PSA: Changes are happening

From August 2018 onwards, Linuxserver are in the midst of switching to a new CI platform which will enable us to build and release multiple architectures under a single repo. To this end, existing images for arm64 and armhf builds are being deprecated. They are replaced by a manifest file in each container which automatically pulls the correct image for your architecture. You'll also be able to pull based on a specific architecture tag.

TLDR: Multi-arch support is changing from multiple repos to one repo per container image.

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.

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	arm32v6-latest

Usage

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

docker

docker create \
  --name=ubooquity \
  -e PUID=1001 \
  -e PGID=1001 \
  -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=1001
      - PGID=1001
      - 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
    mem_limit: 4096m
    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=1001	for UserID - see below for explanation
-e PGID=1001	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.
-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=1001 and PGID=1001, to find yours use id user as below:

  $ id username
    uid=1001(dockeruser) gid=1001(dockergroup) groups=1001(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).

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 the image: docker-compose pull linuxserver/ubooquity
• Let compose update containers as necessary: docker-compose up -d
• You can also remove the old dangling images: docker image prune
