This paper provides an in-depth examination of two approaches for managing package caches in Alpine Linux Dockerfiles: using the apk add --no-cache option versus manually executing rm /var/cache/apk/* commands. Through detailed technical analysis, practical code examples, and performance comparisons, it reveals how the --no-cache option works and its equivalence to updating indices followed by cache cleanup. From the perspectives of container optimization, build efficiency, and maintainability, the paper demonstrates the advantages of adopting --no-cache as a best practice, offering professional guidance for lightweight Docker image construction.

This article explores common issues when running composer install in Docker environments, particularly the problem of missing dependencies when using volume mounts.
