*Arr Stack Setup Overview

Overview

The stack consists of:

Core Principles

Single data root in container: /data Config isolation in container: /config UID/GID consistency: 1000:1000 No user: overrides in containers

Configuration Management

Each service maintains isolated configuration directories:

/opt/docker/media/config/
├── radarr/
├── sonarr/
├── prowlarr/
├── qbittorrent/
└── jellyseerr/

The docker-compose.yml file and all persistent configurations are co-located in this structure for maintainability and portability.

Network Exposure Policy

Only one service is intended for external access:

Jellyseerr (user-facing interface)

All other services are restricted to internal network access only:

  • Radarr (administration only)
  • Sonarr (administration only)
  • Prowlarr (administration only)
  • qBittorrent (administration only)

This reduces attack surface and prevents unintended external exposure of management tools.

Key Setup Commands

Start stack

docker compose up -d

Stop stack

docker compose down

Restart a service

docker restart radarr

View logs

docker compose logs -f sonarr

Permission Management

To ensure container access consistency across all services:

Fix configuration ownership

sudo chown -R 1000:1000 /opt/docker/media/config

Fix media library ownership

sudo chown -R 1000:1000 /mnt/BonusDisk/JellyfinMedia/Streaming

These commands ensure all containers can properly read and write to both configuration and media directories.

Container Inspection & Debugging

Inspect container configuration

docker inspect radarr

This is used to verify:

  • volume mappings
  • environment variables
  • network configuration
  • runtime state

Summary

This stack is designed for:

  • full automation of media acquisition
  • strict separation between configuration and media
  • consistent permission handling via UID/GID alignment
  • minimal external exposure for security
  • predictable and reproducible container behavior

Once correctly configured, the system operates without manual intervention, automatically managing download, import, and organization workflows across both movies and TV series.
