保存数据

Unraid 系统中，/boot、/mnt 之外的路径均在内存中，在下次重启后，会丢失。可以用如下方式来保存数据。

  • 第一步，数据保存在 /boot 路径下
  • 第二步，在 Unraid 系统启动时把文件拷贝到目标位置，有两种方式
    • 其一，更改 /boot/config/go 文件（shell 脚本），在 Unraid 系统启动时把文件拷贝到目标位置
    • 其二，使用 User Scripts 插件，在 Apps 中搜索安装，在 Plugins 中使用
      • 可以选择脚本运行时间，如果只需运行一次，选 At First Array Start Only 即可
      • 脚本路径在界面有显示，比如 /boot/config/plugins/user.scripts/scripts/dockerInit，这是一个目录，下面有个 script 文件用于编写命令

Docker

重启 Docker

1
$ /etc/rc.d/rc.docker restart

问题

环境变量无法清除

比如设置了 http_proxy，后面在界面移除环境变量，但是进入容器后，环境变量依然存在，需要手动修改容器配置。
