Renovate APK Index Server

This project aims to create a http server for renovate to query apk packages of the wolfi project.

Usage

For every release a container image is built and stored in the github container registry: docker run github.com/hown3d/renovate-apk-indexer

$ renovate-apk-indexer -help
Usage of renovate-apk-indexer:
  -apk-index-url string
        url of the apk index to get the package information from (default "https://packages.wolfi.dev/os/x86_64/APKINDEX.tar.gz")
  -update-interval int
        update interval of the apk package index in hours (default 4)

API

The server provides an endpoint for /<PACKAGE_NAME>, which returns the package information of <PACKAGE_NAME> in the format that renovate custom datasources expects

Wildcard Version API

An additional endpoint is provided at /wildcardVersion/<PACKAGE_NAME_WITH_WILDCARD_VERSION>. The wolfi APK index uses an unusual naming scheme where the version is provided within the package name, it is not easily possible for renovate to track version updates for those packages:

E.g. These are all valid package names in the wolfi APK index. Note that the base name without the number does not necessarily contain the most recent version:

argo-cd
argo-cd-compat
argo-cd-repo-server
argo-cd-2.9
argo-cd-2.9-compat
argo-cd-2.9-repo-server
argo-cd-2.10
argo-cd-2.10-compat
argo-cd-2.10-repo-server

nodejs
nodejs-18
nodejs-20
nodejs-22

To use the wildcard version endpoint, you can provide a single '*' at the point where the renovate-apk-indexer should expect a version number. Be aware that this will skip the base-package-name if there is no suffix on the wildcard string. This is a technical limitation, see explaination at /wildcardVersion/argo-cd*

Endpoint Request	Expected package name searches
/wildcardVersion/argo-cd*	will only match argo-cd-<number>, not argo-cd or argo-cd-<number>-compat This is a technical limitation to prevent the regex to match argo-cd-compat. If the suffix of the wildcard is empty it won't consider "non-number" matches for the suffix
/wildcardVersion/argo-cd*compat	will only match argo-cd-<number>-compat and argo-cd-compat
/wildcardVersion/argo-cd-*-compat	will only match argo-cd-<number>-compat and argo-cd-compat
/wildcardVersion/nodejs*	will only match nodejs-<number>, not nodejs. This is a technical limitation, see explaination of /wildcardVersion/argo-cd*

APK Index updates

By default, the server updates it's packages every 4 hours.

Healthchecks

Liveness and Readiness probe endpoints are available at /livez and /readyz.
