# Workload cluster lab1 (phase-1 Step 3). Generated 2026-09-27 with clusterctl v1.12.11:

# PROXMOX_SOURCENODE=pv1-1 TEMPLATE_VMID=101 ALLOWED_NODES="[pv1-1]" \

# CONTROL_PLANE_ENDPOINT_IP=192.168.4.30 NODE_IP_RANGES="[192.168.4.31-192.168.4.39]" \

# clusterctl generate cluster lab1 --infrastructure proxmox:v0.9.1 --kubernetes-version v1.35.9 \
|
||
# --control-plane-machine-count 1 --worker-machine-count 1 --target-namespace default
|
||
#
|
||
# Hand edits (docs/phase-1-proxmox-capi.md Step 3):
|
||
# 1. pod CIDR 192.168.0.0/16 -> 10.244.0.0/16 (overlaps the lab LAN)
|
||
# 2. kube-vip v0.7.1 -> v1.2.4 (kube-vip-prepare.sh kept)
|
||
# 3. `format: qcow2` removed from both ProxmoxMachineTemplates (local-lvm is LVM-thin, raw only)
|
||
# 4. `vlan: 4` on net0 of both ProxmoxMachineTemplates
|
||
# 5. lab1-worker: 1 socket x 4 cores, 4096 MiB (owner's choice; runbook said 8192)
|
||
# 6. MachineDeployment lab1-workers: `replicas` removed (the autoscaler owns it)
|
||
# 7. MachineDeployment lab1-workers: autoscaler min/max + capacity annotations (runbook Step 5)
