Github Actions - Self Hosted Agents on AKS

This repo provides instructions and configuration to setup Self Hosted Agents for Github running on an AKS cluster. It was derived from this article by John Bohannon. This project utilizes terraform and helm to provide support for a repeatable infrastructure as code approach. The process can also be orchestrated through an Github workflow.

Setup

Fork this repo and pull your fork to your computer

Cd into the repo

Ensure you have the following dependencies:

Run the setup.sh script

  • Syntax: . ./setup.sh [-c CLUSTER_NAME] [-g RESOURCE_GROUP_NAME] [-s SUBSCRIPTION_ID] [-r REGION] (the extra dot is important)
  • make setup_cmd provides an example version

This script does the following: - Create a service principal for use by terraform - Create a storage account to keep the terraform state - Create a resource group where your AKS cluster will be deployed - Save service principal and other provided variables in github secrets

If running locally:

This uses the repo makefile to create your AKS cluster, create an ACR, and deploy the runner to the cluster

Next steps

  • dynamically set repo owner/repo name
  • check for GH_TOKEN before deploying
  • remove helm install note
  • check for all other variables in makefile (gh secret get?)
  • add workflow / instructions
  • Validate setup for an organization
  • Multiple node pool
  • Cluster autoscaling
  • Virtual nodes?
