有rc在滚动升级之后,会造成服务访问中断,于是k8s引入了deployment资源

创建deployment

[root@k8s-master k8s_yaml]# cat deployment.yml 
apiVersion: extensions/v1beta1
kind: Deployment
metadata:
  name: nginx
spec:
  replicas: 3
  template:
    metadata:
      labels:
        app: nginx
    spec:
      containers:
      - name: nginx
        image: 10.0.0.11:5000/nginx:1.13
        ports:
        - containerPort: 80
 

 

deployment升级和回滚

命令行创建deployment

kubectl run nginx --image=10.0.0.11:5000/nginx:1.13 --replicas=3 --record

命令行升级版本

kubectl set image deployment nginx nginx=10.0.0.11:5000/nginx:1.15

查看deployment所有历史版本

kubectl rollout history deployment nginx

deployment回滚到上一个版本

kubectl rollout undo deployment nginx

deployment回滚到指定版本

kubectl rollout undo deployment nginx --to-revision=2

命令行升级：

[root@k8s-master k8s_yaml]# kubectl set image deployment nginx nginx=10.0.0.11:5000/nginx:1.15
 

命令行启动： --record记录操作命令

命令回滚：

指定版本回滚
