Increase configurable runtime maximum worker node count #858

Closed ebensom closed 1 week ago

ebensom commented 1 month ago

Description

The maximum allowed autoscalerMax parameter should be increased to 300 for enterprise plans (aws, gcp, azure, sap-converged-cloud). In the future, when multiple worker groups can be specified as parameters, KEB should validate if the sum of autocalerMax values of all worker groups don't exceed 300

Reasons

Kyna runtime artificially limits cluster nodes scalability, however in practice, the practical maximum nodes a cluster can withstand is in the 150-300 range.

Right now we have autoscalerMax == 80

Summary how it will look. Azure Lite wasn't changed.

aws gcp azure sap-converged-cloud preview azure lite
autoscalerMax maximum 300 300 300 300 300 40

@ebensom I've also included the preview plan in this change, unless it was specifically not mentioned in the issue and shouldn't be changed.
