我已经推送了 lambda 函数，正如我在 localstack 中看到的那样，基于以下命令/输出

 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，我收到一个错误，我的 localstack 正在一个 docker 容器中运行

aws --endpoint-url= http://localhost:4574 lambda 调用 --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):

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 是编写的Go，当我在真正的 AWS 上手动执行它时，它工作得很好。

LAMBDA_EXECUTOR=docker您应该使用传递的环境和/var/run/docker.sock:/var/run/docker.sock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
