Autoscaling Native Kubernetes Workers

This tutorial demonstrates how to use autoscaling in Spacelift, an open-source platform that allows you to automatically adjust the number of workers in a cluster based on queue length. The process involves installing a Spacelift Worker Pool Controller, Prometheus Exporter, and KEDA ScaledObject in the cluster. It also requires creating a worker pool in Spacelift using Certificate Signing Request (CSR) files and an API key for authentication. Finally, you need to create a namespace and secrets for the worker pool controller and Prometheus exporter, install the Helm chart, and create a KEDA ScaledObject to monitor queue length and scale the worker pool accordingly.
