我正在尝试使用docker-compose来运行两个容器-一个react示例应用程序和一个nginx作为反向代理。
我已经运行npx create-react-app react-app创建了第一个容器，并将以下Dockerfile添加到文件夹中-

FROM node
RUN yarn global add serve
WORKDIR /usr/src/app
COPY package.json yarn.lock ./
RUN yarn
COPY . ./
RUN yarn build
CMD serve -s build

然后，我在./nginx下创建了以下nginx配置文件-

server {
    listen       80;
    server_name  localhost;
    location / {
        root   /usr/share/nginx/html;
        index  index.html index.htm;
    }
    location /react {
        proxy_pass http://react:5000;
    }
}

最后，我在项目的根目录下创建了这个docker-compose.yaml文件-

version: '3'
services:
  nginx: 
    image: nginx:latest
    container_name: production_nginx
    volumes:
      - ./nginx/default.conf:/etc/nginx/conf.d/default.conf
    ports:
      - 80:80
      - 443:443

  react:
    build: ./react-app
    container_name: react-app
    expose:
      - "5000"
    ports:
      - 5000:5000

然后我使用docker-compose up --build来启动我的堆栈，但是当我使用http://localhost/react路径时，我在nginx访问日志中得到了以下错误-

在我看来，nginx似乎在nginx容器中寻找React静态资产，但我不确定它为什么不将这些请求代理到react容器中。

我还没有使用nginx反向代理到我的前端。只是连接从我的前端到我的服务器的请求。相反，你可以尝试直接通过nginx托管你的react-app。这里是我已经做到这一点的一种方法。
我没有运行两个容器，而是在react-app的根目录下设置了一个Dockerfile，Dockerfile对react应用进行了生产构建，然后将其复制到nginx中，托管在nginx配置中的/路径上，文件如下所示。

# Frontend build based on Node.js
FROM node:11.12.0-alpine as build-stage
RUN mkdir -p /usr/src/app
WORKDIR /usr/src/app
ENV PATH /usr/src/app/node_modules/.bin:$PATH
COPY package.json /usr/src/app/package.json
RUN npm install
RUN npm install react-scripts@latest -g
COPY . /usr/src/app
#RUN CI=true npm test
RUN npm run build

# Stage 1
# Production build based on Nginx with artifacts from Stage 0
FROM nginx:1.15.9-alpine
COPY config/nginx.conf /etc/nginx/conf.d/default.conf
COPY --from=build-stage /usr/src/app/build /usr/share/nginx/html
EXPOSE 80
CMD ["nginx", "-g", "daemon off;"]

在react-app的根目录下，我还有一个config目录，在这个目录下，我有一个nginx.conf文件，看起来像这样。

server {

    listen 80;
    server_name  localhost;

    location / {
        root   /usr/share/nginx/html;
        index  index.html index.htm;
        try_files $uri /index.html;                 
    }

    # redirect server error pages

    error_page   500 502 503 504  /50x.html;
    location = /50x.html {
        root   /usr/share/nginx/html;
    }

}

由于前端构建在第一步中被复制到nginx中，它现在可以在自己的文件系统中找到构建目录。之后，您可以在容器中构建和运行映像，一切都应该正确构建。我认为此时您所要做的就是将docker-compose.yml文件移动到react-app根目录中，摆脱react服务，将image: nginx:latest更改为build: .，然后运行docker-compose up -d。您也可以放弃compose，而只使用docker，运行docker build -t react-app，在构建之后，在react-app目录的根目录中运行docker run -d -p 80:80 react-app。这是一种非常简单的入门方法，可能并不完全符合您的要求。希望它能有所帮助。

找到this great blogpost后，我设法解决了这个问题，将nginx配置更改为-

upstream backend {
    server react:5000;
}

server {
    listen 80;
    server_name localhost;

    root /usr/src/app;

    location / {
        try_files $uri @backend;
    }

    location @backend {
        proxy_pass http://backend;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header Host $host;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        # Following is necessary for Websocket support
        proxy_http_version 1.1;
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection "upgrade";
    }
}
