Root Cause

Docker Hub enforces rate limits on anonymous users (100 pulls per 6 hours) and authenticated free users (200 pulls per 6 hours); the CI/CD pipeline or developer machine exceeded this limit.

generic

中文

Docker Hub 对匿名用户（每 6 小时 100 次拉取）和经过身份验证的免费用户（每 6 小时 200 次拉取）实施速率限制；CI/CD 管道或开发机器超出了此限制。

中文步骤

  1. 使用 docker login 登录 Docker Hub，将免费账户的限制提高到每 6 小时 200 次拉取。
  2. 使用 Docker Hub 付费订阅（Pro/Team）获得无限拉取，或将镜像镜像到私有仓库（如 Amazon ECR 或 GitHub Container Registry）。

Dead Ends

Common approaches that don't work:

  1. 40% fail

    Works but is impractical for CI/CD pipelines that need immediate builds; also, the limit resets based on a rolling window, not a fixed time.

  2. 80% fail

    The rate limit applies per image pull, not per tag; changing tags does not bypass the limit.
