Add support for AWS r8i and r8i-flex instance types #8509
Description
Which component are you using?: cluster-autoscaler
Is your feature request designed to solve a problem? If so describe the problem this feature should solve.: Add two new instance types of r8i and r8i-flex from AWS
Describe the solution you'd like.: ec2_instance_types.go maintains statically a list of all AWS instance types. These new types can be added to this file.
Describe any alternative solutions you've considered.: N/A
Additional context.: my cluster autoscaler configuration must not use the dynamic instance types feature due to organisation restriction. Adding these types allow my cluster to use them in nodegroups.
