vite 打包docker，宿主和镜像无法联通

1. 在vite.config.js中按如下配置，以及导出端口

import { defineConfig } from 'vite'
import vue from '@vitejs/plugin-vue'
// https://vitejs.dev/config/
export default defineConfig({
  plugins: [vue()],
  server: {
    watch: {
      usePolling: true,
    },
    host: true, // needed for the Docker Container port mapping to work
    strictPort: true,
    port: 5173, // you can replace this port with any port
  }
})

2. Dockerfile 编写

   FROM node
   WORKDIR /app
   COPY package.json .
   RUN npm i
   COPY . .
   EXPOSE 5173
   CMD ["npm", "run", "dev"]
