# Wave 7 — api-gw, the cluster's API gateway (namespace `api`).
#
# Replaces Kong OSS 3.4.1, removed 2026-08-19. Kong existed to route
# `api.riotpiao.com`, but Kong OSS cannot dispatch on a request body, so the
# LLM surface had to be expressed as one path per model
# (`/v1/reasoning/chat/completions`, `/v1/ornith/...`, `/v1/qwen/...`) with a
# `request-transformer` plugin forcing the body's `model` field on each. The Go
# gateway reads the body and picks the upstream, so a single canonical
# `POST /v1/chat/completions` covers every model. See
# docs/adr/ADR-0001-retire-kong-for-go-gateway.md in the frontend repo.
#
# UPDATED 2026-08-22: Tracks main branch of homelab-frontend (auto-syncs on each push).
# Image built on every main commit with tag <commit-sha>.
# ArgoCD auto-pulls the latest image (live reconciliation ~3min).
#
# Two sources:
#   1. rock/homelab-frontend on the in-cluster Forgejo (prod branch) — the gateway's own
#      kustomization (Deployment, Service, ConfigMap, RBAC, NetworkPolicy). It
#      sets `namespace: api` itself, so no transformer is needed here. The
#      Forgejo host must stay listed in the `homelab` AppProject sourceRepos or
#      this Application is rejected with "is not permitted in project".
#   2. k8s/apps/api in this repo — the nginx edge Ingress for
#      api.riotpiao.com, inherited from the retired `kong` Application. It
#      cannot move to k8s/bootstrap/ingress/ingress.yaml because that syncs in
#      wave 1, before namespace `api` exists.
#
# No resources-finalizer: deleting this Application leaves the workload running
# rather than cascading the delete.
