## Overview ## Overview
The authentik Stack provides a Docker-based Authentik server for NetGrimoire, managing user identities and authentication. The Authentik stack is a NetGrimoire service that provides identity and access management for users in our organization. It consists of a PostgreSQL database, Redis cache, and an Authentik server.

### Primary Use Cases ### Primary Use Cases
Use the Authentik server to manage user identities, authentication, and authorization in NetGrimoire. Use Authentik for managing user identities and access controls within NetGrimoire.
### NetGrimoire Integrations ### NetGrimoire Integrations
This service connects to other services in NetGrimoire via environment variables and labels, including Redis and PostgreSQL databases. This stack integrates with PostgreSQL, Redis, Caddy, and Kuma.

## Operations ## Operations
### Monitoring ### Monitoring
Use kuma monitors from kuma.* labels to monitor the Authentik server. [kuma monitors from kuma.* labels]
```bash ```bash
docker stack services authentik docker stack services authentik
docker service logs -f authentik
``` ```
### Backups ### Backups
Critical data is stored in /DockerVol/Authentik/postgres. Regular backups are recommended. Critical: `/DockerVol/Authentik/Postgres` and `Authentik/redis` must be backed up regularly. Reconstructable: all configuration files are version-controlled.
### Restore ### Restore
Restore from a backup by re-deploying the Authentik Stack using ./deploy.sh. ```bash
cd services/swarm/stack/authentik
./deploy.sh
```
