Cluster Autoscaler for Civo Cloud

The cluster autoscaler for Civo Cloud scales worker nodes within any specified Civo Cloud Kubernetes cluster.

Configuration

As there is no concept of a node group within Civo Cloud's Kubernetes offering, the configuration required is quite simple. You need to set:

  • Your Civo Cloud API Key
  • The Kubernetes Cluster's ID (not the name)
  • The region of the cluster
  • The minimum and maximum number of worker nodes you want (the master is excluded)

See the cluster-autoscaler-standard.yaml example configuration, but to summarise you should set a nodes startup parameter for cluster autoscaler to specify a node group called workers e.g. --nodes=1:10:workers.

The remaining parameters can be set via environment variables (CIVO_API_KEY, CIVO_CLUSTER_ID and CIVO_REGION) as in the example YAML.

It is also possible to get these parameters through a YAML file mounted into the container (for example via a Kubernetes Secret). The path configured with a startup parameter e.g. --cloud-config=/etc/kubernetes/cloud.config. In this case the YAML keys are api_url, api_key, cluster_id and region.
