Roy Arsan 6234fa8f14 Add Claude Gateway on GCP example deployment assets
Reference artifacts accompanying the Gateway-on-GCP walkthrough
(https://code.claude.com/docs/en/claude-apps-gateway-on-gcp), including
its Terraform reference section:

- setup.sh: scripts the walkthrough end to end via gcloud (APIs, service
  account, image build/push, private-IP Cloud SQL, secrets, Cloud Run)
- Dockerfile: runtime image for the gateway; setup.sh downloads the
  public release binary and verifies it against the release manifest
- gateway.yaml.example: config template (Vertex upstream, Google
  Workspace IdP)
- terraform/: module provisioning the same architecture (Cloud Run track)

Provided as a working example to adapt, not a supported production
deployment.

# Public access at the Cloud Run IAM layer (the gateway runs its own OIDC):
# Preferred — disable the invoker check: no allUsers binding, works under Domain
# Restricted Sharing. Needs google provider >= 6.8 and the feature enabled for your org:
# invoker_iam_disabled = true
# Fallback — grant allUsers (fine on a normal org; Domain Restricted Sharing rejects it,
# so there prefer invoker_iam_disabled, or use a DRS exception / GKE):
allow_unauthenticated = true
# Network reachability — a separate axis from the IAM choice above. Default is internal-only:
# no public URL (Claude Code's /login only accepts gateway hosts on private addresses, so
# public ingress cannot serve clients); corp on-prem reaches run.app via a PSC endpoint +
# private run.app DNS — see README "Private access" for the prerequisites. The only
# alternative to the internal-only default:
# ingress = "INGRESS_TRAFFIC_INTERNAL_LOAD_BALANCER" # only if you front it with your OWN internal ALB (custom hostname/cert; not provisioned here)
# Google OAuth client secret: REQUIRED — uncomment and set it (Terraform creates the
# secret version; the Cloud Run service mounts `latest`, so without a version the
# deploy fails). Leave empty only if you add the secret version out-of-band.
