# linuxserver/cops

COPS, by Sébastien Lucas, stands for Calibre OPDS (and HTML) Php Server.

COPS links to your Calibre library database and allows downloading and emailing of books directly from a web browser and provides a OPDS feed to connect to your devices.

Changes in your Calibre library are reflected immediately in your COPS pages.

See : [COPS's home](http://blog.slucas.fr/en/oss/calibre-opds-php-server) for more details.

Don't forget to check the [Wiki](https://github.com/seblucas/cops/wiki).

## Why? (taken from the author's site)

In my opinion Calibre is a marvelous tool but is too big and has too much
dependencies to be used for its content server.

That's the main reason why I coded this OPDS server. I needed a simple
tool to be installed on a small server (Seagate Dockstar in my case).

I initially thought of Calibre2OPDS but as it generate static file no
search was possible.

Later I added an simple HTML catalog that should be usable on my Kobo.

So COPS's main advantages are :
 * No need for many dependencies.
 * No need for a lot of CPU or RAM.
 * Not much code.
 * Search is available.
 * With Dropbox / owncloud it's very easy to have an up to date OPDS server.
 * It was fun to code.

If you want to use the OPDS feed don't forget to specify feed.php at the end of your URL.

# Docker Container

## Usage

```
docker create \
	--name=cops \
	-v <path to data>:/config \
	-v <path to data>:/books \
	-e PGID=<gid> -e PUID=<uid>  \
	-e TZ=<timezone> \
	-p 80:80 \
	linuxserver/cops
```

**Parameters**

* `-p 80` - the port(s)
* `-v /config` - COPS Application Data
* `-v /books` - Calibre metadata.db location
* `-e PGID` for for GroupID - see below for explanation
* `-e PUID` for for UserID - see below for explanation
* `-e TZ` for timezone information, eg Europe/London

It is based on alpine-linux with S6 overlay, for shell access whilst the container is running do `docker exec -it cops /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:

```
  $ id <dockeruser>
    uid=1001(dockeruser) gid=1001(dockergroup) groups=1001(dockergroup)
```

## Setting up the application 

Unlike other implementations of COPS in a docker container,  the linuxserver version gives you access to `config_local.php` in `/config` to customise your install to suit your needs, including details of your email account etc...

## Info

* To monitor the logs of the container in realtime `docker logs -f cops`.

## Version Log

+ **12.08.16:** Release
