Build a 100TB media server for $3/mo. The complete guide to Plex or Jellyfin, Real-Debrid, and DUMB with zero-buffering 4K streaming. - Author: Core Lab Joe - Tags: Real Debrid, Plex Media Server, Jellyfin, Docker, Media Server, #2025, #table-of-content Imagine a **100TB Plex/Jellyfin server** that fits in your pocket, costs **$3/month**, and never runs out of space! This guide shows you exactly how to connect Plex or Jellyfin to Real-Debrid using [Decypharr](https://corelab.tech/decypharr-setup-guide/), with or without DUMB, and [Docker](https://corelab.tech/arr-stack-docker-compose-guide/) so you can **stream cached media instantly** without storing files locally. If your Plex/Jellyfin Debrid setup has empty folders, buffering, or rclone/Zurg mount problems, this guide includes the exact working configuration and fixes! If you are tired of buying hard drives, managing RAID arrays, and worrying about drive failure, this guide is your exit strategy. By combining **Real-Debrid** with **Docker**, we can build an "Infinite" media server that streams 4K Remux content instantly without downloading a single file locally. While this guide focuses on Plex/Jellyfin, if you want the absolute easiest and zero-maintenance setup, you should read my [**Stremio +** **Real Debrid guide**](https://corelab.tech/stremio-setup-guide/) instead. ๐Ÿ“ก ****Update June 2026**: Recent Real Debrid filtering changes have caused 'infringing file' errors for some users. If you are experiencing empty folders or failed grabs, read my [dedicated guide on how to fix Real-Debrid Infringing File errors](https://corelab.tech/real-debrid-infringing-file-fix/) using updated Decypharr configurations. This is part of my Real-Debrid Media Server Series: Learning Path โ€ข Cloud-Hybrid & Debrid Streaming ### Mastering Infinite Media & Debrid Architecture Replace expensive NAS drive arrays with instant cloud caching, deploy Decypharr virtual symlinks, configure automated Usenet fallbacks, and eliminate playback errors.

Check out my [CachyOS Linux Gaming Guide](https://corelab.tech/cachyos-linux-gaming-guide-hydra-launcher/) to see how to plug your API key into Hydra Launcher to download your PC game archives at unrestricted speeds. ### **NOT for you if:** - If you only stream on one device, use [Stremio + Real-Debrid instead](https://corelab.tech/stremio-setup-guide/) - If you do not want to manage Docker, this may be too advanced - If you already have 100TB of local storage, you may not *need* this - But you might be looking for a way out of buying new hard drives! This is a natural evolution from a previous post: [Rapid Stremio & Real Debrid Guide (2025)Navigating the world of media consumption can be a complex choice between convenience, control and privacy. The decision often boils down to two distinct philosophies: a cloud-based, โ€œon-demandโ€ approach like Stremio with Real Debrid, or a self-hosted, โ€œcuratedโ€ library with Plex or Jellyfin. Regardless of if youโ€™re a seasoned media![](https://corelab.tech/content/images/icon/Glowing_CPU-2.png)Core LabCore Lab Joe![](https://corelab.tech/content/images/thumbnail/ksnip_20250917-132748.png)](https://corelab.tech/stremio-setup-guide/) In that solution, you can only utilize your incredible new streaming solution from **1 IP address / home / location at a time.** This ***unlocks*** the power to stream through a media server, to wherever and however many devices you so chose. You can stream to your phone while away from home, because Plex/Jellyfin act as the 'device' with the 1 IP connecting to Real-Debrid. The connection to Real-Debrid always comes from your home IP address! > This post will walk you through a **detailed** step by step technical guide, through the entire process to implement this **ultimate** self-hosted streaming service! --- ## ๐Ÿ—๏ธ Architecture: How "Dark IT Magic" Works Before we paste code, you need to understand the flow. We are using a stack called **DUMB** (Debrid Unlimited Media Bridge). It tricks Plex/Jellyfin into thinking the Cloud is a local Hard Drive. This is the secret Dark IT magic ๐Ÿ˜‰ **The Stack:** 1. **Real-Debrid:** The Storage (Cached Torrents). 2. ~~**Zurg:** The Driver (Mounts Real-Debrid as a filesystem).~~ 3. **Decypharr/Jellyseerr/Radarr/Sonarr:** The Brains (Finds content and adds it to the virtual drive). 1. Decypharr has rclone and webdav builtin, replacing Zurg's function into a more elegant & performant solution. 4. **Plex/Jellyfin:** The Player (Streams it to your TV). 5. **Reverse Proxy (SWAG/NGINX)**: Securely share your Jellyfin/services as needed.

DUMB is an all-in-one Docker container that includes ****Plex Media Server** pre-configured, along with the essential backend tools like ****Zurg** (for creating a virtual filesystem from Real Debrid) and ****Riven** (for content automation). It makes your Real Debrid cloud library appear as local files, which Plex/Jellyfin can then scan and serveโ€”all from one tidy container! We are going to deploy the entire stack using Docker Compose, integrating the DUMB container with the powerful \*arr automation suite, paying extra attention to the details that make or break a complex self-hosted setup.

You need 3.5 things before we launch: ### 1\. The Hardware You don't need a monster server. Because we are streaming, not transcoding storage, a modern Mini PC is perfect. - **Recommendation:** [**Intel N150 Mini PC**](https://linktwin.co/ppefhm?ref=corelab.tech) (Great QuickSync support for transcoding). - **OS:** Debian 13 Trixie (Recommended) or Ubuntu 24.04. - Instructions below will work on any debian based distro, and most likely anything that can run docker! - Storage all sorted out ([NAS / HDD](https://corelab.tech/homelab-hardware-guide/)s?) - I myself use my [custom server/nas](https://corelab.tech/diy-nas-server-build/). ### 2\. The Accounts - **Real-Debrid:** **Sign Up & Subscribe:** Go to the [Real Debrid](http://real-debrid.com/?id=12061754&ref=corelab.tech) website and ensure you have an active subscription. - **Get Your API Key:** Log in, navigate to **My Devices**, and find the section for your **API Key**. Copy this long string somewhere, notepad, etc... If you don't mind, sign up using my referrals below which helps this site!

Copy the alphanumeric string. - **Do this right before deploying DUMB, as it expires fast!** - **You also navigate to https://IPofYourPLEX:32400/web and "claim" the server this way.** ![Screenshot of RealDebrid website "My Devices" where you can access your API Private Token](https://corelab.tech/content/images/2026/05/Real-Debrid--22My-Devices-22-Private-API-key-1.webp) RealDebrid website "My Devices" where you can access your API Private Token. ### 3\. Your User IDs (PUID/PGID) & Folder Ownership ๐Ÿ’ฅ ****Don't skip**, read all of #3 so you know which root folders to point apps at later in the setup! To ensure your deployment is rock-solid, you need a dedicated environment where permissions won't get messy. Running everything as `root` is a recipe for disaster, and using your main personal account can get confusing but can work (/home/username/appdata/dumb/) Here is how to prep your permissions & pathways from scratch. ```bash # 1. Create the user sudo adduser mediauser sudo usermod -aG docker mediauser # 2. Get your PUID/PGID (Write these numbers down!) id mediauser # 3. Create the directory skeleton sudo mkdir -p /opt/appdata/dumb/{config,log,data,mnt/debrid} # 4. Set Ownership (CRITICAL) sudo chown -R mediauser:mediauser /opt/appdata/dumb sudo chmod -R 755 /opt/appdata/dumb ``` **What did we just create?** - **/config:** Where Plex and the \*Arrs store their settings. - **/log:** Where the system writes "what happened" if things break. - **/data:** For any small local metadata. - **/mnt/debrid:** **The Magic Folder.** This must stay empty so ~~Zurg~~ Decypharr can mount your cloud drive here. You'll see later (once you start the container up) that it creates additional folders inside the path you made for DUMB. These will be: ```BASH # Where decypharr mounts your cloud files to: /mnt/debrid/decypharr/realdebrid/__all__/ # Sonarr & Radarr folders, made by those apps: /mnt/debrid/decypharr_symlinks/sonarr-debrid /mnt/debrid/decypharr_symlinks/radarr-debrid ``` **Note:** You might not see those last two folders be created by sonarr & radarr until you try to 'add' something. Kinda like a chicken before the egg. This is why (as you'll see later in the guide) I ended up creating a /tv and /movies folder; unnecessarily. ### The FUSE Folder Check Zurg requires **FUSE** to mount the virtual drive. If this check fails, **the guide won't work.** ```bash ls -l /dev/fuse ``` - **Success looks like:** `crw-rw-rw- 1 root fuse ... /dev/fuse` - **Failure looks like:** `ls: cannot access '/dev/fuse': No such file or directory` - **If it exists:** Move to the next step. - **If missing:** Run `sudo apt update && sudo apt install libfuse2 -y`. - **Make it permanent (The Pro Move)** To ensure FUSE starts every time your server reboots, run this one-liner: ```bash echo "fuse" | sudo tee -a /etc/modules ``` --- ![Stop: Disable These Plex Settings or Real-Debrid May Ban Your Account](https://corelab.tech/content/images/2026/05/RealDebrid-Banhammer.webp) Stop: Disable These Plex Settings or Real-Debrid May Ban Your Account. ๐Ÿ’ฅ โš ๏ธ CRITICAL WARNING: YOU WILL BE BANNED BY REAL DEBRID IF YOU SKIP THIS ****Stop. Read this twice.** Real-Debrid is ****not** a local hard drive. It is a "caching" service that works like a streaming service. โš ๏ธ ****Real-Debrid will ban you permanently** if you leave Plex's default scanning settings on. Because the drive is in the cloud, Plex/Jellyfin trying to "generate thumbnails" looks like a massive DDoS attack to Real-Debrid. If you leave Plex's default "Scanner" settings enabled, Plex will attempt to download *every single frame* of your movies to generate thumbnails, detect intros, and analyze audio levels. - **The Result:** Real-Debrid will see thousands of rapid API requests (simulating massive abuse), and they will **ban your account permanently** without a refund. **You MUST disable the following settings in Plex or Jellyfin (Settings -> Library):** - โŒ **Generate video preview thumbnails:** set to **NEVER** - โŒ **Generate intro video markers:** set to **NEVER** - โŒ **Generate chapter thumbnails:** set to **NEVER** - โŒ **Analyze audio tracks for loudness:** set to **NEVER** - โŒ **Perform extensive media analysis:** UNCHECK this box (if available in Scheduled Tasks) **Why?** These features require reading the *entire* file.

The user permission check on render or video can be a bit aggressive, so if everything else checks out as ok, you're prob GTG just fire it up and see. What's nice is it outputs what it detects in /dev/dri/ for you ;) --- ## Navigating the Real-Debrid Purge: How to Filter Blocked Keywords in Radarr and Sonarr If you have been running a self-hosted media stack backed by Real-Debrid over the last few days, your download queues likely ran into a brick wall. In a sudden shift to comply with enforcement mandates, Real-Debrid rolled out an automated keyword filtration system. The platform now systematically blocks specific tracking markers, release group strings, and structural scene tags, throwing instant "infringing file" errors back to your automation pipeline. When services like Decypharr attempt to resolve these automated grabs, the pipeline locks up trying to process files that are permanently blacklisted on the backend. Rather than micro-managing your queues or waiting for an upstream fix, the cleanest mitigation is to inject these blocked terms straight into your Arrs as negative criteria. By doing this, your applications filter out problematic releases before they ever hit your download client. ### The Backend Target: Understanding the Purge Pattern The automated compliance script running on Debrid infrastructure isnโ€™t parsing content semantics; it is querying exact string patterns in the release payload titles. Extensive logs and community testing indicate the filtering mechanisms aggressively flag traditional scene metadata tags, major tracking nodes, and streaming platform fingerprints. To drop these toxic assets cleanly before they parse into your ecosystem, we can condense the known targeted tags into a case-insensitive regular expression: ```BASH (rartv|rarbg|eztv)\]|\b(YTS|Erai-raws|WEBRip|WEB-DL|AMZN|DSNP|CR)\b ``` > โš ๏ธ **Engineering Note on Content Availability:** Because markers like `WEB-DL` and platforms like `AMZN` or `DSNP` constitute a massive percentage of current automated indexer results, filtering them will sharply lower your automated catch rate. This filter is designed as a protective operational shield for your debrid queues, not a silver bullet for content discovery. ### Implementing Custom Formats in Radarr Radarr handles release evaluation elegantly through Custom Formats linked directly to your Quality Profiles. This configuration penalizes matching indexer flags to ensure they are ignored during routine RSS feeds and interactive parsing cycles. ### Step 1: Initialize the New Custom Format Navigate to **Settings > Custom Formats**. Click the **\+ Add New** button. Set the format name to `RD Infringing Block` or a similar internal identifier. ### Step 2: Configure the RegEx Specification Add a condition under the Specifications block. Set the type to **Release Title**. Paste the regex token with the case-insensitive inline flag prepended: ```BASH (rartv|rarbg|eztv)\]|\b(YTS|Erai-raws|WEBRip|WEB-DL|AMZN|DSNP|CR)\b ``` Save the custom configuration block. ### Step 3: Bind and Penalize in the Active Profile Go to **Settings > Profiles** and open your primary Quality Profile. Scroll down to the Custom Formats scoring section. Locate your new filter profile, toggle the checkmark to active, and assign it a heavily punitive score value such as **`-10000`**. Save your profile changes. ### Implementing Custom Formats in Sonarr (v4 & Legacy v3) The solution path for Sonarr depends completely on the version tier your homelab environment is currently tracking. ### Sonarr v4 Infrastructure If you are running modern v4 deployments, the operational step-list is identical to Radarr. Add the regex configuration under **Settings > Custom Formats**, assign it to your active **Quality Profiles**, and drop its weight modifier down to **`-10000`**. ### Long-Term Automation Resilience Adding these filters keeps your download client queues clear of dead links, but it highlights the risks of relying on a single cloud dependency for data access. If your automation rate drops too low due to these keywords being blocked, consider setting up a fallback infrastructure. Integrating Usenet indexers or private trackers alongside your Debrid setup will keep your home automation stable, no matter what compliance updates happen on the backend. More to follow on integration of other options later... --- ## **โšก Phase 2A: DUMB Docker Compose Generator** Don't want to edit YAML files manually? Use my **Config Generator**. It automatically applies the "Golden Config" flags based on your inputs. ### ๐Ÿ“‹ Essential Pre-Deployment Variables Gather these values from your host system first. If these are wrong, the stack will either fail to start or have no internet access. | Variable | Description | How to find it / Example | | ---------------------- | --------------------------------------- | --------------------------------------------------------------------- | | **PUID** | Your Linux User ID | Run: id -u (e.g., 1000) | | **PGID** | Your Linux Group ID | Run: id -g (e.g., 1000) | | **TZ** | Your System Timezone | e.g., America/Toronto | | **RD\_API\_KEY** | Your Real Debrid API Key | Found in your RD API settings | | **HOST\_CONFIG\_PATH** | Absolute path for config storage | **Crucial:** Must be the same for all containers (e.g., /opt/appdata) | | **PARENT\_INTERFACE** | **(Advanced)** Physical network card | Run: ip link or nmcli. (e.g., eth0, enp2s0) | | **SUBNET** | **(Advanced)** Your local IP range | e.g., 192.168.1.0/24 | | **GATEWAY** | **(Advanced)** Your router's IP address | e.g., 192.168.1.1 | #### โš ๏ธ Critical Advanced Networking Notes If you select ****MacVLAN** or ****IPvLAN** in the generator, you are moving away from "Standard" Docker networking. Pay attention to these "Gotchas": - ****Interface Precision:** The `PARENT_INTERFACE` is the physical port your cable is plugged into. If you use a placeholder like `eth0` while your real interface is `enp3s0`, the container will fail to launch with a "Link not found" error. - ****The Subnet Map:** Your `SUBNET` must accurately reflect your router's DHCP range. If your router hands out IPs like `10.0.0.X`, your subnet must be `10.0.0.0/24`. - ****Host Isolation (The "Invisible" Container):** By default, Linux prevents the Host OS from talking to a MacVLAN container. - - ****Result:** Your TV and Phone will see Plex, but the PC **running* Docker won't be able to access the Web UI at `localhost`. You'll need to use the container's specific IP or set up a bridge. - TL;DR = Just use a user defined bridge network (Default!) ### ๐Ÿ› ๏ธ Hardware Acceleration Check - **Intel/AMD:** Ensure your user is in the `render` or `video` group (Run: `groups`). - **NVIDIA:** Ensure you have the [**NVIDIA Container Toolkit**](https://corelab.tech/nvidiatoolkit/) installed on the host. The generator no longer uses `runtime: nvidia`, opting for the modern `deploy` resource reservation method. **FREE** access to the DUMB generator, just sign up and download your custom generated config!๐Ÿ‘‡ #### Join the Core Lab Inner Circle Instant access to all Core Lab Docker Generators!

It has a few pre-requisites though to get hardware transcoding working. ### **๐Ÿ“‹ The 2026 Hardware Transcoding Checklist** To ensure your DUMB stack doesn't just "fail over" to the CPU, run through these prerequisites for each hardware type. | Hardware Type | Host Driver Prerequisite | Container Device Mapping | Key Logic / Env Var | | -------------------- | --------------------------------- | ---------------------------------- | -------------------------------- | | **๐Ÿ”ต Intel QSV/Arc** | intel-media-driver \+ Kernel 6.2+ | /dev/dri/renderD128 | Ensure user is in render group | | **๐ŸŸข NVIDIA** | NVIDIA Proprietary Driver 550+ | *Managed by Toolkit* | runtime: nvidia is **mandatory** | | **๐Ÿ”ด AMD (Vulkan)** | mesa-va-drivers \+ vulkan-radeon | /dev/dri/renderD128 | Preferred for modern Jellyfin | | **๐Ÿ”ด AMD (OpenCL)** | rocm-opencl-runtime | /dev/dri/renderD128 **&** /dev/kfd | Required for legacy tone mapping | #### Hardware Transcoding Details ****๐Ÿ”ต Intel (QuickSync & Arc A-Series)** - ****Kernel Version:** You must be on ****Kernel 6.2+** for stable Arc support (Debian 13 / Ubuntu 24 / CachyOS handle this natively). - ****Drivers (Host):** Install `intel-media-driver` and `libva-utils`. - ****Permissions:** Your host user must be in the `render` group. - - **Check:* `ls -l /dev/dri/renderD128` (Verify it's owned by the `render` group). - ****BIOS:** "Internal Graphics" must be set to ****Enabled** (not Auto) if using the iGPU alongside a dGPU. ****๐ŸŸข NVIDIA (RTX / GTX / Quadro)** - ****Drivers (Host):** Proprietary drivers version ****545 or newer** installed on the host. - ****Toolkit:** [****NVIDIA Container Toolkit**](https://corelab.tech/nvidiatoolkit/) must be installed and configured (`nvidia-ctk runtime configure --runtime=docker`). - ****Compose:** The `runtime: nvidia` flag is the "Master Switch." Without it, environment variables do nothing. ****๐Ÿ”ด AMD (Radeon / APU)** - ****Drivers (Host):** `mesa-va-drivers` installed on the host. - ****VA-API Support:** Verify with `vainfo` on the host to ensure the entry-points for H.264/HEVC/AV1 are visible. - ****Permissions:** Host user must be in the `video` and `render` groups. ### **The "All-in-One" Universal H/W Transcode Optimized Compose** *Best for: Fresh installs. Includes Plex built-in. Modify file paths & user variables as applicable.* ๐Ÿ˜ฎ Change the docker networking to suit your needs! If unsure, leave to default bridge network, see more details on my [docker networking guide.](https://corelab.tech/setupcompose/#networking-configurations-and-types) ```YAML services: dumb: image: iampuid0/dumb:latest container_name: DUMB hostname: dumb stop_grace_period: 60s shm_size: 2g # Mandatory for Plex transcoder stability & large libraries stdin_open: true tty: true restart: unless-stopped environment: - TZ=America/Toronto - PUID=1000 # Change to your user - PGID=1000 # Change to your user # --- ๐ŸŸข NVIDIA GPU SECTION --- # Uncomment the lines below if using an NVIDIA GPU # - NVIDIA_VISIBLE_DEVICES=all # - NVIDIA_DRIVER_CAPABILITIES=all,video,compute,utility # --- ๐Ÿ”ด AMD RDNA 3/4 FIX --- # Only uncomment if your 7000/8000 series AMD card isn't recognized # - HSA_OVERRIDE_GFX_VERSION=11.0.0 volumes: - /opt/appdata/dumb/config:/config - /opt/appdata/dumb/log:/log - /opt/appdata/dumb/data:/data # ๐Ÿช„ THE MAGIC MOUNT: Required for Decypharr to propagate the FUSE mount - /opt/appdata/dumb/mnt/debrid:/mnt/debrid:rshared - type: tmpfs target: /transcode tmpfs: size: 4096000000 # ~4GB limit, adjust to your needs ports: - "3005:3005" # DUMB Dashboard - "32400:32400" # Plex Media Server - "9696:9696" # Prowlarr - "7878:7878" # Radarr - "8989:8989" # Sonarr - "8282:8282" # Decypharr devices: # โš ๏ธ MANDATORY: Required for FUSE-based debrid mounting - /dev/fuse:/dev/fuse:rwm # --- ๐Ÿ”ต INTEL ARC / QSV & ๐Ÿ”ด AMD --- # Precision mapping: renderD128 is usually the first GPU/iGPU. # Use renderD129 if the Arc card is your second device. - /dev/dri/renderD128:/dev/dri/renderD128 # --- ๐Ÿ”ด AMD LEGACY OPENCL --- # Uncomment if using older tone-mapping engines in Jellyfin/Plex # - /dev/kfd:/dev/kfd # --- ๐ŸŸข NVIDIA RUNTIME --- # Uncomment if using NVIDIA GPU - Requires nvidia-container-toolkit installed on the host OS # runtime: nvidia cap_add: - SYS_ADMIN # Critical for mounting debrid drives inside the container security_opt: - apparmor:unconfined # Necessary for mount propagation on Debian/Ubuntu ``` ### ๐Ÿ›ก๏ธ Final Sanity Check Before you `docker compose up -d`, double-check these three points on your host to ensure the "Laser-Guided" HWA actually hits the target: 1. **Group Permissions:** Run `groups $USER`. Ensure your user is in the `render` group (for Intel/AMD) or the `video` group. If not, run `sudo usermod -aG render,video $USER` and log out/in. This is the user that you're running DUMB as. Not your user you login as! 2. **Mount Point Existence:** Ensure `/opt/appdata/dumb/mnt/debrid` exists on your host *before* you start the container, or Docker might create it as a root-owned directory, breaking your mount permissions. If you followed the steps above to create your folders, this should be already done and ready to go. 3. **Intel Arc "Slot" Verification:** Run `ls -l /dev/dri`. If you see both `renderD128` (iGPU) and `renderD129` (Arc Card), make sure your Compose matches the specific card you want Plex/Jellyfin to use. #### ๐Ÿ› ๏ธ The Core Lab Settings Detailed These lines define how the container identifies itself and stays stable. - **`image: iampuid0/dumb:latest`**: Pulls the "All-in-One" DUMB image which contains Plex, Sonarr, Radarr, and more. - **`shm_size: 2g`**: Increases "Shared Memory." This is critical for Plex/Jellyfin. Without this, your library scans might crash or run incredibly slowly. - **`stop_grace_period: 60s`**: Gives the container a full minute to shut down gracefully. This prevents database corruption in Plex or Sonarr. ****๐ŸŒ Environment Variables (The Brains)** This section tells the container who you are and what features to turn on. - **`PUID/PGID=1000`**: Tells Docker to run as your specific Linux user so you don't run into "Permission Denied" errors on your files. ****๐Ÿ“‚ Volumes (The Storage)** Where your data lives on your computer. - **`/config`** **,** **`/log`** **,** **`/data`**: Standard folders for your settings and database. - **`/mnt/debrid`** **(The Magic Mount)**: This is the most important line. It links your host to the virtual drive created by Decypharr.****โš ๏ธ CRITICAL NOTE:** Do ****not** manually create sub-folders inside `mnt/debrid`. Decypharr needs this folder to be completely empty so it can "plug in" your virtual RealDebrid drive. ****๐Ÿ”Œ Ports (The Doors)** These allow you to access the web dashboards from your browser. - ****3005**: DUMB Dashboard (Your control center) - ****32400**: Plex - ****9696 / 7878 / 8989**: Prowlarr, Radarr, and Sonarr. - ****8282**: Decypharr (The tool that helps manage your Debrid downloads). ****๐ŸŽ๏ธ Devices & Hardware Acceleration** This gives the container permission to talk to your computer's hardware. - **`/dev/fuse`**: ****Mandatory for Zurg.** This allows the container to create a virtual hard drive. It is a much safer alternative to using `privileged: true`. - **`/dev/dri`**: This allows ****Intel or AMD** users to use "Hardware Transcoding." It lets your GPU handle the heavy lifting of video playback instead of your CPU. - **`cap_add: SYS_ADMIN`**: Gives the container the specific "manager" right it needs to mount the virtual drive. --- ## **๐Ÿ›ธPhase 3: Launching the Stackโ—** Navigate to the directory containing your `docker-compose.yml` file and launch everything. ```bash cd /opt/appdata docker compose up -d ``` **Wait Time:** Give it a minute or 2 to fire up. You can check on the live logs of any of your dockers by typing: `docker logs -f dumb` and see what it's doing. `CTRL-C` to drop out of that. Tip - you can run docker compose up -d && docker logs -f DUMB at once. This is what you should see: ![](https://corelab.tech/content/images/2026/05/DUMB-docker-startup-log-watch.webp) Now you can login to the dashboard and create your admin account. Open your browser and go to: `http://:3005` ![](https://corelab.tech/content/images/2026/05/DUMB-initial-webgui-onboarding.webp) Once you create your user, you'll immediately be brought to the **services selection dasboard**. You want to ensure once you've finished selecting things you click the "Apply recommendations" button which the drives the submenu below. ๐Ÿšง HIGHLY recommend you ****do not use Huntarr!** It's been found to be a vibe-coded giant [pile of security vulnerabilities](https://www.reddit.com/r/selfhosted/comments/1rckopd/huntarr%5Fyour%5Fpasswords%5Fand%5Fyour%5Fentire%5Farr%5Fstacks/?ref=corelab.tech) and blew up on Feb 23! ![](https://corelab.tech/content/images/2026/05/DUMB-Onboarding-select-services.webp) Scroll down and just ensure that the aarrs are selected. If you chose "Multiple quality tiers" above, you'll see 2 instances. Later I blew this away and just chose 1 by **un-selecting** that. I find 1 instance of Radarr & Sonarr is perfect. ![](https://corelab.tech/content/images/2026/05/DUMB-onboarding-service-selection-pt2.webp) I chose to use 1 instance, not a separated. ![](https://corelab.tech/content/images/2026/05/DUMB-decypharr-onboarding-guide.webp) ![](https://corelab.tech/content/images/2026/05/DUMB-onboarding-confirmation-pre-install-checklist.webp) Now you will continue to the optional services selection, and configuring each service.

They are referenced in full at the complete compose example above. ### **Option 1: Intel QuickSync (N100 / N95 / Core i3/i5/i7)** *The most common option for Mini PCs.* ```yaml devices: - /dev/dri:/dev/dri # Maps the iGPU to the container ``` ### **Option 2: NVIDIA (RTX / GTX / Quadro)** *Requires the* [*Nvidia Container Toolkit*](https://corelab.tech/nvidiatoolkit/) *installed on your host OS.* ```yaml runtime: nvidia environment: - NVIDIA_VISIBLE_DEVICES=all - NVIDIA_DRIVER_CAPABILITIES=all ``` ### **Option 3: AMD Radeon** ```yaml devices: - /dev/dri:/dev/dri # For VAAPI - /dev/kfd:/dev/kfd # For OpenCL (Optional but recommended) ``` --- ## **โš™๏ธ Phase 4: Configuring Services** Since DUMB is a "Mega-Container," your apps (Radarr, Sonarr, Decypharr) are already installed - they just need to be woken up & interconnected. Login to each of the services like Radarr, Sonarr, Prowlarr and configure them one by one to talk to each other, and to Decypharr. You initially access them via that embedded UI, or if you remember the ports, use those like `http://yourserverip:8989` for Sonarr, `7878` for Radarr etc.. I configure them in this order, it's logical to me but can be done in anyway: 1. **Profilarr** (Quality profiles): `http://YOUR-SERVER-IP:6868` 2. **Prowlarr** (Trackers/sources): `http://YOUR-SERVER-IP:9696` 3. **Sonarr, Radarr** (TV, Movies): `http://YOUR-SERVER-IP:8989`, `http://YOUR-SERVER-IP:7878` 4. **Plex/Jellyfin** (Media playing server): `http://YOUR-SERVER-IP:32400/web`, `http://YOUR-SERVER-IP:8096` 5. **Seerr** (Media request service): `http://YOUR-SERVER-IP:5055` ๐Ÿซ  If you enabled additional services in your DUMB compose, you may need to add their ports to your variables and restart dumb before you can directly access them! If they load, you are ready to link them! #### ****The Media Request Flow from Seerr to Playback** How it flows! 1. ****You Request:** (via Seerr or Plex Watchlist) 2. ****The Brains:** Radarr/Sonarr grab the request. 3. ****The Search:** Prowlarr finds the torrent. 4. ****The Trick:** Decypharr "downloads" it instantly to Real-Debrid. 5. ****The Mount:** Decypharr now does this for you as well. 6. ****Playback**: Plex or Jellyfin show the new media ready and playable! ### **Step 4.1: Configure Prowlarr (The Search Engine)** Radarr needs a way to find torrents. We use Prowlarr for this. 1. Go to **Prowlarr** (`:9696`) and create your login. 2. **Add Indexers:** Go to **Indexers > Add New**. - For beginners, search for "Public" trackers like *1337x*, *TorrentGalaxy*, or *MagnetDL*. Filter by selecting torrent, english, and movies/tv. - Add a pile, at least 5. - **Make sure to add tag**: `decypharr` on all of themโ— - If you have flaresolvarr running, you can add it here as well. Not part of this guide as it's not part of the DUMB stack. ![](https://corelab.tech/content/images/2026/05/Prowlarr-add-indexer-with-decypharr-tag.webp) Add that Tag!!! 1. **Link to Apps:** Go to **Settings > Apps**. - Click `+` and choose **Radarr**. - **Prowlarr Server:** `http://localhost:9696` - **Radarr Server:** `http://localhost:7878` - **API Key:** Copy from Radarr (Settings > General). - Repeat for **Sonarr** (`:8989`). ![Now Radarr knows how to search.](https://corelab.tech/content/images/2026/05/Radarr-adding-decypharr.webp) **Now Radarr knows how to search.* ### **Step 4.2: Prowlarr - Your Custom "TRaSH" like Profiles** Here's where you get unrelenting quality profiles slapped into Sonarr & Radarr *automatically.* Take a moment here to explore Prowlarr a bit and familiarize yourself with all the profiles.

Radarr/Sonarr think they are talking to a QBitTorrent client, but they are actually talking to Decypharr, which instantly caches the file on Real-Debrid. 1. Open **Radarr** (`http://YOUR-IP:7878`) or **Sonarr** (`http://YOUR-IP:8989`). 2. Go to **Settings > Download Clients**. 3. Click **+** and choose **QBitTorrent**. 4. **Name:** `Decypharr` 5. **Host:** `localhost` (They live in the same container!) 6. **Port:** `8282` (This is Decypharr's internal port). 7. **Username:** `admin` 8. **Password:** `adminadmin (change this!)` 9. **Category (Optional):** `movies` (for Radarr) or `tv` (for Sonarr). 10. **Test & Save.** ![](https://corelab.tech/content/images/2026/05/Sonarr-adding-decypharr-to-downloaders.webp) ### **4.4 Step-by-Step Bazarr Setup** 1. **Access Bazarr:** Go to `bazarr.yourdomain.com`. 2. **Connect Radarr and Sonarr:** - Go to **Settings โ†’ Sonarr** and **Settings โ†’ Radarr**. - Input the URL (e.g., `http://sonarr:8989`) and API Key for each app. - Test and Save. 3. **Media Path Check:** Bazarr automatically inherits the correct paths from Radarr/Sonarr, but it's good practice to verify under **Settings โ†’ Media Management** that it is also using the **`/mnt/debrid`** path. --- ### **4.5 Connecting Media Servers Plex or Jellyfin** Login to whichever one you chose and add their media paths. 1. For **Plex**, you'd navigate to `http://:32400/web` to begin it's setup. 1. Login with your Plex account from https://plex.tv and; 1. Follow it's setup wizard by first naming your server. 1. I'd recommend logging in directly and signing in with your plex account this way, then you ***don't have to mess around with claim tokens*** or the dumb.config JSON file. 2. For **Jellyfin**, you'd navigate to `http://YOUR-SERVER-IP:8096` to begin it's setup. Similar idea, follow the setup wizard. ### Note on Local Network Discovery w/Plex or Jellyfin: ๐Ÿ’ฅ While mapping `32400:32400` allows you to access the web interface, ****Bridge Mode breaks local discovery (DLNA/Gdm)** because the container is on a different subnet (e.g., docker bridge net `172.18.x.x`) than your home LAN (`192.168.1.x`). ****For Plex:** Go to ****Settings -> Network -> LAN Networks** and add your home subnet (e.g., `192.168.1.0/24`). This forces Plex to treat your local devices as local, even if the discovery broadcast fails. ****For Jellyfin:** Go to ****Dashboard -> Networking -> LAN Networks** and do the same. ![](https://corelab.tech/content/images/2026/05/Plex-and-Jellyfin-network-settings.webp) #### 4.6 Adding the "Cloud" Libraries This is the moment of truth. Now that things are fired up, and Decypharr mounted your cloud drive to `/opt/appdata/dumb/mnt/debrid/decypharr/realdebrid` it's time to make a couple more folders and own them. You'll only need to create these if sonarr & radarr don't automatically make the folders on their own. By default if you don't make these directories, upon first addition of media in sonarr or radarr, they *should* make default folders in a slightly different path: `dumb/mnt/debrid/decypharr_symlinks/radarr-debrid` and `dumb/mnt/debrid/decypharr_symlinks/sonarr-debrid`. But at first they didn't for me, so I made more 'meaningful' names. Optional Step, manual tv and movies folders: ```bash 1. Create new directory skeleton sudo mkdir -p /opt/appdata/dumb/debrid/decypharr_symlinks/{tv,movies} # 4. Set Ownership (CRITICAL) sudo chown -R mediauser:mediauser /opt/appdata/dumb/debrid/decypharr_symlinks/ sudo chmod -R 755 /opt/appdata/dumb/debrid/decypharr_symlinks/ ``` #### WHAT the F is going on with these foldersโ‰๏ธ Decypharr mounts your "cloud" cache drive to `dumb/mnt/debrid/decypharr/realdebrid` on your local system. Once a "download" is completed, it symlinks it to `dumb/mnt/debrid/decypharr_symlinks/tv or movies` ! > Now in **Plex or Jellyfin**, create new **libraries** and point them at your new media folders! Reminder of the paths: ๐Ÿ˜€ /opt/appdata/dumb/mnt/debrid/decypharr\_symlinks/tv and /opt/appdata/dumb/mnt/debrid/decypharr\_symlinks/movies ๐Ÿ’ก If your Plex or Jellyfin is running in its own Docker container, you ****MUST** modify its configuration to ensure it has read access to the debrid mount. This single step is the ****key** to the entire integration. You just need to make sure your media server can see the debrid mount point and content! --- ## **Step 5: Reverse Proxy Setup (Secure Remote Access)** Since you are a self-hoster, you likely have a proxy running (SWAG, Caddy, or Nginx Proxy Manager). If not, hop over to see my [SWAG guide](https://corelab.tech/swag-reverse-proxy-guide/). Here is a rough guide for linking your apps to your custom domain, e.g., `radarr.yourdomain.com`. Going into detail on this topic is out of scope for this guide, as each reverse proxy could be multiple blog posts in itself! I only recommend publicly exposing absolutely what you *need* to. Such as only Jellyseerr; VPN inbound for everything else. I also don't recommend putting Plex behind a reverse proxy, but Jellyfin **requires one**. ### **General Reverse Proxy Steps:** 1. **DNS Records:** In your domain registrar's settings, create **A Records** for your subdomains (e.g., `radarr`, `sonarr`, `prowlarr`, etc.) pointing to your server's public IP address. 2. **Proxy Configuration:** In your proxy application's dashboard (NPM) or config files (SWAG/Caddy): - **Forward Hostname/IP:** Use your Docker host's internal IP (e.g., `192.168.1.100`) or the container name if they're on the same Docker network (e.g., `radarr`). - **Forward Port:** Use the internal container ports defined in the `ports:` section above (e.g., `7878` for Radarr, `9696` for Prowlarr, `3005` for DUMB). - **SSL:** Ensure you activate SSL/TLS to get that secure green lock icon in your browser. | App | Internal Port | Suggested Subdomain | | | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Address each error 1 by 1 or slap a comment down below ;)๐Ÿšจ The "Showstoppers" (Plex Won't Start)Problem: Plex is stuck on "Waiting for mounts..." or "Service Failed"The Cause: Rclone (inside Decypharr) is a perfectionist. It requires its mount point to be a completely empty directory. If you manually created folders inside /mnt/debrid/realdebrid/ on your host BEFORE it created them, Decypharr/rclone will refuse to mount, and Plex will wait forever.The Fix: 1\. Stop the container: docker compose down. 2\. Clean the host folder: sudo rm -rf /opt/appdata/dumb/mnt/debrid/\*. 3\. Restart: docker compose up -d. Let the container create the sub-folders for you!Problem: Rclone (inside Decypharr, check logs) isn't starting or FUSE errors in logsThe Cause: Missing permissions or drivers on your host OS.The Fix: Ensure you have libfuse2 installed on your host (Run: sudo apt update && sudo apt install libfuse2 -y). Also, double-check that your RD\_API\_KEY is correct and has no extra spaces.๐Ÿ“‚ Library & Mapping IssuesProblem: "Radarr says the root folder is missing!"The Cause: The container likely started before the virtual drive was fully mounted.The Fix: Check your Docker logs (docker logs DUMB). Is Zurg finished mounting? Once the logs say the mount is ready, simply Restart Radarr inside the DUMB dashboard or restart the whole container.Problem: "Plex isn't finding files."The Cause: Permission mismatch or incorrect volume mapping.The Fix: Ensure your PUID and PGID in the Compose file match your host user (type id in your terminal to check). Also, verify your volume mapping is exactly \- /opt/appdata/dumb/mnt/debrid:/mnt/debrid:rshared.Problem: Prowlarr is running, but Radarr and Sonarr are empty!The Fix: Prowlarr needs to "push" the settings. Go to the Prowlarr UI (port 9696), navigate to Settings > Apps, and click the Sync App Indexers button (the refresh icon).โšก Performance & OptimizationProblem: "4K Movies are Buffering!"The Fix: You likely missed the Golden Flags. Ensure your RCLONE\_MOUNT\_OPTIONS include \--vfs-read-ahead 256M. This forces the server to buffer the video into your RAM ahead of time so the stream doesn't stutter.Problem: Downloads just sit at "0%" or "Stalled."The Fix: Check the Decypharr dashboard (port 8282). It might need you to re-verify your RealDebrid connection or check for API rate limits.Still stuck? Check out the official DUMB FAQ for deep-dive technical support.Frequently Asked QuestionsWhat is the DUMB stack exactly?DUMB stands for Debrid Unlimited Media Bridge. It is a Docker-based stack that uses tools such as Zurg, Rclone, and Decypharr to mount your Real-Debrid library as a virtual drive.To Plex or Jellyfin, that mounted drive looks like a normal local media folder even though the content is actually stored remotely in your Real-Debrid account.The advantage is that you can stream extremely large libraries without buying more hard drives.DUMB is usually the best option if:You are starting from scratchYou want an all-in-one stackYou do not already have an existing Plex or Jellyfin serverWhat is the difference between DUMB and DMB?DUMB and DMB both use Real-Debrid and Zurg, but they are intended for different users.๐Ÿ’กDMB is depreciated by the dev! DUMB is the project to go for and is modular.DUMB is a complete stack with Plex, Zurg, Decypharr, and related services includedDMB is more modular and is designed for people who already have Plex or Jellyfin runningChoose DUMB if you want the easiest setup.Choose DMB if you already have an existing media server and only want to add Real-Debrid support.Will Real-Debrid ban me for using Plex or Jellyfin?Only if you leave the wrong media analysis settings enabled.Real-Debrid can temporarily or permanently ban accounts when Plex or Jellyfin rapidly scans files, generates thumbnails, analyzes intros, or performs deep media analysis. To Real-Debrid, this can look like a DDoS attack.In Plex, you should disable:Generate video preview thumbnailsGenerate chapter thumbnailsDetect introsAnalyze audio tracksExtensive library scansIn Jellyfin, disable scheduled image extraction and aggressive metadata scanning.If you use the recommended settings from this guide, most users never have issues.Why is my Plex library empty even though Zurg/Decypharr is mounted?If Zurg/Rclone/Decypharr mount appears to be mounted but Plex shows an empty library, the most common causes are:Plex is pointed at the wrong folderRclone or Zurg mounted after Plex startedThe Docker mount is missing :rsharedPermissions are incorrectYour Real-Debrid account has no cached files yetTo fix it:Confirm the mount contains files from inside the containerRestart Plex after Zurg and Rclone are runningVerify your Docker volume uses :rsharedCheck that Plex is pointed at the mounted /mnt/zurg or equivalent folderWhy is my DUMB / Zurg / Rclone / Decypharr mount showing as an empty folder?This usually happens because of one of three issues:Missing FUSE supportIncorrect Docker mount optionsWrong Real-Debrid API keyMake sure:libfuse2 is installed on the hostYour Docker volume is configured with :rsharedRclone is successfully mountedYour Real-Debrid API key is entered correctlyYou can also test the mount manually:ls /mnt/zurg | | | | If the folder is empty there too, the problem is with Zurg or Rclone rather than Plex.Radarr or Sonarr says the root folder does not exist. How do I fix it?This happens when Radarr or Sonarr is using a different path than Plex or Zurg.All containers must use the same mounted path.For example:/mnt/zurg/movies | | | | | /mnt/zurg/tv | | | | | If Plex sees /data/movies but Radarr sees /mnt/zurg/movies, imports will fail.The easiest fix is to standardize all containers around the exact same Docker volume mapping.Why does Plex/Jellyfin buffer on 4K Remux files?Buffering is usually caused by one of these issues:ISP throttlingSmall Rclone cache settingsPlex trying to transcode instead of direct playSlow internet upload or download speedThe best fixes are:Increase \--vfs-read-ahead to at least 256MEnable \--buffer-size 256MUse Direct Play whenever possibleDisable advanced security features on Rogers Ignite or Bell Fibe routersUse a wired Ethernet connection for the serverIf you are using an older CPU or a smaller GPU, 4K transcoding may also be too demanding.Why do 4K streams work in a browser but not in Plex?If a Real-Debrid link works directly in the browser but buffers or fails in Plex, Plex is usually trying to transcode the file.This often happens because:The client device does not support the codecSubtitles are forcing a transcodePlex is set to stream at a lower qualityTo fix this:Set Plex quality to OriginalDisable image-based subtitles such as PGSUse a client that supports HEVC and HDR nativelyDo I need a VPN for the DUMB or Real-Debrid setup?No. Real-Debrid traffic is already encrypted over HTTPS.Using a VPN can actually create problems because Real-Debrid may detect your account being used from multiple IP addresses and temporarily block access.For most users, a VPN is unnecessary and can make the setup less reliable.If you're in a country where Real-Debrid is blocked, you may then need a VPN!Can I use Plex with Real-Debrid without Docker?Technically yes, but it is much harder.The easiest and most reliable method is to use Docker because DUMB, DMB, Zurg, and Decypharr are all designed around containerized deployments.Without Docker, you would need to manually configure:Rclone mountsBackground servicesStartup scriptsPermissions and FUSEUnless you already know Linux extremely well, Docker is the better approach.How do I prevent Real-Debrid account bans?The most important rule is: do not let Plex or Jellyfin aggressively scan the mounted library.You should:Disable thumbnail generationDisable intro detectionTurn off deep analysisAvoid refreshing the entire library constantlyLimit the number of simultaneous usersYou should also avoid switching between multiple IP addresses rapidly.Does Real-Debrid work with multiple Plex or Jellyfin users?Yes, but there are limits.A few simultaneous users usually work fine. However, if many people are streaming at once or if several people trigger large library scans simultaneously, you are more likely to hit Real-Debrid rate limits which are 200 requests/min.For a small family or a few friends, the setup is usually fine.Can I use Jellyfin instead of Plex?Yes! Jellyfin works very well with Decypharr and Real-Debrid.However, you still need to disable:Preview image generationDeep media analysisFrequent scheduled scansOtherwise Jellyfin can cause the same Real-Debrid bans as Plex.Can I run this on a low-power mini PC like an Intel N100?Yes. One of the biggest advantages of a Plex + Real-Debrid setup is that you do not need large local storage or a powerful CPU.An Intel N100 mini PC can run:Plex or JellyfinZurgDecypharrRadarr and Sonarrvery comfortably, especially if most playback is Direct Play.If you plan to transcode multiple 4K streams, however, you may want something more powerful.๐ŸŽ†Congratulations again!
