# Playbook: app/proxmox_info.yml
# Purpose: Query Proxmox API for VM/LXC info (status, node, name, vmid) and
#          optionally filter to just the guests defined in `app_projects`.
# Targets: localhost
# Tags: app, proxmox, info
#
# Usage examples:
# - Show only projectA guests: ansible-playbook -i inventories/production playbooks/app/proxmox_info.yml -e app_project=projectA
# - Show all VMs/CTs on the cluster: ansible-playbook -i inventories/production playbooks/app/proxmox_info.yml -e proxmox_info_all=true
# - Restrict to only LXC: -e proxmox_info_type=lxc
