DevOps Daily with Fexingo · 2026-07-11 · 8 min
Episode 105 of DevOps Daily dives into a surprising CI bottleneck: Docker image layer caching that backfires. Lucas and Luna examine how layer reuse assumptions break down in environments with dynamic dependency trees, leading to cache-miss avalanches and pipeline slowdowns. They walk through a real case study from a mid-size e-commerce team that saw CI times balloon from 8 to 22 minutes after adopting multi-stage builds, then cut them back to 11 minutes by switching to a cache-unfriendly base image strategy. The episode covers cache hit ratios, layer invalidation patterns, and why buildkit's - cache-from isn't always the answer. No fluff, just a sharp technical breakdown. #Docker #ImageLayerCaching #CI #Buildkit #MultiStageBuilds #CacheMiss #PipelinePerformance #DevOps #SoftwareOperations #Technology #FexingoBusiness #BusinessPodcast #LucasAndLuna #DependencyManagement #CacheHitRatio #LayerInvalidation #BaseImageStrategy #BuildOptimization Keep every episode free: buymeacoffee.com/fexingo
