Root Cause

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.

Workarounds

  1. 75% success 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.

Dead Ends

Common approaches that don't work:

  1. 95% fail

    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% fail

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