[jupyterhub] Minimum core managed nodes must be >= 4 ?

[asmacdo]

We’ve set our desired nodes and min nodes to 1, but we still have 4 nodes.

Is there additional configuration that overrides this?

Changing the desired_size after the cluster is deployed with Terraform will not have any impact.

To make changes effective, you need to set the min_size to 1. The desired_size is managed by Auto Scaling Groups (ASGs) once the node groups are created.

You can modify this in the AWS Console by editing the managed node group's min and desired sizes. If nodes still scale to 4, check the Cluster Autoscaler logs to see if pod requests triggered the scaling, particularly if there are pending pods that can't fit on one node.
