proxmox-infrastructure

name	proxmox-infrastructure
description	Manage the Matrix/Virgo-Core Proxmox VE cluster (nodes Foxtrot, Golf, Hotel - MINISFORUM MS-A2 with AMD Ryzen 9 9955HX). Covers VM provisioning, VLAN networking, CEPH storage, and automation via Python (proxmoxer), Ansible (community.general.proxmox), and Terraform (Telmate/proxmox).
when_to_use	Use when cloning VM templates, checking CEPH storage health, configuring VLAN networking for Proxmox VMs, creating cloud-init templates, checking node status (Foxtrot, Golf, Hotel), deploying VMs with Terraform, configuring MTU 9000 for CEPH networks, troubleshooting VM deployment, using Ansible proxmox modules, or validating template configuration via the Proxmox API.

Proxmox Infrastructure: Matrix/Virgo-Core Cluster

Manage 3-node Proxmox VE cluster with CEPH storage, VLAN networking, and cloud-init automation.

Available Tools

Python Scripts (uv-based)

• validate_template.py - Validate template health via Proxmox API
• cluster_status.py - Cluster health metrics and node status
• check_ceph_health.py - CEPH storage pool health monitoring
• check_cluster_health.py - Comprehensive cluster diagnostics

All scripts support --help for usage. Run with: uv run tools/<script>.py

Automation Examples

• Ansible playbooks - Template creation, VLAN bridging setup
• Terraform modules - VM cloning, multi-node deployments with dual NICs

See examples/ and workflows/ for working configurations.

Core Capabilities

Template Management:

• Ubuntu/Debian cloud-init templates with virtio-scsi
• Serial console configuration for cloud images
• Proper boot order and cloud-init CD-ROM (ide2)

Network Infrastructure:

• vmbr0: Management (VLAN 9 for Corosync)
• vmbr1: CEPH Public (192.168.5.0/24, MTU 9000)
• vmbr2: CEPH Private (192.168.7.0/24, MTU 9000)
• VLAN-aware bridging (supports VLANs 2-4094)
• 802.3ad LACP bonding

CEPH Storage:

• Multi-OSD configuration (2× 4TB NVMe per node)
• MTU 9000 for storage networks
• Public/private network separation
• Health monitoring and diagnostics

API Automation:

• Python via proxmoxer library
• Ansible via community.general.proxmox_* modules
• Terraform via Telmate/proxmox provider

Cluster Architecture (Matrix)

Hardware: 3× MINISFORUM MS-A2

• AMD Ryzen 9 9955HX (16C/32T)
• 64GB DDR5 @ 5600 MT/s
• 3× NVMe: 1× 1TB boot, 2× 4TB CEPH OSDs
• 4× NICs: 2× 10GbE SFP+, 2× 2.5GbE

Nodes: Foxtrot, Golf, Hotel

Quick Examples

Clone template to VM:

qm clone 9000 101 --name web-01
qm set 101 --ipconfig0 ip=192.168.3.100/24,gw=192.168.3.1
qm set 101 --net0 virtio,bridge=vmbr0,tag=30
qm start 101

Check cluster health:

uv run tools/cluster_status.py
uv run tools/check_ceph_health.py
