager.sh

編輯用於supervisord後臺啟動配置檔案 kube-conntroller-manager.ini
