Test Infra Repo

---

📌 Overview

The Test Infra repository provides an isolated GitHub Actions--based automation framework for testing Kubernetes pull requests for IPVS-related changes.

It enables maintainers to:

• Checkout a specific PR from upstream repo
• Test changes made in Kubernetes repo mirror
• Execute validation and test workflows

This keeps CI logic separate from the Kubernetes upstream repository hosted at k8sIPvS/kubernetes

⚙️ Workflow Description

The primary automation logic resides in:

.github/workflows/basic_k8s.yml

Workflow Responsibilities

1. Trigger on:
   • Manual dispatch (workflow_dispatch) for better controll over batches of changes to be testes
2. Accept input parameter:
   • pr_number (optional) - fetches PR at given number from upstream Kubernetes repo at github.com
   • branch (optional) - branch in k8sIPvS/kubernetes with your changes
3. Execute pipeline steps:
   • Checkout repository
   • Fetch PR branch (if provided)
   • Checkout your branch by given name, default master
   • Run build/test steps
   • Output logs

🚀 Example Use Case

Testing Kubernetes PR #12345:

1. Dispatch workflow
2. Input 12345
3. Leave branch as 'master'
4. Workflow:
   • Clones upstream
   • Checks out PR
   • Runs validation
   • Reports status
