Resolves authentik deployment issues by implementing proper Podman Quadlet
configuration and fixing networking for external access through Caddy.
Core Fixes:
• Add missing [Install] sections to container Quadlet files for systemd service generation
• Fix pod references from 'systemd-authentik' to 'authentik.pod' for proper Quadlet linking
• Remove problematic --userns=host to use proper rootless user namespaces
• Configure subuid/subgid ranges for authentik user (200000:65536)
• Update networking to bind 0.0.0.0:9000 only (remove unnecessary HTTPS port 9443)
• Add AUTHENTIK_LISTEN__HTTP=0.0.0.0:9000 environment configuration
• Fix Caddy reverse proxy to use HTTP backend instead of HTTPS
Infrastructure Updates:
• Enhance PostgreSQL role with Unix socket configuration and user management
• Improve Valkey role with proper systemd integration and socket permissions
• Add comprehensive service integration documentation
• Update deployment playbooks with backup and restore capabilities
Security Improvements:
• Secure network isolation with Caddy SSL termination
• Reduced attack surface by removing direct HTTPS container exposure
• Proper rootless container configuration with user namespace mapping
Result: authentik now fully operational with external HTTPS access via auth.jnss.me
All systemd services (authentik-pod, authentik-server, authentik-worker) running correctly.
- Provides PostgreSQL server as shared database infrastructure
- Follows KISS principle with only essential configuration (11 variables vs 45 originally)
- Implements maximum security with Unix socket-only superuser access
- Uses scram-sha-256 authentication for application users
- Includes SystemD security hardening
- Applications manage their own databases/users via this infrastructure
- Production-ready with data checksums and localhost-only access
