Podcast covers everything to do with getting the most from your Linux Server plus a focus on all things Docker and containerisation!

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 for more details.

Don't forget to check the 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.

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

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 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 to enable emailing of books, it also includes the dependencies required to directly view epub books in your browser.

Info

To monitor the logs of the container in realtime docker logs -f cops.
container version number

docker inspect -f '{{ index .Config.Labels "build_version" }}' cops

image version number

docker inspect -f '{{ index .Config.Labels "build_version" }}' linuxserver/cops
