A Patch Deployment that Targets Hosts and Reboots When Needed
An instance filter that matches nothing patches nothing - the deployment runs on schedule, reports success and touches no host - and reboot_config NEVER installs the kernel and keeps running the old one. Refuses an empty filter, makes all-instances a stated choice because it includes the databases, reboots when the packages need it, and caps the share of a zone patched at once.

Documentation
gcp-os-config-patch
A patch deployment that targets something, runs on a schedule, and reboots
when a patch needs it. Works with Terraform and OpenTofu (>= 1.6),
google provider >= 6.0, < 7.0.
An instance filter that matches nothing patches nothing - the
deployment runs on schedule, reports success, and touches no host. A filter
with no selector is refused; all = true needs accept_all_instances
because it includes the database servers.
reboot_config = "NEVER" installs the kernel and keeps running the old
one. DEFAULT here; NEVER needs accept_no_reboot.
The disruption budget is the blast radius. 25% of a zone at a time by
default; 100% needs accept_whole_zone_at_once.
Verification
Static validation runs tofu fmt, init, validate, tflint and checkov.
This module has not yet had a live test, so it is published as statically
validated with its live test pending and does not carry the live-tested mark.
