错误：指定网络模式“awsvpc”时必须提供网络配置

Question

我有这个任务定义代码，有问题：

{
  "family": "ikg-api",
  "taskRoleArn": "",
  "executionRoleArn": "arn:aws:iam::913xxxx371:role/ecsTaskExecutionRole",
  "networkMode": "awsvpc",

        }
      ],
      "essential": true,
      "environment": [
        {
          "name": "is_docker",
          "value": "yes"
        }
      ],
      "secrets": [
        {

    }
  ]
}

当我使用以下方式上传定义时：

---

aws ecs run-task --cluster tutorial --task-definition ikg-api:1  --count 1

---

我收到此错误：

调用RunTask时发生错误（InvalidParameterException） 操作：网络模式时必须提供网络配置 指定了“awsvpc”。

---

我一生都不知道如何解决它。我尝试为我能找到的网络配置设置最理智的值...没有骰子。 有人知道我如何解决这个问题吗？

Answer 1

这是包含网络配置的运行任务命令

aws ecs run-task --cluster your-cluster --task-definition your-task:1 
     --count 1 --launch-type FARGATE 
     --network-configuration "awsvpcConfiguration={subnets=[subnet-0123456789],securityGroups=[sg-0123456789]}"

Answer 2

您将需要类似下面的东西（我工作中的快照）

NetworkConfiguration:
    AwsvpcConfiguration:
      AssignPublicIp: DISABLED
      SecurityGroups:
      - !Ref ECSServicesSecurityGroup
      Subnets:
      - Fn::ImportValue: !Sub ${VPCStack}-SubnetPrivateA
      - Fn::ImportValue: !Sub ${VPCStack}-SubnetPrivateB
      - Fn::ImportValue: !Sub ${VPCStack}-SubnetPrivateC

Answer 3

我认为@user2014363的答案是正确的，我能够用它来运行我的任务。如果其他人尝试在 CI 中执行此操作，您可能无法提前知道您的子网/安全组 ID。我能够使用 AWS CLI 来获取这些（您需要有某种方法来识别所需的子网/安全组，例如按标签进行过滤）：

mytask: 
  image: python:3.8
  stage: deploy
  only:
    - master
  when: manual
  before_script:
    - pip install awscli
    - apt-get -qq update && apt-get -y install jq
    - |
      subnets=$( \
        aws ec2 describe-subnets \
          --filters \
            Name=tag:aws:cloudformation:stack-name,Values=${ENVIRONMENT}-${APP_NAME}-stack \
            Name=tag:aws-cdk:subnet-type,Values=Public \
        | jq -r '.Subnets | map(.SubnetId) | join(",")')
  script:
    - |
      aws ecs run-task \
        --cluster ${ENVIRONMENT}-${APP_NAME}-cluster \
        --task-definition ${ENVIRONMENT}-${APP_NAME}-collectstatic \
        --network-configuration "awsvpcConfiguration={subnets=[${subnets}],assignPublicIp=ENABLED}" \
        --count 1 \
        --launch-type FARGATE

Answer 4

对于使用 Terraform 的用户，您需要在“aws_ecs_service”资源中添加 network_configuration 块。

network_configuration {
  subnets         = aws_subnet.private.*.id
}
