View show details

In episode 81 of The Software Engineering Podcast, Lucas and Luna explore how a senior DevOps engineer at a mid-sized SaaS company shrunk Docker images from 1.8 GB to under 90 MB — cutting deployment times by 70 percent and saving $12,000 a year in storage costs. They walk through the specific techniques used: multi-stage builds, Alpine base images, distroless runtimes, and layer optimisation. The conversation also touches on how these principles apply beyond containers, from CI pipelines to serverless deployments. If you've ever wondered why your Docker images are bloated or how to shrink them without breaking anything, this episode gives you a concrete playbook. #Docker #ContainerOptimisation #DevOps #MultiStageBuilds #AlpineLinux #DistrolessImages #LayerCaching #CI_CD #CloudCostOptimisation #SoftwareEngineering #Technology #FexingoBusiness #BusinessPodcast #EngineeringBestPractices #SaaSInfrastructure #DockerImageSize #SeniorDevOps #DeploymentSpeed Keep every episode free: buymeacoffee.com/fexingo
