YAML配置文件管理對象
對象管理：
# 創建deployment資源
kubectl create -f nginx-deployment.yaml
# 查看deployment
kubectl get deploy
# 查看ReplicaSet
kubectl get rs
# 查看pods所有標簽
kubectl get pods --show-labels
# 根據標簽查看pods
kubectl get pods -l app=nginx
# 滾動更新鏡像
kubectl set image deployment/nginx-deployment nginx=nginx:1.11
或者
kubectl edit deployment
 
/nginx-deployment
或者
kubectl apply -f nginx-deployment.yaml
# 實時觀察發布狀態：
kubectl rollout status deployment/nginx-deployment
# 查看deployment歷史修訂版本
kubectl rollout history deployment/nginx-deployment
kubectl rollout history deployment/nginx-deployment --revision=3
# 回滾到以前版本
kubectl rollout undo deployment/nginx-deployment
kubectl rollout undo deployment
 
/nginx-deployment --to-revision=3
# 擴容deployment的Pod副本數量
kubectl scale deployment nginx-deployment --replicas=10
# 設置啟動擴容/縮容
kubectl autoscale deployment nginx-deployment --min=10 --max=15 --cpu-percent=80

發布服務：
# cat nginx-service.yaml
apiVersion: v1
kind: Service
metadata:
name: nginx-service
labels:
app: nginx
spec:
ports:
 
- port: 88
targetPort: 80
selector:
app: nginx
清理：
# kubectl delete -f nginx-deployment.yaml
# kubectl delete -f nginx-service.yaml
