When creating a

new eks.Cluster

how can I add scaling policies, e.g. "scale up when average CPU utilization is > 70%" ?

In principle you can do something like:

const scalingPolicy = new aws.autoscaling.Policy("scaleup", {
    targetTrackingConfiguration: {
        predefinedMetricSpecification: {
            predefinedMetricType: "ASGAverageCPUUtilization",
        },
        targetValue: 75,
    },
    autoscalingGroupName: asgName,
});

However, it looks like we don't currently make it easy to get the

asgName

that is used by the NodeGroup(s) that

new eks.Cluster

and

new eks.NodeGroup

create. I'll open an issue to track exposing that name so this is easier to stitch together. You'll also want to make sure you specify appropriate

minSize

and

maxSize

on the NodeGroup/Cluster.

thanks
