docker-compose 持久化的奇怪问题

[SlipStupig]

我使用 mongodb 服务，持久化到测试环境上，一切正常，我把相关持久化数据放到其它机器上，mongodb 居然不加载文件，每次都是初始化一次.

docker-compose:

   mongodb:
      restart: on-failure
      image:  mongo:3.4
      volumes:
        - /home/mongod:/data/db:rw

      ports:
        - "28017:27017"

      command: --maxConns 4096

      sysctls:
        net.core.somaxconn: 16240

怎么样才能让 mongodb 的数据库文件不用每次导入直接挂载呢？

检查文件权限和错误信息

@momocraft 目录给了 755，没有报错，只是数据没加载进去

[oyyd]

每次都持久化一次具体指的是？

[SlipStupig]

@oyyd 并没有读取到之前的数据，而是重新初始化新的集合出来

[HuangLibo]

之前用 docker 部署 gitlab 遇到过这个问题, 每次重启服务 gitlab 里面的数据就全没了, 最后就没用 docker, 直接在操作系统里安装了 gitlab

[SlipStupig]

@HuangLibo 你这种一般都是 volume 配置问题, 我的情况是加载了卷却没有数据
