Hydra is a meta search for NZB indexers and the "spiritual successor" to NZBmegasearcH. It provides easy access to a number of raw and newznab based indexers.

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 ghcr.io/linuxserver/hydra 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 from this image.

Compatible with docker-compose v2 schemas.

---
version: "2.1"
services:
hydra:
image: ghcr.io/linuxserver/hydra
container_name: hydra
environment:
- PUID=1000
- PGID=1000
- TZ=Europe/London
volumes:
- <path to data>:/config
- <nzb download>:/downloads
ports:
- 5075:5075
restart: unless-stopped

docker cli

docker run -d \
--name=hydra \
-e PUID=1000 \
-e PGID=1000 \
-e TZ=Europe/London \
-p 5075:5075 \
-v <path to data>:/config \
-v <nzb download>:/downloads \
--restart unless-stopped \
ghcr.io/linuxserver/hydra

Parameters

Docker 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.

Ports (-p)

Parameter

Function

5075

WebUI

Environment Variables (-e)

Env

Function

PUID=1000

for UserID - see below for explanation

PGID=1000

for GroupID - see below for explanation

TZ=Europe/London

Specify a timezone to use EG Europe/London.

Volume Mappings (-v)

Volume

Function

/config

Where hydra should store config files.

/downloads

NZB 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.

Umask for running applications

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.

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

THIS IMAGE HAS BEEN DEPRECATED.

Please use linuxserver/nzbhydra2 instead.

The web interface is at <your ip>:5075 , to set up indexers and connections to your nzb download applications.

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.

Support Info

  • Shell access whilst the container is running:

    • docker exec -it hydra /bin/bash

  • To monitor the logs of the container in realtime:

    • docker logs -f hydra

  • Container version number

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

  • Image version number

    • docker inspect -f '{{ index .Config.Labels "build_version" }}' ghcr.io/linuxserver/hydra
