Why this Configuration?
- True Data Sovereignty: 100% GDPR-compliant on-premises deployment. You own your configuration and data without vendor lock-in.
- Hardware Agnostic: Optimized and verified across low-power ARM64 SBCs (Raspberry Pi 5) and x86_64 hypervisors (Proxmox VE LXC & VM).
- Engine Freedom: Tested and supported under standard Docker Engine and unprivileged rootless Podman.
- Platform Verification: Tested on Proxmox LXC: docker (v2.11.4, 2026-09-14), podman (v2.11.4, 2026-09-14); Proxmox VM: docker (v2.11.4, 2026-09-14), podman (v2.11.4, 2026-09-14).
