amazon-web-services - 使用来自 docker 镜像的 lambda 的 aws localstack，调用时出错错误 : No such container:

标签 amazon-web-services docker aws-lambda localstack

我正在努力让 localstack 与 lambda 一起使用，希望这里有人可以帮助我。

在我的机器上: -Windows 10 -Docker桌面

我构建了一个简单的 python 3.8 应用程序，它将地址作为事件负载，并返回一些 GPS 数据。

  • 当尝试在 Docker 中本地运行它并通过 API 调用它时 --> 有效
  • 当我尝试将其作为 Docker 镜像部署到云 Lambda 中时 --> 它可以工作

所以我想在本地拥有一个开发环境并尝试使用 localstack image

我用这样的组合构建我的堆栈。

 version: '3.3'
services:
  localstack:
    image: localstack/localstack:0.12.15
    ports:
      - "53:53"
      - "443:443"
      - "4566-4583:4566-4583"
    environment:
      - DATA_DIR=/tmp/localstack/data
      - DEBUG=1
      - DEFAULT_REGION=eu-west-1
      - DOCKER_HOST=unix:///var/run/docker.sock
      - LAMBDA_EXECUTOR=docker
      - LAMBDA_REMOVE_CONTAINERS=true
      - LAMBDA_REMOTE_DOCKER=true
      - SERVICES=lambda,s3
    volumes:
      - "/var/run/docker.sock:/var/run/docker.sock"
      - "E:/Sources/container_Lambda/storage_localstack:/tmp/localstack"
    networks:
      - localstacknet
  
  test-lambda:
    image: tes-lambda1:latest
    build:
      context: ./
    networks :
      - localstacknet
networks:
  localstacknet:
    external: false
    driver : bridge
    name: localstacknet

启动时 https://localhost:4566/health healthcheck 很好

  "services": {
    "lambda": "running",
    "logs": "running",
    "s3": "running",
    "cloudwatch": "running"
  },
  "features": {
    "persistence": "initialized",
    "initScripts": "initialized"
  }
}

现在我使用以下命令创建 lambda 函数

aws --endpoint-url http://localhost:4566 lambda create-function --function-name test-lambda --code ImageUri=tes-lambda1:latest --role arn:aws:iam::000000000:role/lambda-ex

这让我获得了成功的创作

{
    "FunctionName": "test-lambda",
    "FunctionArn": "arn:aws:lambda:eu-west-1:000000000000:function:test-lambda",
    "Role": "arn:aws:iam::000000000:role/lambda-ex",
    "Handler": "handler.handler",
    "Description": "",
    "Timeout": 3,
    "LastModified": "2021-08-11T08:23:32.406+0000",
    "Version": "$LATEST",
    "VpcConfig": {},
    "TracingConfig": {
        "Mode": "PassThrough"
    },
    "RevisionId": "50455ed8-737d-4e79-a6ab-93bd31b89d0d",
    "State": "Active",
    "LastUpdateStatus": "Successful",
    "PackageType": "Zip"
}

但是当我想调用我的 lambda 时

aws --endpoint-url http://localhost:4566 lambda invoke --function-name arn:aws:lambda:eu-west-1:000000000000:function:test-lambda response.json

我收到以下回复

{
    "StatusCode": 200,
    "FunctionError": "Unhandled",
    "LogResult": "",
    "ExecutedVersion": "$LATEST"
}

并将跟踪日志记录到 localstack 容器提示符中，如下所示。

真的希望得到一些帮助才能使其发挥作用。 非常感谢

最佳答案

更新: 我终于找到了解决容器丢失问题的方法。 您必须将特权:true 添加到您的组合中，以便允许本地堆栈生成新容器。 我仍然遇到问题，但出现错误:没有这样的容器:已解决

我的 docker compose 现在就像

version: '3.3'
services:
  localstack:
    image: localstack/localstack:0.12.15
    
    ports:
      - "53:53"
      - "443:443"
      - "4566-4583:4566-4583"
    environment:
      - DATA_DIR=/tmp/localstack/data
      - DEBUG=1
      - DEFAULT_REGION=eu-west-1
      - DOCKER_HOST=unix:///var/run/docker.sock
      - HOST_TMP_FOLDER= E:/Sources/container_Lambda/storage_localstack
      - LAMBDA_EXECUTOR=docker-reuse
      - LAMBDA_REMOVE_CONTAINERS=true
      - LAMBDA_REMOTE_DOCKER=false
      - SERVICES=lambda,s3,iam,cloudwatch,dynamodb
    volumes:
      - "/var/run/docker.sock:/var/run/docker.sock"
      - "E:/Sources/container_Lambda/storage_localstack/TMP:/tmp/localstack"
    networks:
      - localstacknet
    
    privileged: true
  
networks:
  localstacknet:
    external: false
    driver : bridge
    name: localstacknet

我的新问题是这样的。
