From 6d193158d5eee564f18e2e538915b11c516459ef Mon Sep 17 00:00:00 2001 From: Maarten Date: Tue, 24 Feb 2026 22:19:03 +0100 Subject: [PATCH] Rewrite production lab guide for OC-managed provisioning MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Rewrites sections 0-6 from scratch with OC-managed clustering (tokens, OC ISOs, auto-registration) replacing manual cluster formation. Updates sections 7-15 with correct naming (oc-node-* instead of lab-node-*), fixes device override bug, and adds sequential launch guidance. Key changes: - Architecture: new VMID scheme (920/400-402), IP scheme (.120/.140-142) - Node-01 disk increased to 250 GiB for Aether golden image - OC provisioning flow: token → older-channel ISO → auto-update - Fixed root device config: device override instead of device set - Added image download timing notes (sequential, not concurrent) - Updated OC Dashboard section for OC-managed deployment - Updated node replacement procedure with correct VMIDs/IPs - Updated cleanup to use --cleanup-all --deep --yes Full lab validated from scratch: deploy, cluster, OVN, workloads, isolation, peering, load balancing, live migration, evacuation/restore.

Manual clustering via `incus` CLI is proven -reliable. OC still provides value as a monitoring dashboard. +**Why OC-managed clustering?** OC `provisioning cluster add` is the +production path for Incus deployments. It handles cluster formation, +update management, and inventory centrally. The deploy scripts +(`deploy-haproxy`, `deploy-awx`, `deploy-observability`) are built +for the `oc-node-*` naming and IP scheme. -**Why OVN?** Bridge networks are node-local — instances on different nodes -cannot communicate. OVN provides transparent cross-node L2 overlay with -sub-millisecond latency (~0.1-0.8ms), network isolation, ACLs, load -balancers, and network forwards. +**Why 20 GiB RAM per node?** Aether requires 8 GiB. AWX requires +4-8 GiB. Monitoring + HAProxy + backends need ~3 GiB total. +Leaves headroom for mixed workloads and live migration. -**Why VLAN 69?** Isolates lab traffic from the production LAN. All VMs share -VLAN 69 (subnet 192.168.100.0/22). The VLAN tag is set at the Proxmox VM -level — IncusOS and workloads are unaware of it. +**Why 250 GiB disk for node-01?** Aether's golden image is 200 GiB +virtual (qcow2). With ZFS thin provisioning only ~11 GiB is used +initially, but the pool needs 200 GiB allocatable space. + +**Why OVN?** Bridge networks are node-local — instances on different +nodes cannot communicate. OVN provides cross-node L2 overlay with +sub-ms latency, network isolation, ACLs, load balancers, and network +forwards — essential for HAProxy HA and distributed workloads. + +**Why VLAN 69?** Isolates lab traffic from the production LAN. All VMs +share VLAN 69 (subnet 192.168.100.0/22). The VLAN tag is set at the +Proxmox level — IncusOS and workloads are unaware of it. ### Cross-References -This guide brings together techniques from the deep-dive guides: +This guide integrates techniques from the deep-dive guides: -- [Clustering Guide](clustering-guide.md) — cluster formation, migration, lifecycle -- [Networking Guide](networking-guide.md) — OVN setup, ACLs, peering, LBs +- [Clustering Guide](clustering-guide.md) — manual cluster formation reference +- [Networking Guide](networking-guide.md) — OVN setup, ACLs, peering - [Operations Center Guide](operations-center-guide.md) — OC provisioning, CLI, web UI -- [Migration Guide](migration-guide.md) — importing VMs from other hypervisors +- [Aether Guide](aether-guide.md) — management platform deployment and API +- [HAProxy Guide](haproxy-guide.md) — HA load balancing with Aether +- [AWX Guide](awx-guide.md) — Ansible lifecycle automation +- [Observability Guide](observability-guide.md) — Prometheus, Grafana, Loki stack ## Section 1: Prerequisites @@ -108,9 +161,40 @@ curl --version | head -1 genisoimage --version 2>&1 | head -1 ``` -**Minimum versions**: Incus client 6.3+ (for `remote get-client-certificate` -fallback, though scripts read `~/.config/incus/client.crt` directly), -Operations Center v0.3.0+. +**Minimum versions**: Incus client 6.3+, Operations Center v0.3.0+. + +### Aether Browser Automation + +Several Aether features (HAProxy management, blueprint deployment) are +not in the JWT API — they use session-authenticated routes with CSRF +protection.
