linuxserver/ubooquity

Ubooquity is a free, lightweight and easy-to-use home server for your comics and ebooks. Use it to access your files from anywhere, with a tablet, an e-reader, a phone or a computer.

Supported Architectures

Our images support multiple architectures such as x86-64, arm64 and armhf. We utilise the docker manifest for multi-platform awareness. More information is available from docker here and our announcement here.

Simply pulling linuxserver/ubooquity should retrieve the correct image for your arch, but you can also pull specific arch images via tags.

The architectures supported by this image are:

Architecture	Tag
x86-64	amd64-latest
arm64	arm64v8-latest
armhf	arm32v7-latest

Usage

Here are some example snippets to help you get started creating a container.

docker

docker create \
  --name=ubooquity \
  -e PUID=1000 \
  -e PGID=1000 \
  -e TZ=Europe/London \
  -e MAXMEM=<maxmem> \
  -p 2202:2202 \
  -p 2203:2203 \
  -v <path to data>:/config \
  -v <path to books>:/books \
  -v <path to comics>:/comics \
  -v <path to raw files>:/files \
  --restart unless-stopped \
  linuxserver/ubooquity

docker-compose

Compatible with docker-compose v2 schemas.

---
version: "2"
services:
  ubooquity:
    image: linuxserver/ubooquity
    container_name: ubooquity
    environment:
      - PUID=1000
      - PGID=1000
      - TZ=Europe/London
      - MAXMEM=<maxmem>
    volumes:
      - <path to data>:/config
      - <path to books>:/books
      - <path to comics>:/comics
      - <path to raw files>:/files
    ports:
      - 2202:2202
      - 2203:2203
    restart: unless-stopped

Parameters

Container images are configured using parameters passed at runtime (such as those above). These parameters are separated by a colon and indicate <external>:<internal> respectively. For example, -p 8080:80 would expose port 80 from inside the container to be accessible from the host's IP on port 8080 outside the container.

Parameter	Function
-p 2202	The library port.
-p 2203	The admin port.
-e PUID=1000	for UserID - see below for explanation
-e PGID=1000	for GroupID - see below for explanation
-e TZ=Europe/London	Specify a timezone to use EG Europe/London.
-e MAXMEM=<maxmem>	To set the maximum memory. ( ex: set '1024' for 1GB )
-v /config	Config files and database for ubooquity.
-v /books	Location of books.
-v /comics	Location of comics.
-v /files	Location of raw files.

User / Group Identifiers

When using 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 any volume directories on the host are owned by the same user you specify and any permissions issues will vanish like magic.

In this instance PUID=1000 and PGID=1000, to find yours use id user as below:

  $ id username
    uid=1000(dockeruser) gid=1000(dockergroup) groups=1000(dockergroup)

 

Application Setup

IMPORTANT Ubooquity has now been upgraded to version 2 and for existing v1.x users we recommend cleaning your appdata and reinstalling, due to changes in the application itself making the two versions essentially incompatible with each other. Also the admin page and library pages are now on separate ports as detailed below.

Access the admin page at http://<your-ip>:2203/ubooquity/admin and set a password.

Then you can access the webui at http://<your-ip>:2202/ubooquity/

This container will automatically scan your files at startup.

MAXMEM

The quantity of memory allocated to Ubooquity depends on the hardware your are running it on. If this quantity is too small, you might sometime saturate it with when performing memory intensive operations. That’s when you get java.lang.OutOfMemoryError: Java heap space errors.

You can explicitly set the amount of memory Ubooquity is allowed to use (be careful to set a value lower than the actual physical memory of your hardware). Value is a number of megabytes ( put just a number, without MB )

If no value is set it will default to 512MB.

Support Info

• Shell access whilst the container is running: docker exec -it ubooquity /bin/bash
• To monitor the logs of the container in realtime: docker logs -f ubooquity
• container version number
  • docker inspect -f '{{ index .Config.Labels "build_version" }}' ubooquity
• image version number
  • docker inspect -f '{{ index .Config.Labels "build_version" }}' linuxserver/ubooquity

Updating Info

Most of our images are static, versioned, and require an image update and container recreation to update the app inside. With some exceptions (ie. nextcloud, plex), we do not recommend or support updating apps inside the container. Please consult the Application Setup section above to see if it is recommended for the image.

Below are the instructions for updating containers:

Via Docker Run/Create

• Update the image: docker pull linuxserver/ubooquity
• Stop the running container: docker stop ubooquity
• Delete the container: docker rm ubooquity
• Recreate a new container with the same docker create parameters as instructed above (if mapped correctly to a host folder, your /config folder and settings will be preserved)
• Start the new container: docker start ubooquity
• You can also remove the old dangling images: docker image prune

Via Docker Compose

• Update all images: docker-compose pull
  • or update a single image: docker-compose pull ubooquity
• Let compose update all containers as necessary: docker-compose up -d
  • or update a single container: docker-compose up -d ubooquity
• You can also remove the old dangling images: docker image prune

Via Watchtower auto-updater (especially useful if you don't remember the original parameters)

• Pull the latest image at its tag and replace it with the same env variables in one run:

  docker run --rm \
  -v /var/run/docker.sock:/var/run/docker.sock \
  containrrr/watchtower \
  --run-once ubooquity
  

Note: We do not endorse the use of Watchtower as a solution to automated updates of existing Docker containers. In fact we generally discourage automated updates. However, this is a useful tool for one-time manual updates of containers where you have forgotten the original parameters. In the long term, we highly recommend using Docker Compose.

• You can also remove the old dangling images: docker image prune

Building locally

If you want to make local modifications to these images for development purposes or just to customize the logic:

git clone https://github.com/linuxserver/docker-ubooquity.git
cd docker-ubooquity
docker build \
  --no-cache \
  --pull \
  -t linuxserver/ubooquity:latest .

The ARM variants can be built on x86_64 hardware using multiarch/qemu-user-static

docker run --rm --privileged multiarch/qemu-user-static:register --reset

Once registered you can define the dockerfile to use with -f Dockerfile.aarch64.
