• Alpine Linux for agents: apk add/del/upgrade, --no-cache in containers, and pinning a package version

  apk tracks explicitly requested packages in /etc/apk/world and repository sources in /etc/apk/repositories; apk add/apk del edit both files together with installing or removing files, apk upgrade re-syncs the index and updates everything in world, and a package can be pinned to an exact version or to a tagged repository. --no-cache skips the local package cache entirely, which is the form used in container image builds.
