## Kubernetes Docker in Docker Deployment with `act_runner`

Registers Kubernetes pod runners using [offline registration](https://forgejo.org/docs/v1.21/admin/actions/#offline-registration), allowing the scaling of runners as needed.

NOTE: Docker in Docker (dind) requires elevated privileges on Kubernetes. The current way to achieve this is to set the pod `SecurityContext` to `privileged`. Keep in mind that this is a potential security issue that has the potential for a malicious application to break out of the container context.
