GitHub Stars GitHub Release GitHub Package Repository GitLab Container Registry Quay.io MicroBadger Layers Docker Pulls Docker Stars Build Status

THIS IMAGE IS DEPRECATED. We will continue releases with a new image under the correct name: linuxserver/nzbhydra2.

Hydra2 is a meta search application for NZB indexers, the "spiritual successor" to NZBmegasearcH, and an evolution of the original application NZBHydra.

It provides easy access to a number of raw and newznab based indexers. The application NZBHydra 2 is replacing NZBHydra 1 and supports migrating from V1. Be wary that there may be some compatibility issues for those migrating from V1 to V2, so ensure you back up your old configuration before moving over to the new version. NOTE: The last version that supports migration is linuxserver/hydra2:v2.10.2-ls49

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/hydra2 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:

ArchitectureTag
x86-64amd64-latest
arm64arm64v8-latest
armhfarm32v7-latest

Version Tags

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.

TagDescription
latestStable releases
devPrereleases from their GitHub

Usage

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

docker

docker create \
  --name=hydra2 \
  -e PUID=1000 \
  -e PGID=1000 \
  -e TZ=Europe/London \
  -p 5076:5076 \
  -v <path to data>:/config \
  -v <nzb download>:/downloads \
  --restart unless-stopped \
  linuxserver/hydra2

docker-compose

Compatible with docker-compose v2 schemas.

---
version: "2.1"
services:
  hydra2:
    image: linuxserver/hydra2
    container_name: hydra2
    environment:
      - PUID=1000
      - PGID=1000
      - TZ=Europe/London
    volumes:
      - <path to data>:/config
      - <nzb download>:/downloads
    ports:
      - 5076:5076
    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.

ParameterFunction
-p 5076WebUI
-e PUID=1000for UserID - see below for explanation
-e PGID=1000for GroupID - see below for explanation
-e TZ=Europe/LondonSpecify a timezone to use EG Europe/London.
-v /configWhere hydra2 should store config files.
-v /downloadsNZB download folder.

Environment variables from files (Docker secrets)

You can set any environment variable from a file by using a special prepend FILE__.

As an example:

-e FILE__PASSWORD=/run/secrets/mysecretpassword

Will set the environment variable PASSWORD based on the contents of the /run/secrets/mysecretpassword file.

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

The web interface is at <your ip>:5076 , to set up indexers and connections to your nzb download applications.

Docker Mods

Docker Mods

We publish various Docker Mods to enable additional functionality within the containers. The list of Mods available for this image (if any) can be accessed via the dynamic badge above.

Support Info

  • Shell access whilst the container is running: docker exec -it hydra2 /bin/bash
  • To monitor the logs of the container in realtime: docker logs -f hydra2
  • container version number
    • docker inspect -f '{{ index .Config.Labels "build_version" }}' hydra2
  • image version number
    • docker inspect -f '{{ index .Config.Labels "build_version" }}' linuxserver/hydra2

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/hydra2
  • Stop the running container: docker stop hydra2
  • Delete the container: docker rm hydra2
  • 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 hydra2
  • 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 hydra2
  • Let compose update all containers as necessary: docker-compose up -d
    • or update a single container: docker-compose up -d hydra2
  • 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 hydra2
    

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-hydra2.git
cd docker-hydra2
docker build \
  --no-cache \
  --pull \
  -t linuxserver/hydra2: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.
