Stand up the git.unkin.net forge on k8s to replace the Puppet VM. Deployed HA-shaped to match what the VM already runs (multi-replica on shared storage + external DB/cache), so this is genuine multi-replica HA rather than single-replica failover. Serves a temporary git2.k8s.syd1.au.unkin.net host; the git.unkin.net cutover is staged in docs/gitea-migration.md. - add apps/base/gitea: namespace, CNPG gitea-postgres (2 instances, S3 backup bucket cnpg-gitea, nightly 04:00/30d), pgbouncer pooler, standalone Valkey (session/cache/queue, AOF), VaultAuth + VaultStaticSecrets, Gateway + HTTPRoute - add apps/overlays/au-syd1/gitea: official Gitea chart 12.6.0 (app 1.26.2, rootless, 2 replicas) via helm-through-kustomize; RWX CephFS repo storage, external CNPG + Valkey, Actions disabled, container registry disabled (moved to artifactapi), Authentik OIDC with auto-register/account-linking; SSH via LoadBalancer VIP 198.18.200.10:2222 - register gitea in the platform ApplicationSet + AppProject - add docs/gitea-migration.md staged cutover plan (VM Postgres->CNPG dump/restore, DNS in main.unkin.net zone, consumer checklist, rollback) Depends on: terraform-authentik gitea OIDC app, and terraform-artifactapi ^gitea/ dockerhub allowlist (both separate PRs). One-time Vault seeds are listed in the migration doc. Reviewed-on: #309 Co-authored-by: Ben Vincent <ben@unkin.net> Co-committed-by: Ben Vincent <ben@unkin.net>
