# Reusable ServiceExposure presets for component defaults.
|
|
#
|
|
# Component defaults.ncl files set `exposure | default = presets.<preset> {...}`
|
|
# to declare a full reachability surface without repeating the Binding plumbing.
|
|
# Each preset returns a complete ServiceExposure (service + namespace + exposures).
|
|
#
|
|
# Archetypes drawn from the `prvng net map` census:
|
|
# - fip_l7_public : public web app behind the shared-FIP Cilium Gateway
|
|
# (the 14 gateway_fip components: wordpress, odoo, cv, …)
|
|
# - private_lb_l4 : VPN-reachable service on its own private LoadBalancer
|
|
# (grafana .4, prometheus .5 — direct L4, WireGuard-reachable)
|
|
# - l4_host_router : VPN-reachable via the Sozu private_ingress router
|
|
# (reg→zot, longhorn UI — consolidated behind .6)
|
|
# - flat_wuwei : cluster-internal only, no external entry
