基于K8S平台的区块链即服务(Blockchain as a Service)

主要结构

  • k8s-cluster
    k8s集群,基于flannel网络,安装dashboard插件,还有其余插件等 (一个简单的k8s集群)
  • baas-nfs-shared
    其会生成baas-artifacts,baas-fabric-data,baas-k8s-config目录,baas-artifacts为存放生成的证书文件,baas-fabric-data为fabric网络映射出来的数据,baas-k8s-config为生成的k8s yaml定义文件
  • baas-template
    fabric k8s的模板文件,用于生成baas-k8s-config下的文件
  • fabric-engine
    用于生成 baas-nfs-shared的文件即目录结构和执行fabric操作
  • k8s-engine
    config文件是k8s master的$HOME/.kube/config文件,用于k8s client链接k8s集群,将baas-k8s-config下的在k8s集群创建启动
  • apimanager
    统一api接口管理,调用入口
  • baas-frontend
    baas admin 前端

部署步骤(简单3台centos虚拟机包含一台nfs,两台k8s集群)

  • 以k8s-cluster搭建k8s集群
  • k8s-master 和 k8s-engine 部署同一台centos
    • k8s-engine 的参数 kubeconfig 指向 $HOME/.kube/config即可
  • nfs服务器和 fabric-engine 部署同一台centos
    • 创建baas根目录
      • 复制 baas-template到其下
      • 创建nfs共享目录 baas-nfs-shared
    • 配置环境变量(相应修改)
      BaasRootPath=baas根目录
      BaasNfsServer=ip
      BaasK8sEngine=http://ip:5991
      
    • nfs安装和配置
      • yum -y install nfs-utils rpcbind
      • id (查看当前用户的uid和gid)
      • vim /etc/exports (添加配置,相应修改)
        /baas根目录/baas-nfs-shared 192.168.1.0/24(rw,sync,insecure,anonuid=当前用户的uid,anongid=当前用户的gid)
        
      • exportfs -r (配置生效)
      • service rpcbind start && service nfs start (启动rpcbind、nfs服务)
    • 启动 fabric-engine
  • apimanager 随便部署到其中一台centos
    • 安装mysql
      docker run -p 3306:3306 --name apimysql \
                 -e MYSQL_ROOT_PASSWORD=123456 \
                 -d mysql:5.7 
      
    • 通过 mysql.sql 初始化 mysql,对应修改config.yaml
    • 添加环境变量
    • 运行 apimanager
  • baas-frontend 随便部署到其中一台centos
    • npm run build:prod 打包
    • 用nginx部署,把打包生成的dist文件夹复制并重命名/usr/share/nginx/baas
    • 配置nginx.conf反向代理
