Crawlab主从分布式部署

一、生产环境上我们不希望仅仅是简单部署，我们可以在多台服务器上分别部署Crawlab然后连接公共的MongoDB及Redis。这时候就需要让Mongo及Redis独立出来，避免耦合启动。
二、 Docker-Compose主节点
docker-compose.yml

version: '3.3'
services:
  master: 
    image: tikazyq/crawlab:latest
    container_name: master
    environment:

      # node register type 节点注册方式. 默认为 mac 地址，也可设置为 ip（防止 mac 地址冲突）
      CRAWLAB_SERVER_REGISTER_IP: "172.19.0.1"  # node register ip 节点注册IP. 节点唯一识别号，只有当 CRAWLAB_SERVER_REGISTER_TYPE 为 "ip" 时才生效
      # CRAWLAB_TASK_WORKERS: 8  # number of task executors 任务执行器个数（并行执行任务数）
      # CRAWLAB_RPC_WORKERS: 16  # number of RPC workers RPC 工作协程个数
      # CRAWLAB_SERVER_LANG_NODE: "Y"  # whether to pre-install Node.js 预安装 Node.js 语言环境
      # CRAWLAB_SERVER_LANG_JAVA: "Y"  # whether to pre-install Java 预安装 Java 语言环境
      # CRAWLAB_SETTING_ALLOWREGISTER: "N"  # whether to allow user registration 是否允许用户注册
      # CRAWLAB_SETTING_ENABLETUTORIAL: "N"  # whether to enable tutorial 是否启用教程
      # CRAWLAB_NOTIFICATION_MAIL_SERVER: smtp.exmaple.com  # STMP server address STMP 服务器地址
      # CRAWLAB_NOTIFICATION_MAIL_PORT: 465  # STMP server port STMP 服务器端口
      # CRAWLAB_NOTIFICATION_MAIL_SENDEREMAIL: [email protected]  # sender email 发送者邮箱
      # CRAWLAB_NOTIFICATION_MAIL_SENDERIDENTITY: [email protected]  # sender ID 发送者 ID
      # CRAWLAB_NOTIFICATION_MAIL_SMTP_USER: username  # SMTP username SMTP 用户名
      # CRAWLAB_NOTIFICATION_MAIL_SMTP_PASSWORD: password  # SMTP password SMTP 密码
    ports:    
      - "8080:8080" # frontend port mapping 前端端口映射
      - "8000:8000" # backend

Docker-Compose从节点

三、感慨
网上找了好久，官方文档写的也含含糊糊，让用户只能摸不着头脑，只能简简单单的部署，根本用不到生产环境。使用Kubernetes 多节点部署对服务器要求至少2核2G。作者条件不足也没有尝试成功。
