# signage module update — a bare Debian VM (scaffold).
|
||
|
|
#
|
||
|
|
# The VM is created by the cluster:vm provider (Debian 13 cloud image) and
|
||
|
|
# OS-prepped by templates:debian. This module currently only confirms the VM is
|
||
|
|
# up and records a version marker — the signage software will be layered on in a
|
||
|
|
# later pass. install == update for this module.
|
||
|
|
#
|
||
|
|
# Runs on tappaas-cicd: resolves the VM's IP via the Proxmox guest agent, then
|
||
|
|
# drives the VM over SSH. Idempotent.
|
||
|
|
#
|
||
|
|
# Usage: update.sh <module-name>
