reactjs - 在 docker-compose 上使用 nginx 代理 React 应用程序

Question

我正在尝试使用 docker-compose 来运行 2 个容器 - 一个示例 react 应用程序和一个 nginx 作为反向代理。
我跑了npx create-react-app react-app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

然后我继续在 ./nginx 下创建以下 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，我创建了这个 docker-compose.yaml项目根目录中的文件 -

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启动我的堆栈，但是当我使用 http://localhost/react 时路径 我在 nginx 访问日志中收到以下错误 -

在我看来，nginx 正在 nginx 容器中寻找 Reacts 静态 Assets ，但我不确定它为什么不将这些请求代理到 react 容器。知道如何解决这个问题吗？

Answer 1

我没有使用 nginx 反向代理到我的前端。仅用于将来自我的前端的请求连接到我的服务器。相反，您可以尝试托管您的 react-app直接通过nginx。这是我这样做的一种方法。

我没有运行两个容器，而是设置了一个 Dockerfile在我的 react-app 的根目录中. Dockerfile对 react 应用程序进行生产构建，然后将其复制到 nginx 中以托管在 / nginx 配置中的路由。这就是那个文件的样子。

# 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的根我也有 config目录。在该目录中，我有 nginx.conf看起来像这样的文件。

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;
    }

}

由于在第一步中将前端构建复制到 nginx 中，因此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。我认为此时您所要做的就是移动您的 docker-compose.yml文件放入 react-app root，去掉 react服务，更改 image: nginx:latest至 build: .并运行 docker-compose up -d .您也可以放弃 compose并通过运行 docker build -t react-app 来使用 docker在构建之后，运行 docker run -d -p 80:80 react-app在 react-app 的根目录。这是一种非常简单的入门方法，可能不是您想要的。希望它有帮助。
