最近在使用docker-compose搭建calibre-web

但是拉取的镜像文件在启动过程中都会提示db无效 ，看网上说是目录权限问题或者无法生成metadata.db

最后发现其实都不对

calibre-web只是一个web支持，它还是需要使用到已有calibre程序的数据库文件【 此应用程序要求您在 /books 位置拥有现有的 calibre 数据库 】

那么知道这个问题以后可以通过初始化metadata.db去解决该问题

使用docker exec -it calibre-web /bin/bash 进入容器目录

cd /config 目录下创建 metadata_generator.sh 文件,文件内容如下:

#!/bin/bash

FILE=/books/metadata.db
PUID=1000
PGID=1000

if test -f "$FILE"; then
    echo "$FILE already exists, skipping generation."
else
    echo "$FILE does not exists, generating..."
    cd /app/calibre/bin
    calibredb restore_database --really-do-it --with-library /books
    echo "$FILE created, setting permissions..."
    chmod a+w $FILE
    # this is needed for uploads, you can remove it if you don't want to allow uploads
    chown $PUID:$PGID /books
    echo "Permissions fixed, use /books as library path"
fi

chmod 755 metadata_generator.sh 赋予文件执行权限

sh metadata_generator.sh

[root@fb82c5f746df config]# sh metadata_generator.sh
/books/metadata.db does not exists, generating...
metadata_generator.sh: line 11: cd: /app/calibre/bin: No such file or directory
Starting restoring preferences and column metadata ... 0%
Cannot restore preferences. Backup file not found. ... 100%
Restoring database succeeded
old database saved as /books/metadata_pre_restore.db
/books/metadata.db created, setting permissions...
Permissions fixed, use /books as library path

之后在books文件夹中生成了我们需要的 metadata.db文件

没有再提示db无效

附上我的docker-compose.yml文件配置
