Upgrading to Edge

An upgrade of Alpine Linux from a stable version to the rolling development version, edge can be done in a few simple steps.

Warning: Edge is under constant development so be careful using it in production. It can break your system.

1. Add the edge repository to /etc/apk/repositories:

   echo http://dl-3.alpinelinux.org/alpine/edge/packages/main >> /etc/apk/repositories

   or just edit the file in-place (replace v2.2 with your release)

   sed -i -e 's/v2.2/edge/g' /etc/apk/repositories

2. Upgrade all packages in one shot

   apk upgrade -a -U

3. Check your current release

   cat /etc/alpine-release

   You will see the build date attached to the release.
