DevOps Daily with Fexingo · 2026-07-11 · 7 min
Lucas and Luna dissect a specific CI/CD failure pattern: Docker image layer caching that actually degrades pipeline performance. Using a real-world example of a mid-stage startup whose builds went from 4 minutes to 22 minutes after adopting a naive cache strategy, they explain layer invalidation, cache-miss cascades, and the trade-off between cache reuse and build determinism. Lucas walks through why copying package.json separately from source code matters, and Luna challenges the assumption that more cache always means faster builds. They end by discussing when to bypass the cache entirely for critical security patches. No abstract theory - just a concrete debugging story any team running containerized pipelines will recognize. #Docker #CICD #ImageLayerCaching #BuildPerformance #CI/CD #DevOps #FexingoBusiness #BusinessPodcast #Technology #SoftwareEngineering #Containerization #PipelineOptimization #LayerInvalidation #CacheMiss #BuildTime #Dockerfile #PackageJson #SecurityPatches Keep every episode free: buymeacoffee.com/fexingo
