# APK
|
|
APK is a package manager used on [Alpine Linux](../../../linux/Alpine%20Linux.md).
|
|
|
|
Software packages for [Alpine Linux](../../../linux/Alpine%20Linux.md) are digitally signed [tar.gz](../../cli/compression/tar.md) archives containing programs, configuration files, and dependency metadata. They have the extension `.apk`, and are often called "a-packs".
|
|
|
|
The packages are stored in one or more repositories. A repository is simply a directory with a collection of `*.apk` files. The directory must include a special index file, named `APKINDEX.tar.gz` to be considered a repository.
|
|
|
|
The apk utility can install packages from multiple repositories. The list of repositories to check is stored in `/etc/apk/repositories`, one repository per line.
|
|
|
