以上为之前写的携程Apollo配置中心相关文章，有需要，请自行查阅

接下来将介绍携程Apollo配置中心部署至Kubernetes集群中

注意：这里需要有一定的Kubernetes相关知识，和搭建好的环境。

一、环境准备

   这里就不过多介绍环境相关内容了，跟之前的类似。这里需要准备好Kubernetes的相关环境，如何搭建的，可以参考Kubernetes 1.9.0离线安装

一、修改配置文件

    接上一篇文章，修改部分文件

docker-compose.yml

version: "3"  
  
services:  
  apollo-configservice:                                         ##容器服务名  
    container_name: apollo-configservice                        ##容器名  
    build: apollo-configservice/                                ##Dockerfile路径  
    image: xx/third_party/apollo-configservice:0.10.8                           ##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:xx/ApolloConfigDB?characterEncoding=utf8  
      - spring_datasource_username=root  
      - spring_datasource_password=123456  
  
  apollo-adminservice:  
    container_name: apollo-adminservice  
    build: apollo-adminservice/  
    image: xxx/third_party/apollo-adminservice:0.10.8
    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:xx/ApolloConfigDB?characterEncoding=utf8  
      - spring_datasource_username=root  
      - spring_datasource_password=123456  
  
  apollo-portal:  
    container_name: apollo-portal  
    build: apollo-portal/  
    image: xxxx/third_party/apollo-portal:0.10.8
    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:xx/ApolloPortalDB?characterEncoding=utf8  
      - spring_datasource_username=root  
      - spring_datasource_password=123456
      - dev_meta=http://xxxx:30080

上述内容就不做过多介绍了。

之后使用Kompose将docker-compose文件转换成kubernetes相关文件。这里就不一一列举了。直接放文件！

以上为kubernetes启动文件。根据个人需要作出相应修改！

启动文件后，会发现客户端报一个错误：client端连接的是Kubernetes内网ip 10.x.x.x 导致apollo port端无法找到admin和config。

这时候需要修改apollo-adminservice 、apollo-configservice 中的 bootstrap.yml文件。

apollo-adminservice 中的bootstrap.yml文件修改同apollo-configservice

这里添加某一个kubernetes的外网ip地址，以及暴露的端口号。之后重新打包成镜像，上传至harbor 镜像库。重新运行上面的kubernetes.yaml文件。

即可看到成功部署，这里就不放图了。。。
