Docker部署Cuckoo Sandbox：Web服务无法连接MongoDB的解决方法

按照Docker部署文档搭建Cuckoo Sandbox，执行docker-compose up -d后Mongo容器正常运行，可通过mongosh访问所有数据库，但Web服务无法启动，连接MongoDB时抛出如下错误：

CuckooCriticalError: Unable to connect to MongoDB: command SON([('listCollections', 1), ('cursor', {})]) on namespace cuckoo.$cmd failed: Unsupported OP_QUERY command: listCollections. The client driver may require an upgrade. In order to operate Cuckoo as per your configuration, a running MongoDB server is required.

使用的docker-compose.yml配置如下：

version: "2"

services:
  cuckoo:
    image: blacktop/cuckoo:2.0
    command: daemon
    ports:
      - "2042:2042"

• 修改MongoDB镜像版本为3.6.8，更新docker-compose.yml中mongo服务的配置：

  mongo:
    image: mongo:3.6.8
    ports:
      - 27017
    volumes:
      - mongo-data:/data/db
    networks:
      - cuckoo
  

• 执行系统参数配置命令，满足Elasticsearch的运行要求：

  sudo sysctl -w vm.max_map_count=262144
  

• 重新启动容器：

  docker-compose down && docker-compose up -d
