AWS SNS/SQS

关于AWS SNS/SQS pubsub组件的详细文档

配置

要为 发布/订阅设置 AWS SNS/SQS,您需要创建一个类型为 pubsub.snssqs 的组件。 See this guide on how to create and apply a pubsub configuration.

apiVersion: dapr.io/v1alpha1
kind: Component
metadata:
  name: snssqs-pubsub
  namespace: default
spec:
  type: pubsub.snssqs
  version: v1
  metadata:
    - name: accessKey
      value: "AKIAIOSFODNN7EXAMPLE"
    - name: secretKey
      value: "wJalrXUtnFEMI/K7MDENG/bPxRfiCYEXAMPLEKEY"
    - name: region
      value: "us-east-1"
    - name: sessionToken
      value: "TOKEN"
    - name: messageVisibilityTimeout
      value: 10
    - name: messageRetryLimit
      value: 10
    - name: messageWaitTimeSeconds
      value: 1
    - name: messageMaxNumber
      value: 10

元数据字段规范

字段 必填 详情 Example
accessKey Y 具有SNS和SQS适当权限的AWS账户的ID。 可以用secretKeyRef来引用密钥。 "AKIAIOSFODNN7EXAMPLE"
secretKey Y AWS用户的密钥。 可以用secretKeyRef来引用密钥。 "wJalrXUtnFEMI/K7MDENG/bPxRfiCYEXAMPLEKEY"
region Y AWS区域到实例。 有效区域请参见本页面:https://docs.aws.amazon.com/AmazonRDS/latest/UserGuide/Concepts.RegionsAndAvailabilityZones.html。 确保该地区有SNS和SQS。 "us-east-1"
终结点 N 该组件要使用的AWS端点, 仅用于本地开发。 仅用于本地开发。 当对生产环境的AWS,endpoint是不需要的。 "http://localhost:4566"
sessionToken N 要使用的 AWS 会话令牌。 只有当您使用临时安全凭证时才需要会话令牌。 "TOKEN"
messageVisibilityTimeout N 消息发送至订阅者后,隐藏接收请求的时间,以秒为单位。 默认值:10 10
messageRetryLimit N 在处理消息失败后,从队列中删除该消息之前,重新发送消息的次数。 默认值:10 10
messageWaitTimeSeconds N 等待收到消息后再提出请求的时间 默认值:1 1
messageMaxNumber N 每次从队列中接收消息的最大数量。 默认值:10,最大值:10 10

创建SNS/SQS实例


对于本地开发来说,可以用localstack项目集成AWS SNS/SQS。 按照这里的说明安装localstack CLI。

In order to use localstack with your pubsub binding, you need to provide the endpoint configuration in the component metadata. 当在AWS生产环境上运行时,endpoint是不需要的。

See Authenticating to AWS for information about authentication-related attributes

apiVersion: dapr.io/v1alpha1
kind: Component
metadata:
  name: snssqs-pubsub
spec:
  type: pubsub.snssqs
  version: v1
  metadata:
    - name: endpoint
      value: http://localhost:4566
    # Use us-east-1 for localstack
    - name: region
      value: us-east-1

要在Kubernetes上运行localstack,可以应用以下配置。 Localstack is then reachable at the DNS name http://localstack.default.svc.cluster.local:4566 (assuming this was applied to the default namespace) and this should be used as the endpoint

apiVersion: apps/v1
kind: Deployment
metadata:
  name: localstack
  namespace: default
spec:
  # using the selector, we will expose the running deployments
  # this is how Kubernetes knows, that a given service belongs to a deployment
  selector:
    matchLabels:
      app: localstack
  replicas: 1
  template:
    metadata:
      labels:
        app: localstack
    spec:
      containers:
      - name: localstack
        image: localstack/localstack:latest
        ports:
          # Expose the edge endpoint
          - containerPort: 4566
---
kind: Service
apiVersion: v1
metadata:
  name: localstack
  labels:
    app: localstack
spec:
  selector:
    app: localstack
  ports:
  - protocol: TCP
    port: 4566
    targetPort: 4566
  type: LoadBalancer

为了在AWS中运行,你应该创建一个具有SNS和SQS服务权限的IAM用户。 使用AWS account IDAWS account secret,并使用Kubernetes密钥和secretKeyRef将它们插入组件元数据中的accessKeysecretKey
