# =============================================================================
# Alertmanager (TASK-0135, phase-15) — Deployment + Service, ns `monitoring`.
#
# Config is generated into `alertmanager-config` by kustomization.yaml FROM
# infrastructure/observability/alertmanager/alertmanager.yaml (single source
# of truth). SMTP: alertmanager reads auth ONLY from its config file (no env
# substitution) — if the relay requires credentials, add
# smtp_auth_username / smtp_auth_password to the source file (or render the
# ConfigMap from a SealedSecret in the pipeline); the default assumption is
# an open VPC relay. Without SMTP the webhook receiver still delivers (the
# dogfood path).
# Image pinned: prom/alertmanager:v0.27.0.
