Auto Scaling Groups, Launch Template and EC2 instance with multiple ENIs with different configurations.

Question

Is there a way to add a launch template that defines EC2 instances with multiple ENIs that have different configurations (for each ENI) to an Auto Scaling Group? or is it a limitation in ASGs?

Answer

It depends on the setting, for example, you can't select multiple different subnets (since AutoScaling ignores the subnet setting). But you can select different security groups. Can you give some more details on what your usecase is?

Specifically for the multiple subnets issue, you can workaround it with this method
