Setting max instance capacity

eksctl supports the autoScaler.resourceLimits.maxInstanceCount field. You can use this setting to define the maximum number of instances the autoscaler can launch for a virtual node group.

Here’s an example cluster configuration:

 apiVersion: eksctl.io/v1alpha5
 kind: ClusterConfig
 
 metadata:
   name: example
   region: us-west-2
 
 nodeGroups:
   - name: ng1
     spotOcean:
       # ...
       autoScaler:
         resourceLimits:
           maxInstanceCount: 10
       # ...
 

In this example, the autoscaler won’t scale the virtual node group above 10 instances.
