无法通过aws cli从localstack调用lambda函数

Question

根据下面的命令/输出，我在localstack中看到了lambda函数

 aws lambda get-function --function-name books1 --endpoint-url=http://localhost:4574
{
    "Code": {
        "Location": "http://localhost:4574/2015-03-31/functions/books1/code"
    }, 
    "Configuration": {
        "Version": "$LATEST", 
        "FunctionName": "books1", 
        "CodeSize": 50, 
        "FunctionArn": "arn:aws:lambda:us-east-1:000000000000:function:books1", 
        "Environment": {}, 
        "Handler": "main", 
        "Runtime": "go1.x"
    }
}

当我尝试执行它时，如下所示，我得到一个错误，我的localstack正在docker容器内运行

AWS-Endpoint-url=http://localhost:4574 lambda invoke-function-name books1/tmp/output.json

An error occurred (InternalFailure) when calling the Invoke operation (reached max retries: 4): Error executing Lambda function: Unable to find executor for Lambda function "books1". Note that Node.js and .NET Core Lambdas currently require LAMBDA_EXECUTOR=docker Traceback (most recent call last):

    event, context=context, version=version, asynchronous=asynchronous)

    result = lambda_function(event, context)
  File "/opt/code/localstack/localstack/services/awslambda/lambda_api.py", line 390, in generic_handler

Exception: Unable to find executor for Lambda function "books1". Note that Node.js and .NET Core Lambdas currently require LAMBDA_EXECUTOR=docker

这个lambda是用go编写的，当我在真正的AWS上手动执行它时，它工作得很好。

您应该使用传递的lambda_executor=docker环境和/var/run/docker.sock:/code>卷运行localstack容器

docker run \
  -itd \
  -v /var/run/docker.sock:/var/run/docker.sock \
  -e LAMBDA_EXECUTOR=docker \
  -p 4567-4583:4567-4583 -p 8080:8080 \
  --name localstack \
  localstack/localstack
