群晖部署-Calibreweb

最近家里搞了台群晖，准备部署个Calibreweb看看电子书，看了好多部署的教程老是不太成功，要么报错要么有问题的，很难搞。下面将部署流程分享一下，给大家参考，少走点弯路

镜像的选择

我们使用johngong/calibre-web,我们用这个镜像来构建应用，这个镜像已经添加了一些原始镜像没有的功能，可以更快的上手。我们直接拉取johngong/calibre-web镜像即可

配置

映射卷

我们需要映射镜像的卷

本地文件夹4:/usr/local/calibre-web/app/metadata_provider

这条配置下的本地文件夹4，需要放一个获取元数据的脚本，脚本内容如下，命名为NewDouban.py

环境变量

环境变量默认即可 大家可以根据需要进行调整

配置完成就可以正常启动了
