Docker Image Optimization: From 1GB to 50MB
The Hidden Costs of Oversized Images Many teams overlook image size during the early stages of containerization. A Spring Boot image often weighs 800MB–1.2GB, and even a Go application image can easily exceed 700MB. The problems caused by oversized images go far beyond “wasting a little disk space”: Slow pulls and deployment latency: In CI/CD pipelines or elastic scaling scenarios, nodes must pull the image before starting the container. A 1GB image takes over 80 seconds to download on a 100 Mbps internal network, while a 50MB image takes just 4 seconds....
