文件：

# main.py:
from fastapi import FastAPI

app = FastAPI()

@app.get("/")
def read_root():
    return {"Hello": "World"}

-

# nginx.conf:
events {
    worker_connections 128;
}
http{
    server {
        listen 0.0.0.0:8080;
        location / {
            include uwsgi_params;
            uwsgi_pass unix:/tmp/uvi.sock;
        }
    }
}

-

# Dockerfile
FROM python:3

COPY main.py .

RUN apt-get -y update && apt-get install -y htop tmux vim nginx

RUN pip install fastapi uvicorn

COPY nginx.conf /etc/nginx/

设定：

docker build -t nginx-uvicorn:latest .
docker run -it --entrypoint=/bin/bash --name nginx-uvicorn -p 80:8080 nginx-uvicorn:latest

开始uvicorn像往常一样：

$ uvicorn --host 0.0.0.0 --port 8080 main:app

工程 - 我可以从我的浏览器访问http://127.0.0.1/。

启动uvicorn背后nginx：

$ service nginx start
[ ok ] Starting nginx: nginx.

$ uvicorn main:app --uds /tmp/uvi.sock
INFO:     Started server process [40]
INFO:     Uvicorn running on unix socket /tmp/uvi.sock (Press CTRL+C to quit)
INFO:     Waiting for application startup.
INFO:     Application startup complete.

如果我现在要求http://127.0.0.1/则：

• Nginx：响应以502网关错误
• uvicorn：会回应WARNING: Invalid HTTP request received.

因此，建立一个连接，但事情是错的配置。

有任何想法吗？
