YAML配置文件管理对象

对象管理：

# 创建deployment资源

kubectl create -f nginx-deployment.yaml

# 查看deployment

kubectl get deploy

# 查看ReplicaSet

kubectl get rs

# 查看pods所有标签

kubectl get pods --show-labels

# 根据标签查看pods

kubectl get pods -l app=nginx

# 滚动更新镜像

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

# 实时观察发布状态：

kubectl rollout status deployment/nginx-deployment

# 查看deployment历史修订版本

kubectl rollout history deployment/nginx-deployment

kubectl rollout history deployment/nginx-deployment --revision=3

# 回滚到以前版本

kubectl rollout undo deployment/nginx-deployment

kubectl rollout undo deployment/nginx-deployment --to-revision=3

# 扩容deployment的Pod副本数量

kubectl scale deployment nginx-deployment --replicas=10

# 设置启动扩容/缩容

kubectl autoscale deployment nginx-deployment --min=10 --max=15 --cpu-percent=80
