Hello I am making this post because I have only been able to find people with the opposite issue of the image working in docker but not with docker-compose.

你好，我做这个帖子是因为我只能找到在码头工作的形象相反问题的人，而不是码头-作曲。

I am working on a full-stack application utilizing React, Node, and Mongo.
Here is my set up

我正在开发一个利用React、Node和Mongo的全栈应用程序。这是我的设置

Running docker-compose up works and has the expected results. Everything connects and runs fine.

运行docker-compose up工作，并有预期的结果。一切都连接得很好，运行得也很好。

However I wanted to be able to run each image in isolation to perform testing.

但是，我希望能够单独运行每个映像来执行测试。

Building the React Dockerfile with docker build -t <name> followed by docker run <name> starts the image, dependecies get loaded but then the application hangs. It is unable to be canceled via terminal using ctrl+c, and can only be closed by deleting it from the docker desktop app (or maybe running in detached and killing somewhere else). Either way it does not work.

使用docker Build-t 和docker run 构建Reaction Dockerfile将启动映像，加载依赖项，但随后应用程序挂起。它不能通过终端使用ctrl+c取消，只能通过从docker桌面应用程序中删除它来关闭(或者可能在分离中运行并在其他地方杀死它)。无论哪种方式，它都行不通。

docker-compose.yml

Docker-compose.yml

version: "3.8"
services:
  react:
    build: ./re_react
    ports: 
      - 3000:3000
  node: #node service
    build: ./node #check for the node folder containing our docker file 
    ports:
      - 3001:3001
    environment: #env vars 
      MONGO_URL: mongodb://db-mongo:27017

Node: Dockerfile

节点：Dockerfile

FROM node:18
WORKDIR /server/src
COPY package*.json ./
RUN npm install

COPY . .
EXPOSE 3001
CMD ["node", "server.js"]

React: Dockerfile

反应：文档文件

FROM node:18-alpine
WORKDIR /react/

COPY package*.json ./
RUN npm install

COPY  public/ ./public
COPY src/ ./src

EXPOSE 3000
CMD ["npm", "start"]

I have tried moving some of the commands around in the React:Dockerfile to no avail, and I am considering it could be a port issue?

我试过在React：Dockerfile中移动一些命令，但没有用，我认为这可能是端口问题？

I'm totally unclear and lost on what the problem could be.

我完全不清楚问题是什么，也不知道是什么问题。

Also the node image runs fine (albiet it depends on an environment variable from the compose so it does generate an error after running, but it does not hang).

此外，节点映像运行良好(albiet它依赖于Compose中的环境变量，因此它在运行后确实会生成错误，但不会挂起)。

Output from docker build -t <name>

Docker内部版本的输出-t

The build seems to go without issue

这个版本似乎没有任何问题

Running with docker run <name
Program is dead in the water at this stage and nolonger recieving any inputs

使用Docker Run运行

I don't see the actual command, but you have to run the container along with publishing port to the host machine. Same is applicable for the Node.js project as well (backend).

我看不到实际的命令，但您必须运行容器以及将端口发布到主机。这同样适用于Node.js项目(后端)。

docker run --publish 3000:3000

However, this Dockerfile is NOT for production. For that, you have to build the app and serve it through a web server.

但是，此Dockerfile不用于生产。要做到这一点，你必须构建应用程序，并通过网络服务器提供服务。

FROM node:18-alpine AS build
WORKDIR /react
COPY package*.json ./
RUN npm install
COPY ./src .
RUN npm run build
FROM nginx:stable-alpine
COPY --from=build /react/build /usr/share/nginx/html

Try this both for frontend and backend

在前端和后端都尝试此功能

build:
context: #path of backend or frontend project
dockerfile: Dockerfile

BUILD：CONTEXT：#后台或前端项目dockerfile路径：dockerfile
