docker-compose 容器端口未显示在本地主机上

Question

我正在尝试运行一个 docker-compose 具有两项服务的应用程序。一个用于构建 Web 服务器，另一个用于运行测试。

docker-compose.yml

version: "3.7"
services:
  web:
    build: .
    ports:
      - "127.0.0.1:5000:5000"
    expose:
      - 5000
  test:
    # expose:
    #   - 5000
    depends_on: 
      - web
    build: test_python/.

./Dockerfile

FROM python:buster
RUN curl https://sh.rustup.rs -sSf | sh -s -- -y

# Add .cargo/bin to PATH
ENV PATH="/root/.cargo/bin:${PATH}"

# Check cargo is visible
RUN cargo --help
WORKDIR /code
COPY requirements.txt requirements.txt
RUN pip3 install -r  requirements.txt
EXPOSE 5000
COPY test_python .
CMD [ "python3", "base_routes.py" ]

test_python/Dockerfile

FROM python:buster
RUN pip3 install pytest requests
COPY . .

base_routes.py

from robyn import Robyn, static_file, jsonify
import asyncio

app = Robyn(__file__)

callCount = 0


@app.get("/")
async def h(request):
    print(request)
    global callCount
    callCount += 1
    message = "Called " + str(callCount) + " times"
    return message

@app.get("/test")
async def test(request):
    import os
    path = os.path.abspath(os.path.join(os.path.dirname(os.path.realpath(__file__)), "test_python/index.html"))
    return static_file(path)

@app.get("/jsonify")
async def json_get(request):
    return jsonify({"hello": "world"})


@app.post("/jsonify")
async def json(request):
    print(request)
    return jsonify({"hello": "world"})

@app.post("/post")
async def postreq(request):
    return bytearray(request["body"]).decode("utf-8")

@app.put("/put")
async def putreq(request):
    return bytearray(request["body"]).decode("utf-8")

@app.delete("/delete")
async def deletereq(request):
    return bytearray(request["body"]).decode("utf-8")

@app.patch("/patch")
async def patchreq(request):
    return bytearray(request["body"]).decode("utf-8")

@app.get("/sleep")
async def sleeper():
    await asyncio.sleep(5)
    return "sleep function"


@app.get("/blocker")
def blocker():
    import time
    time.sleep(10)
    return "blocker function"


if __name__ == "__main__":
    app.add_header("server", "robyn")
    app.add_directory(route="/test_dir",directory_path="./test_dir/build", index_file="index.html")
    app.start(port=5000)

这些是我在项目中使用的文件。当我尝试从我的机器打开 127.0.0.1:5000 时，它什么也没显示。但是，当我登录 web 容器并执行 curl http://localhost:5000/ 时，它给出了正确的响应。

我不知道如何在主机上访问它？

Answer 1

我必须让 python 服务器监听“0.0.0.0”。

我在代码库中添加了以下行

    app.start(port=5000, url='0.0.0.0')

docker-compose 容器端口未显示在本地主机上

docker-compose container port not showing up on localhost

python
