Deploy Cluster Autoscaler on AWS

NOTE: If you are pulling from a private containers registry, replace the image name with the full URL to the docker image. E.g.

containers:
  - image: 'your-registry/cluster-autoscaler:your-version'

Run the command below to create the RBAC requirements to deploy Cluster Autoscaler on your cluster:

kubectl apply -f rbac-requirements.yaml

The following K8s resources will be created:

• A serviceAccount with name cluster-autoscaler in the kube-system namespace.
• A role in the kube-system namespace.
• A roleBinding which binds the serviceAccount created with the corresponding role.
• A clusterRole.
• A clusterRoleBinding which binds the serviceAccount created with the corresponding clusterRole.

Once you accomplish RBAC requirements, deploy Cluster Autoscaler on the cluster with one of the specifications below:

• 1 ASG Setup (use cluster-autoscaler-one-asg.yaml)
• Multiple ASG Setup (use cluster-autoscaler-multi-asg.yaml
• Master Node Setup (use cluster-autoscaler-run-on-master.yaml)
• Auto-Discovery Setup (use cluster-autoscaler-autodiscover.yaml)

You just need to run the command below:

kubectl apply -f DEPLOYMENT-SPECIFICATIONS.yaml
