React在Docker上运行

发布于 2025-02-10 16:39:39 字数 14309 浏览 2 评论 0原文

基本上，我正在使用此堆栈进行WebApp： 后端：取决于数据库的FastApi（Python） 数据库：MySQL（通过Python-Connector连接） Frontend: React Functional (rn it's dependency is set to backend, but technically no dependencies)

The backend is connecting to the database via localhost, and is being served on the public ip
I can access it at just fine at mydomain.com:8000/api

但是，当我尝试访问mydomain.com时，docker设置为将端口3000转发到端口80，但是它无法请求React和，我在很多类似问题中获得了err_connection_refused错误

，人们忘记了向前端口3000到80，但是我要这样做...

当我安装npm＆amp＆amp＆amp;我的Ubuntu服务器上的React项目，

当我将端口从“ react_port_port：80”更改为“ 3000：3000”和“ 3000”和“ 3000”和这是可以通过我们的公共知识产权访问的。

我应该在主Linux服务器上将3000转发3000至80吗？该怎么办？

docker文件

前端docker文件

# pull official base image for node
FROM node:16-buster-slim

# set working directory
WORKDIR /app

# add `/app/node_modules/.bin` to PATH
ENV PATH /app/node_modules/.bin:$PATH

# install dependencies
COPY package.json ./
COPY package-lock.json ./
RUN npm i -g npm@latest
RUN npm install

# copy all src files to the container
COPY . .

# Expose port
EXPOSE 3000
EXPOSE 80

# start the web app
CMD ["npm", "run", "start"]

原文

Basically, I'm running a webapp with this stack:
Backend: FastAPI (python) which depends on database
Database: MySQL (being connected with via python-connector)
Frontend: React Functional (rn it's dependency is set to backend, but technically no dependencies)

The backend is connecting to the database via localhost, and is being served on the public ip
I can access it at just fine at mydomain.com:8000/api

However when I'm trying to access mydomain.com, docker is setup to forward port 3000 to port 80, however it can't request react and, I get the ERR_CONNECTION_REFUSED error

In alot of similar issues people forget to forward port 3000 to 80 however i'm doing this...

Also, when I install npm & the react project on my Ubuntu Server, the frontend is accessible via mydomain.com:3000

In the docker-compose.yml when I change the ports from "REACT_PORT : 80 " To "3000 : 3000 " And that's accessible via our public ip.

Should I just port forward 3000 to 80 on the main linux server? how to do?

我放弃了docker，现在使用nginx指向80至3000的端口...

基本上，在我的docker-compose.ym中，我将react端口指向自身：

  frontend:
    container_name: react-frontend
    build: ./frontend/client
    ports:
      - "${REACT_PORT}:${REACT_PORT}"
    depends_on:
      - backend
    networks:
      - backend
    restart: always

并且使用nginx，我编辑了配置文件执行：

​

等

server {
        listen 80;
        location / {proxy_pass http://localhost:3000/; }
        }

nano 然后重新加载Nginx，现在Docker在端口3000中转发，Nginx将80指向该端口。

这种方法有效，我仍然不明白为什么Docker无法将其转发，我什至检查了我的Netstat，端口80上什么都没运行...
诡异的...

I gave up with docker and now use NGINX to point port 80 to 3000...

Basically, in my docker-compose.yml I point the react port to itself like:

  frontend:
    container_name: react-frontend
    build: ./frontend/client
    ports:
      - "${REACT_PORT}:${REACT_PORT}"
    depends_on:
      - backend
    networks:
      - backend
    restart: always

And with NGINX, I edit the config file doing:
nano etc/nginx/nginx.conf

then in the http {} section of this config, I removed include /etc/nginx/sites-enabled/*;

and added

server {
        listen 80;
        location / {proxy_pass http://localhost:3000/; }
        }

and then reloaded nginx, now docker is forwarding at port 3000 and nginx is pointing 80 to that port.

This method works, I still don't understand why Docker wasn't able to port forward that, I even checked my netstat and nothing was running on port 80...
weird...
