GCP Gateway Upload Size Limit

Key Fact

GKE Gateway (Gateway API HTTPRoute) has no native body-size filter. HTTPRoute Filter types: RequestHeaderModifier, ResponseHeaderModifier, RequestRedirect, ResponseRedirect, URLRewrite, RequestMirror. No client_max_body_size equivalent.

Enforcement Layers (correct to wrong)

  1. IIP nginx .so — client_max_body_size (correct primary enforcement)
  2. Kong Gateway — request-size-limiting plugin (if Kong is upstream)
  3. Application/pod — application code or nginx sidecar
  4. ~~GKE Gateway~~ — not possible, Gateway API does not support it
  5. ~~Cloud Armor~~ — WAF rules, not precise upload control

Layered Strategy

Set a loose upper bound at IIP (e.g., 500M) as a security guard, then precise business limits at Kong/Runtime (e.g., 10M per team/service).
