Cluster Autoscaler Addon

We strongly recommend using Cluster Autoscaler with the kubernetes version for which it was meant. Refer to the Cluster Autoscaler documentation compatibility matrix

Note that you likely want to change AWS_REGION and GROUP_NAME, and probably MIN_NODES and MAX_NODES. Here is an example of how you may wish to do so:

CLOUD_PROVIDER=aws
IMAGE=k8s.gcr.io/cluster-autoscaler:v1.1.0
MIN_NODES=1
MAX_NODES=5
AWS_REGION=us-east-1
GROUP_NAME="nodes.k8s.example.com"
SSL_CERT_PATH="/etc/ssl/certs/ca-certificates.crt" # (/etc/ssl/certs for gce)

addon=cluster-autoscaler.yml
wget -O ${addon} https://raw.githubusercontent.com/kubernetes/kops/master/addons/cluster-autoscaler/v1.8.0.yaml

sed -i -e "s@{{CLOUD_PROVIDER}}@${CLOUD_PROVIDER}@g" "${addon}"
sed -i -e "s@{{IMAGE}}@${IMAGE}@g" "${addon}"
sed -i -e "s@{{MIN_NODES}}@${MIN_NODES}@g" "${addon}"
sed -i -e "s@{{MAX_NODES}}@${MAX_NODES}@g" "${addon}"
sed -i -e "s@{{GROUP_NAME}}@${GROUP_NAME}@g" "${addon}"
sed -i -e "s@{{AWS_REGION}}@${AWS_REGION}@g" "${addon}"
sed -i -e "s@{{SSL_CERT_PATH}}@${SSL_CERT_PATH}@g" "${addon}"

kubectl apply -f ${addon}
