Setup

To sign packages you'll need a key pair. To generate a pair of keys for this purpose run:

# builds an image and starts a container
make build
# generate keys
~/bin/setup.sh

Building a Package

Run make build to start the docker environment. In the build environment cd to the package directory which contains an APKBUILD file and run the build.

cd /work/<repo>/<package>
# Condtionally rebuild checksums if files has changed
abuild checksum
# Run the build
abuild -c -r -P /target

The built packages will be in ./target on the host.

Indexing and Signing

cd /target/<repo>/<arch>/
apk index -o APKINDEX.tar.gz *.apk
abuild-sign APKINDEX.tar.gz

Testing the Package

make test
apk add <package>@custom
