从 Docker 连接到本地主机（Java 应用程序使用 mocking AWS 的 localstack）

Question

I am using localstack to mock AWS resources locally. This works fine when I run my application from the IDE. I have a dockerfile which contains the following (1338 is the port this app would run on)

ADD target/myapp-0.0.1-SNAPSHOT.jar app.jar

and I have a script to run which is

#!/bin/bash
set -e # Stop on errors

mvn clean package

docker build -t myapp .

docker run -it --name myapp -p 1338:1338 --rm myapp:latest

So when I run I get the error

Unexpected error occurred in scheduled task
com.amazonaws.SdkClientException: Unable to execute HTTP request: Connect to localhost:4575 [localhost/127.0.0.1] failed: Connection refused (Connection refused)

Answer 1

I suppose you're running localstack on your host OS, that's why the myapp unable to reach it. To solve your issue, you need adjust your docker run instruction by adding parameter --network host .
