BuildKit Registry Authentication Failures

configurationUpdated Feb 23, 2026

CrewAI crew builds fail when BuildKit cannot authenticate to container registries, causing silent build failures and preventing crew deployment updates. Network connectivity issues or missing registry secrets compound the problem.

How to detect:

Monitor BuildKit pod status and logs for registry authentication errors. Track crew build failure rates and correlate with registry authentication events. Alert when builds fail with 'unauthorized' or 'authentication required' errors. Monitor BuildKit pod restarts and resource exhaustion.

Recommended action:

Verify docker-registry secret exists and is correctly configured in Kubernetes. Configure insecure registry settings for internal registries if needed. Increase BuildKit resource limits (CPU/memory) if builds are failing due to resource constraints. Monitor BuildKit network connectivity to registry endpoints. Implement registry health checks in deployment pipeline.
