linuxserver/hydra2

GitHub Release MicroBadger Layers MicroBadger Size Docker Pulls Docker Stars Build Status

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 currently in its early stages and is in active development. 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.

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:

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.

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"
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

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

5076

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 hydra2 should store config files.

/downloads

NZB download folder.

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.
