根因分析

Cloud Run 冷启动延迟超过了 60 秒的 HTTP 负载均衡器超时，原因是容器镜像过大或应用程序初始化缓慢。

English

Cloud Run cold start latency exceeded the 60-second HTTP load balancer timeout because the container image is large or the application initialization is slow.

解决方案

  1. Reduce container image size by using a slim base image (e.g., 'alpine' instead of 'ubuntu') and removing build dependencies. For Node.js apps, run 'npm prune --production' before building the image.
  2. Enable min-instances for Cloud Run to keep at least one instance warm: 'gcloud run services update SERVICE --min-instances=1'. This eliminates cold starts for most requests.

无效尝试

常见但无效的做法:

  1. 95% 失败

    Larger resources do not reduce cold start time; they only affect runtime performance. Cold start is dominated by image download and app startup.

  2. 80% 失败

    Startup CPU boost only helps during the startup probe period, not the initial HTTP request timeout. The 504 occurs before the probe even begins.
