Kubernetes - 滚动升级

Deployment类型的Pod使用“kubectl set”滚动升级

Example:

apiVersion: apps/v1beta1
kind: Deployment
metadata:
  name: nginx-deployment
spec:
  replicas: 3
  template:
    metadata:
      labels:
        app: nginx
    spec:
      containers:
      - name: nginx
        image: nginx:1.7.9
        ports:
        - containerPort: 80

升级到指定镜像:

$ kubectl set image deployment/nginx-deployment nginx=nginx:1.91
deployment "nginx-deployment" image updated

回滚：

kubectl rollout undo deployment/topka-cn
