携程 Apollo 配置中心 | 学习笔记 序章

欢迎关注个人公众号：  Coder编程

欢迎关注个人网站：www.52melrin.com

注：这篇文章主要在上一篇文章携程 Apollo 配置中心 | 学习笔记（十五）| 如何在Linux中部署Apollo配置中心集群(分布式)？的基础上，对Kubernetes的文件作出整理。

环境说明

       Kubernetes集群已搭建完毕：Master :192.168.220.83  其他的Slave:192.168.220.85,192.168.220.86,192.168.220.87

       Harbor镜像仓库已搭建完毕：192.168.220.84

       docker环境已搭建完毕：192.168.220.83

       docker-compose环境已搭建完毕：192.168.220.83

       其他的基础环境不做过多说明。

 

准备

       注：依然在上一篇文章的基础进行Kubernetes的环境部署，如果没有看上一篇文章的，请自动忽视本文！

     （1）部分修改说明：

      192.168.220.83  使用的端口分别是30070、30080、30090

      192.168.220.85  使用的端口分别是30071、30081、30091

      这个可以参考上一篇文章进行修改，并重新打包。

      这里为了在Kubernetes中保持高可用，我同时保证了不同的Ip与端口

      个人理解：Ip 对“外”暴露入口，端口对“内”暴露入口。这里的内外看个人理解了，这里我就不做过多详细解释说明。（要解释说明，估计又得扯一堆！）

    （2）目录：

       

       说明：因为Kubernetes 只能在Master主节点上进行发布，所以在83机子上新建两个目录。分别是apollo11,apollo22

        文中多处的两个文件。apollo.yaml 与docker-compose.yml 将在下面作出简要说明。

apollo-adminservice、apollo-configservice、apollo-portal 分别将打包好的 apollo-xxx-0.11.0-github.zip  与 apollo-xxx.jar

放入到对应的文件夹中。

运行

    （1）运行docker-compose

192.168.220.83，的机子

version: "3"  
  
services:  
  apollo-configservice:                                         ##容器服务名  
    container_name: apollo-configservice                        ##容器名  
    build: apollo-configservice/                                ##Dockerfile路径  
    image: 192.168.220.84/third_party/apollo-configservice:1.11.2                          ##镜像名  
    network_mode: host                                        ##网络设置  
    ports:  
      - "30080:30080"  
    volumes:  
      - "/Users/mobin/opt/logs/100003171:/opt/logs/100003171"    ##将/opt/logs/100003171目录挂载到宿主机的/Users/mobin/opt/logs/100003171方便在宿主机上查看日志  
    environment:  
      - spring_datasource_url=jdbc:mysql://xxxx:31101/ApolloConfigDB?characterEncoding=utf8  
      - spring_datasource_username=root  
      - spring_datasource_password=xxxx  
  
  apollo-adminservice:  
    container_name: apollo-adminservice  
    build: apollo-adminservice/  
    image: 192.168.220.84/third_party/apollo-adminservice:1.11.2
    network_mode: host  
    #net: "host"  
    ports:  
      - "30090:30090"  
    depends_on:  
      - apollo-configservice  
    volumes:  
      - "/Users/mobin/opt/logs/100003172:/opt/logs/100003172"  
    environment:  
      - spring_datasource_url=jdbc:mysql://xxxx:31101/ApolloConfigDB?characterEncoding=utf8  
      - spring_datasource_username=root  
      - spring_datasource_password=123456  
  
  apollo-portal:  
    container_name: apollo-portal  
    build: apollo-portal/  
    image: 192.168.220.84/third_party/apollo-portal:1.11.2
    network_mode: host  
    #net: "host"  
    ports:  
      - "30070:30070"  
    depends_on:  
      - apollo-adminservice
    #links:
     # - apollo-adminservice
     # - apollo-configservice  
    volumes:  
      - "/Users/mobin/opt/logs/100003173:/opt/logs/100003173"  
    environment:  
      - spring_datasource_url=jdbc:mysql://xxxx:31101/ApolloPortalDB?characterEncoding=utf8  
      - spring_datasource_username=root  
      - spring_datasource_password=123456
      - dev_meta=http://xxxx:30080

以上脱敏，个人根据自己信息进行修改！

运行：docker-compose up -d 

再次运行 docker-compose down 可以停掉docker-compose

     （2）查看镜像

     （3）上传至Harbor仓库

分别运行：

     docker push 192.168.220.84/third_party/apollo-portal:1.11.2

     docker push 192.168.220.84/third_party/apollo-adminservice:1.11.2

     docker push 192.168.220.84/third_party/apollo-configservice:1.11.2

     （4）运行apollo.yaml

运行命令：

      kubectl apply -f apollo.yaml

运行后可以看到已经成功的界面。

其他不做过多说明。

注：

      另外一台192.168.220.85 需求做相关修改，注意kubernetes中的标签labels、name 要作出修改。这里就不做赘述了。有其他问题可以留言!

到此，Kubernetes 集群部署 Apollo 分布式集群到此结束。
