Creating Smaller Docker Images

This technical article discusses the common problem of large Docker image sizes. It explains how using base images like Debian and installing build tools adds significant bulk, and why deleting files in later RUN commands doesn't reduce size due to Docker's layer system. The article provides practical solutions, such as combining commands into a single RUN statement and using multi-stage builds, to create minimal production images. It uses building a Redis server as a concrete example.
