[Calibre-Web](https://github.com/janeczku/calibre-web) is a web app providing a clean interface for browsing, reading and downloading eBooks using an existing Calibre database. It is also possible to integrate google drive and edit metadata and your calibre library through the app itself.
This software is a fork of library and licensed under the GPL v3 License.
`The parameters are split into two halves, separated by a colon, the left hand side representing the host and the right the container side.
For example with a port -p external:internal - what this shows is the port mapping from internal to external of the container.
So -p 8080:80 would expose port 80 from inside the container to be accessible from the host's IP on port 8080
http://192.168.x.x:8080 would show you what's running INSIDE the container on port 80.`
*`-p 8083` - calibre-web gui port
*`-v /config` - where calibre-web stores it's database
*`-v /books` - where your calibre database is located
*`-e PGID` for GroupID - see below for explanation
*`-e PUID` for UserID - see below for explanation
It is based on alpine linux with s6 overlay, for shell access whilst the container is running do `docker exec -it calibre-web /bin/bash`.
### User / Group Identifiers
Sometimes when using data volumes (`-v` flags) permissions issues can arise between the host OS and the container. We avoid this issue by allowing you to specify the user `PUID` and group `PGID`. Ensure the data volume directory on the host is owned by the same user you specify and it will "just work" ™.
In this instance `PUID=1001` and `PGID=1001`. To find yours use `id user` as below:
