description: >-
  Carvel operates no endpoint, so it imposes no rate limit and returns no rate-limit header —
  limit_count is 0 because there is nothing to limit, not because limits are undocumented. This
  file replaces a 2026-05-04 bulk-sweep scaffold that had invented per-key quotas and
  X-RateLimit-* headers for an API that does not exist. The throttling a Carvel user actually
  meets belongs to third parties, and is recorded below as such.

    note: >-
      Docker Hub, GHCR, ECR and Harbor each enforce their own pull/push limits. imgpkg copy of a
      large bundle is the operation most likely to hit them; the docs cover proxy configuration
      and resumable tar copies, not rate limits.

    applies_to: [kapp, kctrl, kapp-controller, secretgen-controller]
    note: >-
      Client-side QPS/burst and server-side API Priority and Fairness are the cluster's settings.
      kapp exposes --apply-concurrency (default 5) and --apply-check-interval (default 1s), which
      shape how hard it drives the apiserver.
