# Alpine Repositories

Alpine Package Keeper (APK) is the package manager for Alpine Linux. APK installs and manages `.apk` packages used by Alpine systems and container images.

Nexus Repository supports Alpine repositories in Pro and Community Editions. You can use Alpine repositories to proxy upstream Alpine mirrors, host internal packages and expose multiple Alpine repositories through a single group endpoint.
