# This script will create and fire up a standard debian buster lxc container on your Proxmox VE.
# On a Proxmox cluster, the script will create the container on the local node, where it's executed.
# The container ID will be automatically assigned by increasing (+1) the highest number of
# existing LXC containers in your environment. If the assigned ID is already taken by a VM
# or no containers exist yet, the script falls back to the ID 100.
