Similar EC2 Instance Types

Introduction

Handling of similar instance types is done in aws-operator since version 8.3.1, which has been introduced with Giant Swarm release v11.2.0 .

Read more about the use of similar instance types in our general article about node pools.

aws-operator creates an Auto Scaling Group (ASG) for every node pool. If the creator of the node pool activates the use of similar instance types, aws-operator looks up a list of similar instance types and configures the ASG to use all of them. The authoritative lookup list can be found in the aws-operator source.

Type mapping

If the type you are using for your node pool is not contained in the list above, activating the use of similar instance types has no effect.
