[Nzbhydra2](https://github.com/theotherp/nzbhydra2) is a meta search application for NZB indexers, the "spiritual successor" to NZBmegasearcH, and an evolution of the original application [NZBHydra](https://github.com/theotherp/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.
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](https://github.com/docker/distribution/blob/master/docs/spec/manifest-v2-2.md#manifest-list) and our announcement [here](https://blog.linuxserver.io/2019/02/21/the-lsio-pipeline-project/).
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.
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.
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`.

We publish various [Docker Mods](https://github.com/linuxserver/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.
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](#application-setup) section above to see if it is recommended for the image.
Below are the instructions for updating containers:
* 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)
**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.
