# *Arr Stack Setup Overview

## Overview
4
5
The stack consists of:
6
7
- [Radarr](https://radarr.video) — movies
8
- [Sonarr](https://sonarr.tv) — TV series
9
- [Prowlarr](https://prowlarr.com) — indexers
10
- [qBittorrent](https://www.qbittorrent.org) — downloads
11
- [Jellyseerr](https://docs.seerr.dev) — request UI!

## Core Principles
17
Single data root in container: `/data`
18
Config isolation in container: `/config`
19
UID/GID consistency: `1000:1000`
20
No `user:` overrides in containers
21
22
## Configuration Management
23
24
Each service maintains isolated configuration directories:
25
26
```
27
/opt/docker/media/config/
28
├── radarr/
29
├── sonarr/
30
├── prowlarr/
31
├── qbittorrent/
32
└── jellyseerr/
33
```
34
35
The docker-compose.yml file and all persistent configurations are co-located in this structure for maintainability and portability.
36
37
## Network Exposure Policy
38
39
Only one service is intended for external access:
40
41
[Jellyseerr](seerr.lucjans26.com) (user-facing interface)
42
43
All other services are restricted to internal network access only:
44
45
- Radarr (administration only)
46
- Sonarr (administration only)
47
- Prowlarr (administration only)
48
- qBittorrent (administration only)
49
50
This reduces attack surface and prevents unintended external exposure of management tools.

## Key Setup Commands
54
Start stack
55
```
56
docker compose up -d
57
```
58
Stop stack
59
```
60
docker compose down
61
```
62
Restart a service
63
```
64
docker restart radarr
65
```
66
View logs
67
```
68
docker compose logs -f sonarr
69
```
70
---
71
## Permission Management
72
73
To ensure container access consistency across all services:
74
75
### Fix configuration ownership
76
```
77
sudo chown -R 1000:1000 /opt/docker/media/config
78
```
79
80
### Fix media library ownership
81
```
82
sudo chown -R 1000:1000 /mnt/BonusDisk/JellyfinMedia/Streaming
83
```
84
85
These commands ensure all containers can properly read and write to both configuration and media directories.
86
87
## Container Inspection & Debugging
88
### Inspect container configuration
89
```
90
docker inspect radarr
91
```
92
93
This is used to verify:
94
95
- volume mappings
96
- environment variables
97
- network configuration
98
- runtime state
99
100
## Summary
101
102
This stack is designed for:
103
104
- full automation of media acquisition
105
- strict separation between configuration and media
106
- consistent permission handling via UID/GID alignment
107
- minimal external exposure for security
108
- predictable and reproducible container behavior
109
110
Once correctly configured, the system operates without manual intervention, automatically managing download, import, and organization workflows across both movies and TV series.
