1、apollo

https://www.apolloconfig.com/#/zh/deployment/quick-start-docker

单机单环境
在这里插入图片描述
单机双环境

单机三环境

2、数据库准备

启动本地 mysql
初始化数据库

CREATE DATABASE ApolloConfigDB;
CREATE DATABASE ApolloPortalDB;

新增用户
userapollo/userapollo

CREATEUSER'userapollo'@'%' IDENTIFIED BY'userapollo';
GRANTALL PRIVILEGES ON ApolloConfigDB.*TO'userapollo'@'%';
GRANTALL PRIVILEGES ON ApolloPortalDB.*TO'userapollo'@'%';
FLUSH PRIVILEGES;

表结构&数据初始化
https://github.com/apolloconfig/apollo/tree/master/scripts/sql

3、启动后会用到的几个地址

http://127.0.0.1:8070/
Portal 登录地址，默认登录账户 apollo/admin
http://127.0.0.1:8080/
Eureka 管理页面
http://127.0.0.1:8080/services/config
service-config 配置查询接口
未来客户端通过下面 url 获取配置信息的拉取 url,即 homepageUrl 字段
客户端访问 http://127.0.0.1:8080/services/config

[{"appName":"APOLLO-CONFIGSERVICE","instanceId":"config-service:apollo-configservice:8080","homepageUrl":"http://config-service:8080"}]

http://127.0.0.1:8070/system_info.html
Portal 登录页面，查看 config-service、admin-service 运行状态
http://127.0.0.1:8070/server_config_manage.html#/portal_db
配置 apollo.portal.meta.servers
http://127.0.0.1:8070/server_config_manage.html#/config_db
配置 eureka.service.url

4、docker-compose运行 apollo

须知1：https://blog.youkuaiyun.com/bestcxx/article/details/140250249

须知 2：在启动顺序上，首次启动可能会失败，原因是 admin-service 、portal 需要等待 config-service 完全启动之后才能启动，这里建议首次启动后，重启 admin-service 和 portal
docker-compose 首次启动后，可以借助 Docker Desktop 管理Docker 容器,来进行重启操作

方式一：使用容器 hostName 作为网络媒介

修改数据库配置

UPDATE `ApolloConfigDB`.`ServerConfig` SET `Value` = 'http://config-service:8080/eureka/' WHERE (`Id` = '1');
UPDATE `ApolloPortalDB`.`ServerConfig` SET `Value` = '{\"dev\":\"http://config-service:8080\"}' WHERE (`Id` = '8');

apollo 客户端通过宿主机端口拉取配置(推荐)

JAVA_OPTS=-Deureka.instance.homePageUrl=http://127.0.0.1:8080
客户端通过 http://127.0.0.1:8080/services/config 获得

[{"appName":"APOLLO-CONFIGSERVICE","instanceId":"config-service:apollo-configservice:8080","homepageUrl":"http://127.0.0.1:8080"}]
此时 homepageUrl 为宿主机 IP:端口，通过端口映射方式完成请求转发

version: '3.6'

services:
  config-service:
    image: apolloconfig/apollo-configservice
    container_name: apollo-config-service
    hostname: config-service
    environment:
      - SPRING_DATASOURCE_URL=jdbc:mysql://host.docker.internal:3306/ApolloConfigDB?useSSL=false&characterEncoding=utf8
      - SPRING_DATASOURCE_USERNAME=userapollo
      - SPRING_DATASOURCE_PASSWORD=userapollo
      - JAVA_OPTS=-Deureka.instance.homePageUrl=http://127.0.0.1:8080
    ports:
      - 8080:8080 # 宿主机端口 : 容器端口

    hostname: admin-service

      - SPRING_DATASOURCE_USERNAME=userapollo
      - SPRING_DATASOURCE_PASSWORD=userapollo
      - CONFIGSERVICE_URL=http://config-service:8080
      - JAVA_OPTS=-Deureka.instance.homePageUrl=http://admin-service:8090
    ports:
      - 8090:8090
    depends_on:
      - config-service
    networks:
      apollo-network:

  portal:
    image: apolloconfig/apollo-portal
    container_name: apollo-portal
    hostname: portal
    environment:
      - SPRING_DATASOURCE_URL=jdbc:mysql://host.docker.internal:3306/ApolloPortalDB?useSSL=false&characterEncoding=utf8
      - SPRING_DATASOURCE_USERNAME=userapollo
      - SPRING_DATASOURCE_PASSWORD=userapollo
      - APOLLO_PORTAL_ENVS=dev
      - DEV_META=http://config-service:8080
      - JAVA_OPTS=-Deureka.instance.homePageUrl=http://portal:8070
    ports:
      - 8070:8070
    depends_on:
      - config-service
      - admin-service
    networks:
      apollo-network:

networks:

    #driver: bridge

apollo 客户端通过自定义hostName 拉取配置

修改宿主机 /etc/hosts 文件

127.0.0.1 config-service

docker-compose.yml

JAVA_OPTS=-Deureka.instance.homePageUrl=http://config-service:8080
客户端通过 http://127.0.0.1:8080/services/config 获得

[{"appName":"APOLLO-CONFIGSERVICE","instanceId":"config-service:apollo-configservice:8080","homepageUrl":"config-service:8080"}]
此时 homepageUrl 为自定义 hostName:端口，宿主机将根据 /etc/hosts 配置将请求映射本机 127.0.0.1，然后通过端口映射方式完成转发，这种方式需要本地配置私有化域名

services:
  config-service:
    image: apolloconfig/apollo-configservice
    container_name: apollo-config-service
    hostname: config-service
    environment:

      - JAVA_OPTS=-Deureka.instance.homePageUrl=http://config-service:8080

方式二：使用端口映射+固定 ip 作为网络媒介

修改数据库配置

UPDATE `ApolloConfigDB`.`ServerConfig` SET `Value` = 'http://192.168.128.2:8080/eureka/' WHERE (`Id` = '1');
UPDATE `ApolloPortalDB`.`ServerConfig` SET `Value` = '{\"dev\":\"http://192.168.128.2:8080\"}' WHERE (`Id` = '8');

docker-compose.yml

JAVA_OPTS=-Deureka.instance.homePageUrl=http://config-service:8080
客户端通过 http://127.0.0.1:8080/services/config 获得

[{"appName":"APOLLO-CONFIGSERVICE","instanceId":"config-service:apollo-configservice:8080","homepageUrl":"config-service:8080"}]
此时 homepageUrl 为容器内部 hostName:端口，宿主机将根据 /etc/hosts 配置将请求映射本机 127.0.0.1，然后通过端口映射方式完成转发

version: '3.6'

services:
  config-service:
    image: apolloconfig/apollo-configservice
    container_name: apollo-config-service
    hostname: config-service
    environment:
      - SPRING_DATASOURCE_URL=jdbc:mysql://host.docker.internal:3306/ApolloConfigDB?useSSL=false&characterEncoding=utf8
      - SPRING_DATASOURCE_USERNAME=userapollo
      - SPRING_DATASOURCE_PASSWORD=userapollo
      - JAVA_OPTS=-Deureka.instance.homePageUrl=http://127.0.0.1:8080
    ports:
      - 8080:8080 # 宿主机端口 : 容器端口
    networks:
      apollo-network:
        ipv4_address: 192.168.128.2

  admin-service:
    image: apolloconfig/apollo-adminservice
    container_name: apollo-admin-service
    hostname: admin-service
    environment:
      - SPRING_DATASOURCE_URL=jdbc:mysql://host.docker.internal:3306/ApolloConfigDB?useSSL=false&characterEncoding=utf8
      - SPRING_DATASOURCE_USERNAME=userapollo
      - SPRING_DATASOURCE_PASSWORD=userapollo
      - CONFIGSERVICE_URL=http://192.168.128.2:8080
    ports:
      - 8090:8090
    depends_on:
      - config-service
    networks:
      apollo-network:
        ipv4_address: 192.168.128.3

  portal:
    image: apolloconfig/apollo-portal
    container_name: apollo-portal
    hostname: portal
    environment:
      - SPRING_DATASOURCE_URL=jdbc:mysql://host.docker.internal:3306/ApolloPortalDB?useSSL=false&characterEncoding=utf8
      - SPRING_DATASOURCE_USERNAME=userapollo
      - SPRING_DATASOURCE_PASSWORD=userapollo
      - APOLLO_PORTAL_ENVS=dev
      - DEV_META=http://192.168.128.2:8080
    ports:
      - 8070:8070
    depends_on:
      - config-service
      - admin-service
    networks:
      apollo-network:
        ipv4_address: 192.168.128.4

networks:
  apollo-network:
    driver: bridge
    ipam:
      config:
        - subnet: 192.168.128.0/24

5、使用容器同时部署 apollo 和 mysql

Docker compose 本地部署 mysql 和其它容器

6、客户端
