# When false, this role will not enable or rewrite UFW. Use that for hosts
|
|
# whose live packet filter is not UFW (CoulombCore: iptables INPUT DROP with
|
|
# a Plesk-era accept list). Enabling UFW there is an availability decision,
|
|
# not a side effect of an unrelated converge.

# Source addresses permitted to reach the k3s API (6443/tcp).
|
|
#
|
|
# WHY THIS EXISTS
|
|
# ---------------
|
|
# The k3s API was originally opened to Anywhere by this role, and the source
|
|
# restriction was later added by hand on the live host. That left the declared
|
|
# config WEAKER than reality: re-running this role would have removed the
|
|
# restriction and exposed the Kubernetes API to the internet. Found 2026-08-11.
|
|
#
|
|
# Operator addresses rotate (dynamic ISP leases). An allowlist is a treadmill:
|
|
# each rotation is either an outage or a stale grant to whoever the ISP
|
|
# reassigns the address to. RAIL-HO-WP-0009-T04 therefore keeps this list
|
|
# empty. Reach the API over the ops-bridge SSH tunnel
|
|
# (`k3s-api-railiance01`, local port 16444; `k3s-api-coulombcore`, 16443).
|
|
# See docs/adr/ADR-005-k3s-api-tunnel-only.md.
|
|
#
|
|
# Deliberately empty by default. A host that sets no sources gets NO public
|
|
# access to 6443 — which is the safe failure. SSH (22) is unaffected, so a host
|
|
# converged with an empty list is always recoverable.
