Warning
This documentation covers the legacy mode of ARC (resources in the actions.summerwind.net namespace). If you're looking for documentation on the newer autoscaling runner scale sets, it is available in GitHub Docs. To understand why these resources are considered legacy (and the benefits of using the newer autoscaling runner scale sets), read this discussion (#2775).
By default, actions-runner-controller uses cert-manager for certificate management of Admission Webhook. Make sure you have already installed cert-manager before you install. The installation instructions for the cert-manager can be found below.
After installing cert-manager, install the custom resource definitions and actions-runner-controller with kubectl or helm. This will create an actions-runner-system namespace in your Kubernetes and deploy the required resources.
Kubectl Deployment:
# REPLACE "v0.25.2" with the version you wish to deploy
