LogScale pods in this architecture are designed to have a one-to-one relationship with the underlying EKS node. However, the Humio Operator does not currently support autoscaling operations while the underlying Kubernetes nodes do. In most cluster sizes, the desired count of pods is less than the maximum number of kubernetes nodes for that tier. For example, in a small:advanced architecture, the desired digest pod count is six while the maximum EKS digest node count is twelve. In this situation, you can expand kubernetes by updating the node count in cluster_size.tpl to a new target count that should not exceed the maximum EKS node count.

After saving cluster_size.tpl, run:

terraform apply -target module.logscale -var-file $TFVAR_FILE
