安装Apollo

准备在docker中部署一套Apollo配置中心的集群

参考官方文档

需要注意的点就是部署在docker中域名不要使用localhost，用host.docker.internal

1 表

在配置多环境时

• ApolloConfigDB分环境 每个环境建立一张表
• ApolloPortalDB不分环境 所有环境都共用一张表
• ServerConfig::apollo.portal.meta.servers要写入所有环境的meta地址
• ServerConfig::pollo.portal.env要写入所有环境的标识

sql文件

• ApolloConfigDB dev环境
• ApolloConfigDB fat环境
• ApolloPortalDB

2 启动容器

在/Users/dingrui/MyApp/docker-app/apollo目录下新建docker-compose.yml，执行docker-compose up -d

services:
  #Config Service提供配置的读取、推送等功能，服务对象是Apollo客户端
  apollo-configservice-dev:
    image: apolloconfig/apollo-configservice:2.3.0
    restart: on-failure:3
    container_name: apollo-configservice-dev
    volumes:

3 访问

在宿主机访问http://localhost:8070/进入后台页面

4 问题

用docker部署的情况下，根据meta url返回的是docker镜像中的home page地址

这样会导致集成Apollo客户端读取不到正确的配置信息

解决方案参考官方文档，启动客户端的时候-Dapollo.configService=http://127.0.0.1:8080/指定服务地址
