On it's own it will not allow you to watch anything. This addon at it's core does the following: 1. It will search the internet and collect information about movies and tv show torrents, then store it in a database. 2. It will then allow you to click on the movie or tv show you desire in Stremio and play it with no further effort. ## Using The project is shipped as an all-in-one solution. The initial configuration is designed for hosting only on your local network. If you want it to be accessible from outside of your local network, please see [not yet available]() ### Download Docker and Docker Compose v2 Download and install [Docker Compose](https://docs.docker.com/compose/install/), bundled with [Docker Desktop](https://docs.docker.com/desktop/) or, if using Linux, you can install [Docker Engine](https://docs.docker.com/engine/install/) and the [Docker Compose Plugin.](https://docs.docker.com/compose/install/linux/) ### Environment Setup Before running the project, you need to set up the environment variables. Copy the `.env.example` file to `.env`: ```sh cd deployment/docker cp .env.example .env ``` Then set any of the values you wouldd like to customize. ### DebridMediaManager setup (optional) There are some optional steps you should take to maximise the number of movies/tv shows we can find. We can search DebridMediaManager hash lists which are hosted on GitHub. This allows us to add hundreds of thousands of movies and tv shows, but it requires a Personal Access Token to be generated. The software only needs read access and only for public respositories. To generate one, please follow these steps: 1. Navigate to GitHub settings -> Developer Settings -> Personal access tokens -> Fine-grained tokens (click [here](https://github.com/settings/tokens?type=beta) for a direct link) 2. Press `Generate new token` 3. Fill out the form (example data below): ``` Token name: KnightCrawler Expiration: 90 days Description: Respository access (checked) Public Repositories (read-only) ``` 4. Click `Generate token` 5. Take the new token and add it to the bottom of the [.env](.env) file ``` GithubSettings__PAT= ``` ### Run the project Open a terminal in the project directory and run the command: ```sh cd deployment/docker docker compose up -d ``` It will take a while to find and add the torrents to the database. During initial testing, in one hour it's estimated that around 200,000 torrents were located and added to the queue to be processed. For best results, you should leave everything running for a few hours. To add the addon to Stremio, open a web browser and navigate to: [http://127.0.0.1:7000](http://127.0.0.1:7000) ### Monitoring with Grafana and Prometheus (Optional) To enhance your monitoring capabilities, you can use Grafana and Prometheus in addition to RabbitMQ's built-in management interface. This allows you to visualize and analyze RabbitMQ metrics with more flexibility. With postgres-exporter service, you can also monitor Postgres metrics. #### Accessing RabbitMQ Management You can still monitor RabbitMQ by accessing its management interface at [http://127.0.0.1:15672/](http://127.0.0.1:15672/). Use the provided credentials to log in and explore RabbitMQ's monitoring features (the default username and password are `guest`). #### Using Grafana and Prometheus Here's how to set up and use Grafana and Prometheus for monitoring RabbitMQ: 1. **Start Grafana and Prometheus**: Run the following command to start both Grafana and Prometheus: ```sh cd deployment/docker docker compose -f docker-compose-metrics.yml up -d ``` - Grafana will be available at [http://127.0.0.1:3000](http://127.0.0.1:3000). - Prometheus will be available at [http://127.0.0.1:9090](http://127.0.0.1:9090). - The default admin user for Grafana is `admin`, and the password is `admin_password`. 2. **Import Grafana Dashboard**: Import the RabbitMQ monitoring dashboard into Grafana: - You can use the following dashboard from Grafana's official library: [RabbitMQ Overview Dashboard](https://grafana.com/grafana/dashboards/10991-rabbitmq-overview/). - You can alse use the following dashboard [PostgreSQL Database](https://grafana.com/grafana/dashboards/9628-postgresql-database/) to monitor Postgres metrics. The Prometheus data source is already configured in Grafana, you just have to select it when importing the dashboard. Now, you can use these dashboards to monitor RabbitMQ and Postgres metrics. > [!NOTE] > If you encounter issues with missing or unavailable data in Grafana, please ensure on [Prometheus's target page](http://127.0.0.1:9090/targets) that the RabbitMQ target is up and running. ## Importing external dumps A brief record of the steps required to import external data, in this case the rarbg dump which can be found on RD: ### Import data into database Using [pgloader](https://pgloader.readthedocs.io/en/latest/ref/sqlite.html) we can import other databases into Knight Crawler. For example, create a file called `db.load` containing the following: ``` load database from sqlite:///tmp/rarbg_db.sqlite into postgresql://postgres:postgres@localhost/knightcrawler with include drop, create tables, create indexes, reset sequences set work_mem to '16MB', maintenance_work_mem to '512 MB'; ``` Then run `pgloader db.load` to create a new `items` table. ### INSERT INTO ingested_torrents > [!NOTE] > This is specific to this example external database, other databases may/will have different column names and the sql command will require tweaking > [!IMPORTANT] > The `processed` field should be false so that the consumers will properly process it. Once the `items` table is available in the postgres database, put all the tv/movie items into the `ingested_torrents` table using `psql`. This can be done by attaching to the postgres docker container ``` docker exec -it knightcrawler-postgres-1 psql -d knightcrawler -c " INSERT INTO ingested_torrents (name, source, category, info_hash, size, seeders, leechers, imdb, processed) SELECT title, 'RARBG', cat, hash, size, NULL, NULL, imdb, false FROM items where cat='tv' OR cat='movies';" ``` ## Selfhostio to KnightCrawler Migration With the renaming of the project, you will have to change your database name in order to keep your existing data. **With your existing stack still running**, run: ``` docker exec -it torrentio-selfhostio-postgres-1 psql -c " SELECT pg_terminate_backend(pid) FROM pg_stat_activity WHERE pid <> pg_backend_pid() AND datname = 'selfhostio'; ALTER DATABASE selfhostio RENAME TO knightcrawler;" ``` Make sure your postgres container is named `torrentio-selfhostio-postgres-1`, otherwise, adjust accordingly. This command should return: `ALTER DATABASE`. This means your database is now renamed. You can now pull the new changes if you haven't already and run `docker compose up -d`. ## To-do - [ ] Add a section on external access - [ ] Add a troubleshooting section
