docker compose网络不服务主机的请求

Question

[docker-compose question]

你好!我已经被困在这个问题上一段时间了，所以希望我们能一起调试。

我使用docker compose来启动三个独立的服务。一切都是伟大的。应用健康检查通过，服务相互联系，但我似乎无法从主机上curl我的应用。

我为app.ports尝试了以下值:

"127.0.0.1:3000:3000"3000:3000"0.0.0.0:3000:3000">

我也试过用"host"但这似乎也不起作用，我不喜欢它，因为很明显Mac不支持，我的本地开发环境是Macosx。prod服务器是ubuntu。

我已经尝试明确定义默认的桥接网络:

networks:
default:
driver: bridge

这是我的docker-compose.yml

version: "2.4"
services:
rabbitmq:
image: rabbitmq
volumes:
- ${ML_FILE_PATH}/taskqueue/config/:/etc/rabbitmq/
environment:
LC_ALL: "C.UTF-8"
LANG: "C.UTF-8"
celery-worker:
image: ${ML_IMAGE_NAME}
entrypoint: "celery --broker='amqp://<user>:<password>@rabbitmq:5672//' -A taskqueue.celeryapp worker --uid 1111"
runtime: ${RUNTIME}  ## either "runc" if running locally on debug mode or "nvidia" on production with multi processors
volumes:
- ${ML_FILE_PATH}:/host
depends_on:
- rabbitmq
- app

我可以像预期的那样从容器内访问服务。

我不知道我错过了什么。非常感谢你的帮助!

Answer 1

我不确定，但我认为你不能路由流量从主机到mac osx上的容器

Answer 2

这最终与docker-compose无关。

我的flask应用程序在127.0.0.1上启动。我需要以一种外部可见服务器。

我只需要在我的开始脚本中添加——host=0.0.0.0。
