"local" Step Functions 状态机在主机上调用 moto_server 时出现 404 错误

Question

在“本地”模式下使用 AWS Step Functions 状态机 (SFSM)，即在我的笔记本电脑 Docker 中运行ning

正在尝试运行一个指向我笔记本电脑主机上模拟服务的任务

我可以在 Docker 上正确安装 SFSM，更新它，运行它

aws stepfunctions --endpoint http://localhost:8083 create-state-machine \
    --definition file://src/my_sfn.json \
    --role-arn 'arn:aws:iam::ACCTNUM:role/DummyRole' \
    --name my_sfn

我可以从 docker 运行 curl http://host.docker.internal:5000 连接到 moto_server

我在 SFSM 容器上安装了 aws cli，运行 aws sns --endpoint http://host.docker.internal:5000 list-topics 它显示了正确的主题

我在我的 docker env 文件中设置 SNS_ENDPOINT url 以指向主机

但是如果运行使用 SFSM:

我总是会收到 404 Not Found 错误

my_sfn.json:

{
    "StartAt": "step1",
    "States": {
        "step1": {
            "Type": "Task",
            "Resource": "arn:aws:states:::sns:publish",
            "Parameters":{
                "Message":{"Input":"howdy"},
                "TopicArn":"arn:aws:sns:us-west-2:ACCTNUM:foo"
            },
            "End": true
        }
    }
}

docker-env.txt:

SNS_ENDPOINT=http://host.docker.internal:5000

知道如何解决吗？

Answer 1

看来我必须向环境文件添加更多信息：

AWS_ACCOUNT_ID=123456789012
AWS_ACCESS_KEY_ID=AAAAAAAAAAAAAAAA
AWS_SECRET_ACCESS_KEY=AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA
AWS_DEFAULT_REGION=us-west-2

始终使用相同的帐户 ID 和区域，并且有效
