A GitHub Action to build ingress-nginx container images from source using the chainguard-forks/ingress-nginx repository.

This repository contains a manually-triggered GitHub Actions workflow that:

1. Clones chainguard-forks/ingress-nginx at a specified release tag
2. Compiles the ingress controller, debug tool, and pre-stop hook for both amd64 and arm64
3. Builds a multi-platform Docker image and pushes it to ghcr.io

1. Go to the Actions tab
2. Select the Build ingress-nginx from source workflow
3. Click Run workflow
4. Enter the release tag to build (e.g. controller-v1.12.1)
5. Click Run workflow

The resulting image will be published to:

ghcr.io/<owner>/ingress-nginx:<release-tag>
