QRknit — Installation & Configuration

Prerequisites

Docker installed and running
A domain or subdomain pointed at your server (for public access)

Generate a strong SECRET_KEY before you begin:

python3 -c "import secrets; print(secrets.token_hex(32))"

Option A — Docker run (quickest)

1. Get the source

git clone https://git.qrknit.com/qrknit.git
cd qrknit

2. Build the image

docker build -t qrknit:latest .

3. Run the container

docker run -d \
  --name qrknit \
  --restart unless-stopped \
  -p 5000:5000 \
  -v qrknit-data:/app/data \
  -e BASE_URL=https://yourdomain.com \
  -e APP_NAME=My.Links \
  -e SECRET_KEY=your-generated-key-here \
  -e ADMIN_PASSWORD=your-strong-password \
  qrknit:latest

Open http://localhost:5000 (or your domain) and log in with admin / your ADMIN_PASSWORD.

Option B — Docker Compose

1. Get the source

git clone https://git.qrknit.com/qrknit.git
cd qrknit

2. Edit docker-compose.yml — set at minimum:

- BASE_URL=https://yourdomain.com
- APP_NAME=My.Links
- SECRET_KEY=your-generated-key-here
- ADMIN_PASSWORD=your-strong-password

3. Build and start

docker compose up -d --build

Option C — Unraid (fresh install)

Step 1 — Get the source onto Unraid

Open the Unraid terminal and run:

cd /mnt/user/appdata
git clone https://git.qrknit.com/qrknit.git qrknit-src  # credentials provided with your Pro/Team licence

Or upload the source files manually to /mnt/user/appdata/qrknit-src/.

Step 2 — Build the image

cd /mnt/user/appdata/qrknit-src
docker build -t qrknit:latest .

Private instance access (source repository credentials and licence key) is included with Pro and Team plans. Contact support if you have not received yours.

Step 3 — Add the container in the Unraid Docker UI

Go to Docker tab → Add Container and fill in:

Field	Value
Name	`qrknit`
Repository	`qrknit:latest`
Network Type	`br0` (macvlan) or `Bridge`
Port Mapping	Host `5000` → Container `5000` (not needed for macvlan)
Path (Volume)	Host `/mnt/user/appdata/qrknit` → Container `/app/data`

Add the following Environment Variables:

Variable	Value	Notes
`BASE_URL`	`https://yourdomain.com`	Your public domain or subdomain
`APP_NAME`	`My.Links`	Display name shown in the UI — names with a dot (e.g. `to.mysite.io`) are split and styled automatically
`SECRET_KEY`	(generated above)	Required — signs session cookies
`ADMIN_PASSWORD`	(your password)	Required — admin account password
`ADMIN_USERNAME`	`admin`	Admin username (default: `admin`)
`COOKIE_SECURE`	`false`	Keep `false` behind Cloudflare or NPM. Set `true` only if Flask receives HTTPS directly.
`DEBUG`	`false`	Keep `false` in production

Click Apply.

Step 4 — Set up a reverse proxy (optional but recommended)

Cloudflare:

Point your DNS A record to your Unraid IP
Enable Always Use HTTPS in Cloudflare dashboard (SSL/TLS → Edge Certificates)
Keep COOKIE_SECURE=false — Cloudflare terminates TLS before Flask sees the request
CF-IPCountry header is forwarded automatically — no extra configuration needed for geographic analytics

Nginx Proxy Manager:

Add a proxy host: your domain → unraid-lan-ip:5000
Issue a Let's Encrypt certificate on the SSL tab
Keep COOKIE_SECURE=false — same reason as Cloudflare
Country detection falls back to ip-api.com (free, no key required, <45 req/min)

Step 5 — Verify

docker inspect --format='{{.State.Health.Status}}' qrknit
# healthy

curl https://yourdomain.com/api/health
# {"status":"ok"}

Updating

Your data lives in the Docker volume and is preserved across updates.

Docker / Docker Compose:

cd /path/to/qrknit-src
git pull
docker build -t qrknit:latest .
docker stop qrknit && docker rm qrknit
# Re-run the same docker run command from installation

Unraid:

cd /mnt/user/appdata/qrknit-src
git pull
docker build -t qrknit:latest .

Then click Force Update on the container in the Docker tab.

Sessions survive restarts as long as SECRET_KEY stays the same. Changing SECRET_KEY invalidates all active sessions — users will need to log in again.

Environment Variables

Variable	Default	Description
`BASE_URL`	`http://localhost:5000`	Public URL of your instance — used in short links and QR codes
`APP_NAME`	`My.Links`	Display name in the header, hero, login modal, and page title. Names with a dot are split and styled automatically.
`SECRET_KEY`	(required)	Signs session cookies — use a long random string
`ADMIN_PASSWORD`	(required)	Admin account password — upserted on every startup
`ADMIN_USERNAME`	`admin`	Admin account username
`PORT`	`5000`	Port Gunicorn listens on
`DEBUG`	`false`	Flask debug mode — keep `false` in production
`COOKIE_SECURE`	`false`	Set `true` only if Flask receives HTTPS directly (not behind a proxy)
`DB_PATH`	`/app/data/qrknit.db`	SQLite file path — leave as-is when using a Docker volume
