linuxserver/nzbhydra2
Nzbhydra2 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/nzbhydra2:v2.10.2-ls49

Application Setup

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

Usage

To help you get started creating a container from this image you can either use docker-compose or the docker cli.
---
version: "2.1"
services:
nzbhydra2:
image: lscr.io/linuxserver/nzbhydra2:latest
container_name: nzbhydra2
environment:
- PUID=1000
- PGID=1000
- TZ=Europe/London
volumes:
- <path to data>:/config
- <nzb download>:/downloads
ports:
- 5076:5076
restart: unless-stopped
docker run -d \
--name=nzbhydra2 \
-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 \
lscr.io/linuxserver/nzbhydra2:latest

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 nzbhydra2 should store config files.
/downloads
NZB download folder.
Miscellaneous Options

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)

Docker Mods

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
