# 114 — Koillection Deployment Guide
> Status: **PLANNED** — not yet deployed
> CT ID: 114 · IP: 192.168.1.114
> Domain: `collections.spendlik.sk`
> Last updated: 2026-07-03

## Overview
Koillection is a self-hosted collection manager for tracking physical collections of any kind. No pre-built metadata scrapers — metadata is added freely per item, with custom fields via templates. MIT licensed.
**Collections planned for this instance:**
- 🚗 Hot Wheels (series, year, colour, condition, variants)
- 🧱 LEGO (set number, theme, piece count, minifigures, completion status)
- 🦇 Batmobiles (source media, scale, manufacturer, condition)
- 📚 Comics (title, issue, publisher, language, condition)
- 📄 Paper Models (designer, scale, subject, format — physical printed copies)
Stack: `koillection/koillection` (PHP/Symfony + Vue.js) + PostgreSQL 16. Uploads (item photos) bind-mounted to NAS for data safety.

## Resource Allocation
| Resource | Allocation |
|---|---|
| **CT ID** | 114 |
| **IP** | 192.168.1.114 |
| **CPUs** | 1 |
| **RAM** | 512 MB |
| **Disk** | 8 GB (app + DB only; photos on NAS) |
| **Template** | Debian 13 (trixie) |
| **Privileged** | Yes (Docker requires it) |
| **Nesting** | Enabled (`features: nesting=1`) |
---
## NAS Mount Planning
Photos uploaded to Koillection land in `/uploads` inside the container. This will be bind-mounted from the NAS at:
```
/volume1/proxmox/data/koillection/uploads
```
Create this directory on the NAS before deployment:
```bash
# On the Synology NAS (SSH or File Station)
mkdir -p /volume1/proxmox/data/koillection/uploads
```
> ⚠️ The NAS path follows the same convention as Paperless (`/volume1/proxmox/data/<service>`). Be consistent.
---
## Phase 1 — Create LXC Container
In the Proxmox web UI terminal on the host:
```bash
pct create 114 local:vztmpl/debian-13-standard_13.0-1_amd64.tar.zst \
--hostname koillection \
--cores 1 \
--memory 512 \
--swap 512 \
--rootfs local-lvm:8 \
--net0 name=eth0,bridge=vmbr0,ip=192.168.1.114/24,gw=192.168.1.1 \
--unprivileged 0 \
--features nesting=1 \
--ostype debian \
--start 1
```
Enter the container:
```bash
pct enter 114
```
---
## Phase 2 — Base Setup
```bash
apt update && apt upgrade -y
apt install -y nano curl ca-certificates gnupg lsb-release
```
---
## Phase 3 — Install Docker
```bash
install -m 0755 -d /etc/apt/keyrings
curl -fsSL https://download.docker.com/linux/debian/gpg | gpg --dearmor -o /etc/apt/keyrings/docker.gpg
chmod a+r /etc/apt/keyrings/docker.gpg
echo \
"deb [arch=$(dpkg --print-architecture) signed-by=/etc/apt/keyrings/docker.gpg] \
https://download.docker.com/linux/debian \
$(lsb_release -cs) stable" | tee /etc/apt/sources.list.d/docker.list > /dev/null
apt update
apt install -y docker-ce docker-ce-cli containerd.io docker-compose-plugin
```
Verify:
```bash
docker run --rm hello-world
```
---
## Phase 4 — NAS Bind Mount
Add the NAS uploads path as a Proxmox bind mount. Exit the container first:
```bash
exit
```
On the Proxmox host:
```bash
pct set 114 --mp0 /mnt/pve/nas/proxmox/data/koillection/uploads,mp=/uploads
```
> ⚠️ Adjust the host-side NAS path to match how the NAS is mounted on the Proxmox host. Verify the mount point with `ls /mnt/pve/` or check `pvesm status` first. If the NAS is not yet mounted at the host level, add it following the same pattern used for CT 111 (Paperless).
Re-enter the container and verify the mount is visible:
```bash
pct enter 114
ls /uploads
```
---
## Phase 5 — Deploy Koillection
```bash
mkdir -p /opt/koillection
cd /opt/koillection
nano .env
```
Paste (fill in a strong password for `DB_PASSWORD`):
```env
DB_DRIVER=pdo_pgsql
DB_NAME=koillection
DB_HOST=db
DB_PORT=5432
DB_USER=koillection
DB_PASSWORD=CHANGE_ME
DB_VERSION=16
APP_ENV=prod
APP_DEBUG=0
APP_SECRET=CHANGE_ME_32CHAR_RANDOM_STRING
PHP_TZ=Europe/Bratislava
HTTPS_ENABLED=0
```
> Generate `APP_SECRET` with: `openssl rand -hex 16`
```bash
nano docker-compose.yml
```
Paste:
```yaml
services:
koillection:
image: koillection/koillection:latest
container_name: koillection
restart: unless-stopped
ports:
- "8080:80"
env_file:
- .env
volumes:
- /uploads:/uploads
depends_on:
db:
condition: service_healthy
db:
image: postgres:16
container_name: koillection-db
restart: unless-stopped
env_file:
- .env
environment:
- POSTGRES_DB=${DB_NAME}
- POSTGRES_USER=${DB_USER}
- POSTGRES_PASSWORD=${DB_PASSWORD}
volumes:
- ./volumes/postgresql:/var/lib/postgresql/data
healthcheck:
test: ["CMD", "pg_isready", "-q", "-d", "koillection", "-U", "koillection"]
timeout: 45s
interval: 10s
retries: 10
```
Start:
```bash
docker compose up -d
docker compose logs -f
```
Wait until the koillection container logs settle (Symfony app startup). Then verify locally:
```bash
curl -s http://localhost:8080 | grep -i koillection
```
---
## Phase 6 — nginx Reverse Proxy (CT 101)
Enter CT 101:
```bash
pct enter 101
nano /etc/nginx/sites-available/koillection
```
Paste:
```nginx
server {
listen 80;
server_name collections.spendlik.sk;
location / {
proxy_pass http://192.168.1.114:8080;
proxy_set_header Host $host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header X-Forwarded-Proto $scheme;
client_max_body_size 20M;
}
}
```
> `client_max_body_size 20M` — item photos can be large. Adjust upward if needed.
Enable and reload:
```bash
ln -s /etc/nginx/sites-available/koillection /etc/nginx/sites-enabled/
nginx -t && systemctl reload nginx
```
---
## Phase 7 — SSL Certificate
Still in CT 101:
```bash
certbot --nginx -d collections.spendlik.sk
```
> ⚠️ Always inspect the config after certbot:
```bash
cat /etc/nginx/sites-available/koillection
```
Check for duplicate `server_name` directives and missing closing braces. Fix manually if needed.
Also set `HTTPS_ENABLED=1` in `/opt/koillection/.env` in CT 114, then restart:
```bash
# In CT 114
cd /opt/koillection
nano .env # set HTTPS_ENABLED=1
docker compose restart koillection
```
---
## Phase 8 — DNS Record
In WebSupport admin panel:
1. Add A record: `collections` → current public IP
2. **Check both DNS management pages**
3. Note the numeric record ID
4. Add to `00_index.md` DNS table
---
## Phase 9 — DDNS Updater (CT 108)
Enter CT 108, add `collections.spendlik.sk` to `/usr/local/bin/ddns-update.sh` using the record ID from Phase 8, following the existing script pattern.
---
## Phase 10 — Authelia Protection (CT 102)
Enter CT 102, edit `/etc/authelia/configuration.yml`. Add to `access_control.rules`:
```yaml
- domain: collections.spendlik.sk
policy: two_factor
```
> Koillection has its own internal login system. Authelia adds a second layer before users even reach the login page. Since this is a personal single-user instance, you may prefer Authelia bypass and rely on Koillection's own login instead — your call.
Restart Authelia after editing:
```bash
docker compose restart
```
Add the Authelia middleware to the nginx vhost in CT 101 (follow the pattern from other protected services).
---
## Phase 11 — First Login & Initial Setup
Open `https://collections.spendlik.sk` from mobile data (hairpin NAT — never test from LAN).
On first load, Koillection will prompt you to create an admin account. Do so, then:
1. Set your timezone to `Europe/Bratislava` in profile settings
2. Set the display currency if tracking purchase values
3. Set visibility defaults (private by default is fine for a personal instance)
---
## Phase 12 — Collection Setup
Recommended collection structure. Create each as a top-level Collection:
### 🚗 Hot Wheels
Suggested item fields (via Template):
- Series / Line
- Year of release
- Colour
- Casting name
- Country of manufacture
- Condition (Mint / Good / Played)
- Treasure Hunt (yes/no)
### 🧱 LEGO
Suggested item fields:
- Set number
- Theme
- Sub-theme
- Piece count
- Minifigure count
- Year
- Completion status (Sealed / Built / Parts only)
- Instruction booklet present (yes/no)
> 💡 The set number field makes cross-referencing with kocka-novinky.sk and Brickset API straightforward.
### 🦇 Batmobiles
Suggested item fields:
- Source (Film / TV / Comics / Game)
- Year of appearance
- Manufacturer (Hot Wheels / Corgi / LEGO / custom)
- Scale
- Condition
### 📚 Comics
Suggested item fields:
- Title / Series
- Issue number
- Publisher
- Language
- Year
- Condition (Mint / Very Good / Good / Fair)
- Story arc
### 📄 Paper Models (physical hardcopy)
Suggested item fields:
- Designer / Publisher
- Subject (aircraft, ship, building…)
- Scale
- Format (magazine supplement / standalone / kit)
- Build status (Unbuilt / Built / Display)
> 💡 Tags are cross-collection in Koillection — tag items with `#display`, `#wishlist`, `#for-sale` etc. to group across all five collections at once.
---
## Backup
The only things that need backing up:
1. **PostgreSQL database** — contains all collection metadata
2. **NAS uploads directory** — contains all item photos (already on NAS, covered by NAS backup)
Add a daily DB dump to cron in CT 114:
```bash
crontab -e
```
Add:
```cron
0 3 * * * docker exec koillection-db pg_dump -U koillection koillection > /opt/koillection/backups/koillection-$(date +\%Y\%m\%d).sql 2>/dev/null
```
```bash
mkdir -p /opt/koillection/backups
```
> ⚠️ Always back up the database before upgrading Koillection — the developer notes that data migrations can occasionally have edge cases.
---
## Gotchas
| Issue | Fix |
|---|---|
| Photos not saving | Verify `/uploads` bind mount is writable inside the container |
| App not starting | Check `docker compose logs koillection` — usually a DB connection issue on first boot |
| certbot corrupts nginx config | Always inspect after issuance |
| Large photo uploads rejected | Increase `client_max_body_size` in nginx vhost |
| HTTPS redirect loop | Set `HTTPS_ENABLED=1` in `.env` and restart the koillection container after SSL is in place |
