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. [![hydra2](https://raw.githubusercontent.com/linuxserver/docker-templates/master/linuxserver.io/img/hydra-icon.png)](https://github.com/theotherp/nzbhydra2) ## 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](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/). 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. ### docker ``` docker create \ --name=hydra2 \ -e PUID=1000 \ -e PGID=1000 \ -e TZ=Europe/London \ -p 5076:5076 \ -v :/config \ -v :/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: - :/config - :/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 `:` 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. | Parameter | Function | | :----: | --- | | `-p 5076` | WebUI | | `-e PUID=1000` | for UserID - see below for explanation | | `-e PGID=1000` | for GroupID - see below for explanation | | `-e TZ=Europe/London` | Specify a timezone to use EG Europe/London. | | `-v /config` | Where hydra2 should store config files. | | `-v /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 `:5076` , to set up indexers and connections to your nzb download applications. ## 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](#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`. ## Versions * **23.03.19:** - Switching to new Base images, shift to arm32v7 tag. * **11.02.19:** - Add pipeline logic and multi arch. * **18.08.18:** - Bump java version to 10, (bionic currently refers to it as version 11). * **10.08.18:** - Rebase to ubuntu bionic. * **15.04.18:** - Change to port 5076 in the Dockerfile. * **11.01.18:** - Initial Release.
