cluster-autoscaler/aws: Unable to get instance type

[koooge]

Hi there ✋
I tried to set new ASG's launch template option to "Combine purchase options and instances". But it failed to scale up due to the missing instance type. Isn't this option supported yet?

This is not supported yet. We need to consider price model for long time at this moment since the way fleet abstract is different from the nodegroup abstract in the past.

Fleet support OnDemand/ Spot and different node flavors in one node group. Currenctly, ca use node group to differentiate node flavors.

In this case, CA does support multi node groups, If you want to use that way, please just create one ASG for one type of node. As I know, user create one for OnDemand and one for Spot. Enable scaling down to 0 for Spot ASG and always keep few nodes for OnDemand.

Please track status on following issues and probably just close this one. Thanks!
