使用Docker Compose和Nginx代理React应用程序

reactjsdockernginxdocker-composereverse-proxy

我将使用docker-compose来运行两个容器——一个示例react应用程序和一个nginx反向代理。
我已经运行了npx create-react-app react-app来创建第一个容器，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

我随后创建了以下nginx配置文件，位于./nginx:
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，我在项目根目录创建了这个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

我随后使用docker-compose up --build来启动我的堆栈，但当我使用路径http://localhost/react时，在我的nginx访问日志中会得到以下错误-

似乎nginx在容器内查找React的静态资源，但我不确定为什么它没有将这些请求代理到react容器。你有什么解决方法吗？

我没有使用nginx反向代理到我的前端，只是将请求从我的前端连接到服务器。相反，您可以尝试直接通过nginx托管您的react-app。以下是我这样做的一种方式。
我在react-app的根目录下设置了一个Dockerfile，而不是运行两个容器。该Dockerfile对react应用程序进行生产构建，然后将其复制到nginx中，在nginx配置中托管位于/路径处。该文件如下所示。
# 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。在该目录中，有一个名为nginx.conf的文件，内容如下。

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;
    }

}

自从第一步中将前端构建文件复制到nginx中后，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镜像，一切都应该正确构建。我认为此时您所需做的一切就是将docker-compose.yml文件移动到react-app根目录中，去掉react服务，将image: nginx: latest更改为build: .，并运行docker-compose up -d。您还可以放弃使用compose，只需在react-app目录下运行docker build -t react-app，构建完成后再运行docker run -d -p 80:80 react-app即可。这是一个非常简单的入门方式，也许不完全符合您的期望，但希望能对您有所帮助。
感谢您详细的解释。问题是这是一个本地的尝试，试图复制生产示例，在该示例中Nginx将不得不从远程位置提供资源和应用程序。实际上，当我在等待答案时，我已经完成了它，现在我将发布解决方案。 - Yaron Idan
好的，我很想看看你是如何解决这个问题的。 - seanulus

在找到这篇优秀的博客文章之后，我通过更改nginx配置来解决了问题，具体配置如下 -

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";
    }
}

server_name localhost§ 行后面的符号是什么，Nginx 如何解释它？我在 Nginx 文档中找不到这方面的例子 - §。 - Nick
这是一个打字错误，感谢你发现了它。应该是一个 ;。现在已经修复了。 - Yaron Idan
