## Build & Configuration
### Prerequisites
None
No specific prerequisites for this stack.
### Volume Setup
```bash
mkdir -p /DockerVol/Authentik/Postgres:/var/lib/postgresql/data
chown -R 1964:1964 Authentik/
mkdir -p /DockerVol/Authentik
chown -R authentik:authentik /DockerVol/Authentik
```
### Environment Variables
```bash
AUTHENTIK_REDIS__HOST=redis
AUTHENTIK_POSTGRESQL__HOST=postgresql
AUTHENTIK_POSTGRESQL__USER=authentik
AUTHENTIK_POSTGRESQL__NAME=authentik
# generate: openssl rand -hex 32
AUTHENTIK_SECRET_KEY=g8JIvopgkcpIeRUKgfT5KwHFUwGNBFobwhHMHx08wPTJTtAlmqllAwmr6u4jk+ng8O1gbV/gwZnYylMn

### First Run
Post-deploy steps not applicable for this service.
Run `./deploy.sh` to complete the initial setup.

## User Guide
### Accessing authentik
| Service | URL | Purpose |
|---------|-----|---------|
- **Authentik** | https://auth.netgrimoire.com | Management |
- **Authentik** | https://auth.netgrimoire.com | Account Manager |
### Primary Use Cases
Access and manage user accounts, configure authentication settings, and monitor the system for security.
Use authentik for user identity management, access control, and auditing.
### NetGrimoire Integrations
This service connects to the Caddy reverse proxy (caddy: auth.netgrimoire.com) for URL forwarding and Uptime Kuma (kuma.* labels) for monitoring.
Authentik integrates with other NetGrimoire services via environment variables and labels. For example, it uses the `AUTHENTIK_POSTGRESQL__HOST` variable to connect to the PostgreSQL database.
---
## Operations
### Monitoring
[kuma monitors from kuma.* labels]
```bash
docker stack services authentik
docker service logs -f authentik
```
### Backups
Critical data is stored in /DockerVol/Authentik/Postgres, and the PostgreSQL database should be regularly backed up. Non-critical data is stored in /DockerVol/Authentik/media.
Critical: backup critical data in `/DockerVol/Authentik/media` and `/DockerVol/Authentik/custom-templates`.
### Restore
```bash
cd services/swarm/stack/authentik
./deploy.sh
```
Reconstructable: backup `/DockerVol/Authentik/certs` if necessary.

## Common Failures
| Symptom | Cause | Fix |
|---------|-------|-----|
- Service not responding | Postgres or Redis down | Check logs, restart the service |
- Authentication issues | Missing credentials or invalid credentials | Ensure correct credentials are used |
| Service not available | Network issue | Check Caddy logs for errors. |
| Database corruption | Data loss | Run `docker exec -it authentik pg_resetdb` to reset the database. |
| Redis down | Configuration issue | Check `docker service logs redis` for errors and adjust configuration as needed. |
