Ansible Roles hailo and hailo_ollama 0.2.0

A day after the initial release , both Hailo roles get version 0.2.0 - with two notable jumps: selectable package sources (Raspberry Pi repository or Hailo vendor) and a full web-UI delivery built around Open WebUI and an optional Caddy TLS frontend.

• head1328.hailo - driver and runtime for the Hailo NPU
• head1328.hailo_ollama - Hailo Ollama LLM server with Open WebUI and Caddy reverse proxy

head1328.hailo

#

The base role installs the Hailo driver and runtime. Supported hardware:

New in 0.2.0:

• Selectable source: hailo_source: raspberry (Raspberry Pi OS apt repo) or hailo_source: vendor (packages from dev-public.hailo.ai )
• hailo_vendor_version and hailo_vendor_base_url variables for pinning vendor packages
• Automatic cleanup of conflicting packages when switching between raspberry and vendor
• More robust apt state handling across source switches
• Dedicated molecule scenario for the vendor variant, including idempotence tests

head1328.hailo_ollama

#

Builds on top of the driver role and adds an LLM server for the Hailo-10H NPU. Containers run rootless via Podman Quadlets.

New in 0.2.0:

• Selectable source: Hailo GenAI Model Zoo from Raspberry Pi OS or directly from the Hailo vendor
• Open WebUI as the chat frontend (enabled by default, pinned to 0.8)
• Optional Caddy reverse proxy with TLS
• iptables PREROUTING redirect for privileged ports, persisted across reboots via iptables-persistent
• Caddy workarounds for Open WebUI 0.8 (/config stub, /api/*/0 path rewrite)
• Open WebUI title generation and follow-up suggestions disabled by default (NPU limitation: one request at a time)
• OLLAMA_HOST env var in the systemd unit for hailo-ollama 5.3.0 compatibility
• Instructions for importing the Caddy root CA into the browser

What It’s For

#

Anyone who wants to run a Raspberry Pi 5 with AI HAT+ 2 as a small local LLM server - no GPU, no cloud account required. Combined with head1328.ivly you get a fully self-hosted back-office environment with LLM support.
