Setting up the build environment on HDD
An existing Alpine Linux installation running in System Disk mode i.e traditional or classic harddisk installation can be used as build environment. Alternates are to setup a clean Alpine Linux build environment in a chroot inside another system, or some form of virtualization. The host system may also be Alpine Linux, or may be something else.
Upgrade to edge
An upgrade of Alpine Linux from a stable version to the rolling development version edge basically requires the same steps as Upgrading to latest release.
The crucial difference is, that when editing the /etc/apk/repositories file, all referenced repository versions (such as v3.22
or latest-stable
) therein need to be pointing to edge
as follows.
Contents of /etc/apk/repositories
When using edge branch, testing repository can be added as a tagged repository as shown above. Remember that, packages in testing repository have no support.

After upgrading to edge, the currently installed edge version i.e the build date that is attached to the edge release may be checked with command:
$ cat /etc/alpine-release
Setup your system and account
The alpine-sdk is a metapackage that pulls in the most essential packages used to build new packages. Also install and configure a way to elevate privileges, such as sudo or doas, and an editor, such as vi, nano, micro.
# apk add alpine-sdk
This would be a good time to create a normal user account for you to work in. To make life easier later, it's a good idea to add this user to the wheel group; operations that require superuser privileges can now be done with sudo or doas.
The aports tree is in git so before we clone it, let's configure git. Refer Development using git page for a quick reference.
Configure your global git config
Configure your name and email address in git. This name and email address will show up in all your commits:
$ git config --global user.name "Your Full Name" $ git config --global user.email "your@email.address"
Using git config without --global let you configure other details for a specific git repository.
For aports, configure git to use rebase instead of merge when you execute git pull:
$ git config pull.rebase true
Configure abuild
Abuild needs to be configured for both the system and user.
Edit the file /etc/abuild.conf as per requirements. Most of the defaults can be left alone, unless you are developing for a custom platform, in which case the comments in the file should guide you. The one field to edit is PACKAGER, so that you can get credit (or blame) for packages you create.
In order to use abuild
command The user executing abuild
must be a member of the abuild
group:
# addgroup <yourusername> abuild
For abuild a public/private rsa key pair is needed. The abuild-keygen
command from abuild package generates and configures the security keys.
$ abuild-keygen -a -i
