Readarr - Book Manager and Automation (Sonarr for Ebooks)
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 ghcr.io/linuxserver/readarr 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 |
This image provides various versions that are available via tags. latest tag usually provides the latest stable version. Others are considered under development and caution must be exercised when using them.
| Tag | Description |
|---|---|
| nightly | Nightly Readarr releases |
Access the webui at <your-ip>:8787, for more information check out Readarr.
We have set /books and /downloads as optional paths, this is because it is the easiest way to get started. While easy to use, it has some drawbacks. Mainly losing the ability to hardlink (TL;DR a way for a file to exist in multiple places on the same file system while only consuming one file worth of space), or atomic move (TL;DR instant file moves, rather than copy+delete) files while processing content.
Use the optional paths if you dont understand, or dont want hardlinks/atomic moves.
The folks over at servarr.com wrote a good write-up on how to get started with this.
Here are some example snippets to help you get started creating a container.
docker-compose (recommended, click here for more info)
---
version: "2.1"
services:
readarr:
image: ghcr.io/linuxserver/readarr
container_name: readarr
environment:
- PUID=1000
- PGID=1000
- TZ=Europe/London
volumes:
- /path/to/data:/config
- /path/to/books:/books #optional
- /path/to/downloadclient-downloads:/downloads #optional
ports:
- 8787:8787
restart: unless-stoppeddocker cli (click here for more info)
docker run -d \
--name=readarr \
-e PUID=1000 \
-e PGID=1000 \
-e TZ=Europe/London \
-p 8787:8787 \
-v /path/to/data:/config \
-v /path/to/books:/books `#optional` \
-v /path/to/downloadclient-downloads:/downloads `#optional` \
--restart unless-stopped \
ghcr.io/linuxserver/readarrContainer 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 8787 |
The port for the Readarr webinterface |
-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, this is required for Readarr |
-v /config |
Database and Readarr configs |
-v /books |
Location of Book library on disk (See note in Application setup) |
-v /downloads |
Location of download managers output directory (See note in Application setup) |
You can set any environment variable from a file by using a special prepend FILE__.
As an example:
-e FILE__PASSWORD=/run/secrets/mysecretpasswordWill set the environment variable PASSWORD based on the contents of the /run/secrets/mysecretpassword file.
For all of our images we provide the ability to override the default umask settings for services started within the containers using the optional -e UMASK=022 setting.
Keep in mind umask is not chmod it subtracts from permissions based on it's value it does not add. Please read up here before asking for support.
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)
We publish various Docker Mods to enable additional functionality within the containers. The list of Mods available for this image (if any) as well as universal mods that can be applied to any one of our images can be accessed via the dynamic badges above.
- Shell access whilst the container is running:
docker exec -it readarr /bin/bash - To monitor the logs of the container in realtime:
docker logs -f readarr - container version number
docker inspect -f '{{ index .Config.Labels "build_version" }}' readarr
- image version number
docker inspect -f '{{ index .Config.Labels "build_version" }}' ghcr.io/linuxserver/readarr
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:
- Update all images:
docker-compose pull- or update a single image:
docker-compose pull readarr
- or update a single image:
- Let compose update all containers as necessary:
docker-compose up -d- or update a single container:
docker-compose up -d readarr
- or update a single container:
- You can also remove the old dangling images:
docker image prune
- Update the image:
docker pull ghcr.io/linuxserver/readarr - Stop the running container:
docker stop readarr - Delete the container:
docker rm readarr - Recreate a new container with the same docker run parameters as instructed above (if mapped correctly to a host folder, your
/configfolder and settings will be preserved) - You can also remove the old dangling images:
docker image prune
-
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 readarr
-
You can also remove the old dangling images:
docker image prune
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.
- We recommend Diun for update notifications. Other tools that automatically update containers unattended are not recommended or supported.
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-readarr.git
cd docker-readarr
docker build \
--no-cache \
--pull \
-t ghcr.io/linuxserver/readarr: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 --resetOnce registered you can define the dockerfile to use with -f Dockerfile.aarch64.
- 28.07.21: - Initial Release.
