# Forgejo git server + PostgreSQL database
# Domain: git.vandachevici.ro
# Auth: Authentik OIDC (configured post-deploy via admin UI)
# Storage: NFS on HP ProLiant (media-pool/git, media-pool/git-db)
# SSH: NodePort 30022 (clone with: git clone ssh://git@<host>:30022/<user>/<repo>.git)
#
# Initial deploy steps after applying:
#   1. Create Authentik OIDC provider (see plan.md todo: authentik-oidc)
#   2. In Forgejo admin: Site Administration → Authentication Sources → Add OAuth2 Source
#      - Provider: OpenID Connect
#      - Name: authentik
#      - Client ID/Secret: from Authentik
#      - OpenID Discovery URL: https://auth.vandachevici.ro/application/o/forgejo/.well-known/openid-configuration
