简单搭建qiankun的主应用和子应用并且用Docker进行服务器部署

在node18环境下，用react18创建qiankun主应用和两个子应用，react路由用V6版本，都在/main路由下访问子应用，用Dockerfile部署到腾讯云CentOS7.6服务器的8000端口进行访问，且在部署过程中进行nginx配置以进行合理的路由访问

要在 Node.js 18 环境下，用 React 18 创建一个基于 qiankun 的主应用和两个子应用，并使用 React Router v6 进行路由管理，所有子应用都在 /main 路由下访问，并使用 Docker 和 Nginx 部署到腾讯云 CentOS 7.6 服务器的 8000 端口，可以按照以下步骤进行：

1. 创建主应用和子应用

主应用

创建主应用：

npx create-react-app main-app --template typescript
cd main-app

安装 qiankun 和 react-router-dom：

npm install qiankun react-router-dom@6

配置主应用：
在 index.tsx 中配置 qiankun：

import React from 'react';
import ReactDOM from 'react-dom';
import { BrowserRouter as Router, Route, Routes } from 'react-router-dom';
import { registerMicroApps, start } from 'qiankun';
import App from './App';registerMicroApps([{name: 'sub-app-1',entry: '//localhost:7100',container: '#subapp-viewport',activeRule: '/main/sub-app-1',},{name: 'sub-app-2',entry: '//localhost:7200',container: '#subapp-viewport',activeRule: '/main/sub-app-2',},
]);start();ReactDOM.render(<React.StrictMode><Router><Routes><Route path="/*" element={<App />} /></Routes></Router></React.StrictMode>,document.getElementById('root')
);

修改 App.tsx：

import React from 'react';
import { Link } from 'react-router-dom';const App = () => (<div><nav><ul><li><Link to="/main/sub-app-1">Sub App 1</Link></li><li><Link to="/main/sub-app-2">Sub App 2</Link></li></ul></nav><div id="subapp-viewport"></div></div>
);export default App;

子应用 1

创建子应用 1：

npx create-react-app sub-app-1 --template typescript
cd sub-app-1

安装 qiankun 和 react-router-dom：

npm install qiankun react-router-dom@6

配置子应用 1：
在 index.tsx 中添加 qiankun 的生命周期函数：

import React from 'react';
import ReactDOM from 'react-dom';
import { BrowserRouter as Router, Route, Routes } from 'react-router-dom';
import App from './App';if (window.__POWERED_BY_QIANKUN__) {// eslint-disable-next-line @typescript-eslint/ban-ts-comment// @ts-ignore__webpack_public_path__ = window.__INJECTED_PUBLIC_PATH_BY_QIANKUN__;
}function render(props) {const { container } = props;ReactDOM.render(<React.StrictMode><Router basename={window.__POWERED_BY_QIANKUN__ ? '/main/sub-app-1' : '/'}><Routes><Route path="/*" element={<App />} /></Routes></Router></React.StrictMode>,container ? container.querySelector('#root') : document.getElementById('root'));
}if (!window.__POWERED_BY_QIANKUN__) {render({});
}export async function bootstrap() {console.log('sub-app-1 bootstraped');
}export async function mount(props) {console.log('sub-app-1 mounted');render(props);
}export async function unmount(props) {console.log('sub-app-1 unmounted');const { container } = props;ReactDOM.unmountComponentAtNode(container ? container.querySelector('#root') : document.getElementById('root'));
}

配置 package.json：

{"name": "sub-app-1","version": "0.1.0","private": true,"homepage": "/main/sub-app-1","dependencies": {"react": "^18.0.0","react-dom": "^18.0.0","react-scripts": "5.0.0","qiankun": "^2.4.0","react-router-dom": "^6.0.0"},"scripts": {"start": "PORT=7100 react-scripts start","build": "react-scripts build","test": "react-scripts test","eject": "react-scripts eject"}
}

子应用 2

子应用 2 的步骤和子应用 1 基本一致，项目名不一样和Router的 basename 不一样即可；端口为 7200，或者自行定义，和主应用和子应用1端口不一样即可

2. 创建 Dockerfile

为每个应用创建 Dockerfile，并使用 Nginx 作为静态文件服务器。

主应用 Dockerfile

在 main-app 目录下创建 Dockerfile：

# Build stage
FROM node:18 AS build# Set the working directory
WORKDIR /app# Copy the package.json and package-lock.json files
COPY package*.json ./# Install dependencies
RUN npm install# Copy the rest of the application code
COPY . .# Build the application
RUN npm run build# Production stage
FROM nginx:alpine# Copy the built files from the build stage
COPY --from=build /app/build /usr/share/nginx/html# Copy the Nginx configuration file
COPY nginx.conf /etc/nginx/nginx.conf# Expose port 80
EXPOSE 80# Start Nginx
CMD ["nginx", "-g", "daemon off;"]

子应用 1 Dockerfile

在 sub-app-1 目录下创建 Dockerfile：

# Build stage
FROM node:18 AS build# Set the working directory
WORKDIR /app# Copy the package.json and package-lock.json files
COPY package*.json ./# Install dependencies
RUN npm install# Copy the rest of the application code
COPY . .# Build the application
RUN npm run build# Production stage
FROM nginx:alpine# Copy the built files from the build stage
COPY --from=build /app/build /usr/share/nginx/html# Copy the Nginx configuration file
COPY nginx.conf /etc/nginx/nginx.conf# Expose port 80
EXPOSE 80# Start Nginx
CMD ["nginx", "-g", "daemon off;"]

子应用 2 Dockerfile

在 sub-app-2 目录下创建 Dockerfile：

# Build stage
FROM node:18 AS build# Set the working directory
WORKDIR /app# Copy the package.json and package-lock.json files
COPY package*.json ./# Install dependencies
RUN npm install# Copy the rest of the application code
COPY . .# Build the application
RUN npm run build# Production stage
FROM nginx:alpine# Copy the built files from the build stage
COPY --from=build /app/build /usr/share/nginx/html# Copy the Nginx configuration file
COPY nginx.conf /etc/nginx/nginx.conf# Expose port 80
EXPOSE 80# Start Nginx
CMD ["nginx", "-g", "daemon off;"]

3. 创建 Nginx 配置文件

为每个应用创建一个 Nginx 配置文件 nginx.conf。

主应用 Nginx 配置文件

在 main-app 目录下创建 nginx.conf：

server {listen 80;server_name localhost;location / {root /usr/share/nginx/html;index index.html index.htm;try_files $uri $uri/ /index.html;}location /main/sub-app-1/ {proxy_pass http://localhost:7100/;proxy_set_header Host $host;proxy_set_header X-Real-IP $remote_addr;proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;proxy_set_header X-Forwarded-Proto $scheme;}location /main/sub-app-2/ {proxy_pass http://localhost:7200/;proxy_set_header Host $host;proxy_set_header X-Real-IP $remote_addr;proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;proxy_set_header X-Forwarded-Proto $scheme;}
}

子应用 1 和子应用 2 Nginx 配置文件

在 sub-app-1 和 sub-app-2 目录下分别创建 nginx.conf：

server {listen 80;server_name localhost;location / {root /usr/share/nginx/html;index index.html index.htm;try_files $uri $uri/ /index.html;}
}

4. 构建和运行 Docker 容器

在每个应用的目录下，运行以下命令构建 Docker 镜像：

docker build -t main-app .
docker build -t sub-app-1 .
docker build -t sub-app-2 .

然后运行 Docker 容器：

docker run -d -p 8000:80 main-app
docker run -d -p 7100:80 sub-app-1
docker run -d -p 7200:80 sub-app-2

5. 部署到腾讯云 CentOS 7.6 服务器

连接到腾讯云服务器：
使用 SSH 连接到你的腾讯云 CentOS 7.6 服务器。

ssh your-username@your-server-ip

安装 Docker：
如果你的服务器上还没有安装 Docker，可以使用以下命令安装：

sudo yum update -y
sudo yum install -y docker
sudo systemctl start docker
sudo systemctl enable docker

将 Docker 镜像推送到 Docker Hub：
在本地机器上，将构建的 Docker 镜像推送到 Docker Hub：

docker tag main-app your-dockerhub-username/main-app
docker tag sub-app-1 your-dockerhub-username/sub-app-1
docker tag sub-app-2 your-dockerhub-username/sub-app-2docker push your-dockerhub-username/main-app
docker push your-dockerhub-username/sub-app-1
docker push your-dockerhub-username/sub-app-2

在服务器上拉取并运行 Docker 镜像：
在服务器上，拉取并运行 Docker 镜像：

docker pull your-dockerhub-username/main-app
docker pull your-dockerhub-username/sub-app-1
docker pull your-dockerhub-username/sub-app-2docker run -d -p 8000:80 your-dockerhub-username/main-app
docker run -d -p 7100:80 your-dockerhub-username/sub-app-1
docker run -d -p 7200:80 your-dockerhub-username/sub-app-2
