podium micro-frontends 简单试用

以下是一个简单的podium 试用，包含了layout 以及podlets,使用docker 运行
podium 主要包含了两大部分

• podlets
  片段服务
• layouts
  片段组合服务

环境准备

• docker-compose 文件

 

version: '3'

services:

  layout:

     build:

       context: layouts/home

       dockerfile: Dockerfile

     ports:

     - "7000:7000"

  layout-index:

     build:

       context: podlets/indexpage

       dockerfile: Dockerfile

     ports:

     - "7100:7100"

  layout-userlogin:

     build:

       context: podlets/userlogin

       dockerfile: Dockerfile

     ports:

     - "7101:7101"

构建&&启动

• 构建镜像

docker-compose  build

• 启动

docker-compose up -d

• 效果

打开 http://localhodt:7000

 

说明

podlets 提供片段服务，layout 提供webpage 的组合服务，使用上还是比较简单的，同时里边也包含了版本的处理（通过元数据服务）
