EKS issue when adding node group with t4g class instance



We got an issue when we tried to add a node group in EKS with t4g class instance

AutoScalingGroupInvalidConfiguration - Amazon EC2 Autoscaling does not support the requested instanceType t4g.medium.

I check and t4g are available in my region (eu-west-3) I successfully set a t4g class instance by manually edition a launch configuration in an other node group.

Maybe you have forgot a condition somewhere when you release this new type of instance ?

Is there any difference between working node group and not-working node group? You should check which AZs are configured to each node group. Some instance types is not supported in the recently launched AZ.

node group are exactly the same (I test it with terraform and manually)

node group can deploy instance in the 3 AZ (eu-west-3a, b, c) I also check t4g instance are available in EC2 etc, i can set it manually by editing the launch configuration of the ASG created by EKS (if I first ask m6g instance for exemple)

As I can do it manually by cheating EKS, i suppose it's only a software limitation / bug
