Cloudscaler

Cloudscaler is a Kubernetes operator that scales cloud resources up or down using custom CRDs. It supports Kubernetes resources like deployments and cron jobs and aims to extend support to cloud resources like Compute Engine and Cloud SQL on GCP.

This project is inspired by kube-downscaler.

Getting Started

Installation via Helm

1. Install the Chart

   helm install cloudscaler oci://ghcr.io/kubecloudscaler/kubecloudscaler/kubecloudscaler --namespace cloudscaler-system

2. Create a Scaler Custom Resource (CR)

   # Example: Downscales all deployments (excluding kube-system) to 0 from 19:00 to 21:00 (Paris time) daily.
   apiVersion: kubecloudscaler/v1alpha1
   kind: K8s
   metadata:
     name: k8s-sample
   spec:
     periods:
       - time:
           recurring: true
           days:
             - all
           startTime: "19:00"
           endTime: "21:00"
           timezone: "Europe/Paris"
         minReplicas: 0
         maxReplicas: 10
         type: "down"

3. Apply the Configuration

   kubectl apply -f <scaler-CR-file.yaml>
