我无法使用 localstack 12.5 lambda（在 4566 端口运行）调用在 localhost:9090 上运行的另一个容器中的 rest api

Question

localstack 12.5

dummy.py file for lambda hanlder

import sys
import requests

def handler(event, context):
    print("Inside handler")
    x = requests.get('http://localhost:9090/ping')
    print(x.status_code)
    return str(x.content)

In handler when i am calling get api which is in another container i am getting connection refused error.

Error: "ConnectionError","errorMessage":"HTTPConnectionPool(host='localhost', port=9090): Max retries exceeded with url: Caused by NewConnectionError('\ : Failed to establish a new connection:

However with postman I am able to hit http://localhost:9090/ping API

Also If I replace x = requests.get('https://w3schools.com') then I am getting 200 .

Answer 1

The issue has been resolved by adding below env variable in localstack

LAMBDA_DOCKER_NETWORK="host"
