Deploy a 3-node OC-managed Incus cluster with OVN overlay networking
and an HA nginx workload behind an OVN load balancer. Key discoveries:
- OC needs_update blocker: OC tracks update delivery through its pipeline,
not version comparison. Nodes deployed from the latest ISO are stuck at
needs_update=true. Fix: generate ISO from older channel (--channel
old-stable), let OC push the real update after registration.
- ISO upload skip bug: incusos-proxmox silently reused stale ISOs with the
same filename. Fixed: --iso now replaces existing same-named ISOs.
- Empty app-seed-config ({}): avoids "Certificate already in trust store"
Terraform error when cert is already injected via SEED_DATA.
Files changed:
- notes/operations-center-guide.md: full rewrite with real captured output
- CLAUDE.md: needs_update findings, ISO fix, OVN LB behavior
- incusos/examples/lab-oc-deploy.yaml: static IP for VLAN 69
- incusos/examples/lab-oc-nodes.yaml: static IPs + disk sizing
- incusos/incusos-proxmox: fix stale ISO reuse when --iso provided

incu-contrib
Peripheral tools, snippets, and scripts for working with Incus, IncusOS, and the broader ecosystem.
Primarily aimed at home lab environments but useful in production as well.
Contents
incusos/
Scripts for building IncusOS installation media and seed configurations:
-
incusos-iso-- Build customized IncusOS ISO/IMG images using the official flasher-tool. Supports both architectures (x86_64, aarch64), multiple applications (Incus, Operations Center), automatic client certificate injection, and batch generation. -
incusos-seed-- Generate IncusOS seed archives (tar or FAT image) for installation customization. Covers all seed file types: install, applications, Incus preseed, Operations Center, network, and update configuration. -
incusos-proxmox-- Declarative IncusOS deployment on Proxmox VE. Define VMs in YAML, and the script handles seed generation, ISO upload, VM creation with correct settings (UEFI, TPM 2.0, VirtIO-SCSI), and automated installation.
See incusos/README.md for full documentation.

Research notes and reference material:
incus-version-compatibility.md-- Incus package versions across platforms (macOS, Debian/Ubuntu, Arch), install instructions, and certificate management notes.iso-download-methods.md-- Original research on ISO download/customization approaches.clustering-guide.md-- Detailed Incus clustering walkthrough (manual cluster formation via remotes).operations-center-guide.md-- Operations Center provisioning, cluster management, and tested limitations.migration-guide.md-- Migration paths into Incus from Proxmox, UTM, VMware Fusion, and Docker.utm-support.md-- Design document for future UTM support on macOS.
Quick Start
# Install the flasher-tool (requires Go 1.22+)
go install github.com/lxc/incus-os/incus-osd/cmd/flasher-tool@latest
# Build a default IncusOS ISO with your client cert injected
./incusos/incusos-iso
# Build for a specific architecture and application
./incusos/incusos-iso --arch aarch64 --app operations-center --defaults
# Generate all common ISO variants at once
./incusos/incusos-iso --batch
# Generate a standalone seed archive
./incusos/incusos-seed --app incus --defaults --output my-seed.tar
# Generate a SEED_DATA FAT image for external boot media
./incusos/incusos-seed --format fat --app incus --defaults --output seed.img
Requirements
- Go 1.22+ -- for installing the flasher-tool
- curl -- for downloading images from the CDN
- tar, gzip -- for seed archive creation and image decompression
- Incus client (recommended) -- for automatic client certificate detection. Works with any version; certificates are read directly from disk. See version compatibility notes for install instructions per platform (macOS, Debian/Ubuntu, Arch).
- mtools (optional) -- for creating FAT seed images
