Docker APK Build Environment

An alpine linux environment for building apk packages using docker.

See http://wiki.alpinelinux.org/wiki/Creating_an_Alpine_package for additional documentation and https://engineering.fundingcircle.com/blog/2015/04/28/create-alpine-linux-repository/ for some background about testing and signing packages.

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

Install Fast

We have created packages antlr, antlr4, srcml, srcslice, respectively for the alpinelinux packages by following the above steps. The source of these packages can be found in the corresponding branches in the [aports repository](https://github.com/yijunyu/aports).

Suppose you have already got an account at docker.io, e.g., yijun, then run the following commands, which will first create a local docker image fast:yijun, then upload it into the docker.io hub.
