阿里云容器服务

开通容器服务

开通前

开通并创建集群后(这里使用按量付费的ECS机器，测试后即可释放)

配置节点完成后

配置无状态应用

一开始我是直接使用的 yaml 进行创建

apiVersion: apps/v1
kind: Deployment
metadata:
  labels:
    app: nginx
  name: nginx-deployment-basic
  namespace: default
spec:
  progressDeadlineSeconds: 600
  replicas: 1
  revisionHistoryLimit: 10
  selector:
    matchLabels:
      app: nginx
  strategy:
    rollingUpdate:
      maxSurge: 25%
      maxUnavailable: 25%
    type: RollingUpdate
  template:
    metadata:
      labels:
        app: nginx
    spec:
      containers:
        - image: 'nginx:1.7.9'
          imagePullPolicy: IfNotPresent
          name: nginx
          ports:
            - containerPort: 80
              protocol: TCP
          readinessProbe:
            failureThreshold: 3
            httpGet:
              path: /
              port: 80
              scheme: HTTP
            initialDelaySeconds: 10
            periodSeconds: 10
            successThreshold: 1
            timeoutSeconds: 1
          resources: {}
          terminationMessagePath: /dev/termination-log
          terminationMessagePolicy: File
      dnsPolicy: ClusterFirst
      restartPolicy: Always
      schedulerName: default-scheduler
      securityContext: {}
      terminationGracePeriodSeconds: 30

结果是 failure , 因为我是VPC网络并且没有开通SLB和弹性IP，所以拉不下来镜像.

开通NAT网关

开通需要在NAT网关上添加SNAT条目，绑定ECS/交换机走NAT网关的流量进出

绑定时发现需要先申请弹性IP.

开通弹性IP&弹性IP绑定NAT网关
