Terraform module to create AWS AutoScaling group and accompanying resources
Requires:
- terraform:
>= 0.13.0, < 0.14.0 - provider aws:
>= 2.68, < 4.0
- (Optionally) Launch Configuration instead of Launch Template
- Launch Template
- AWS AutoScaling group
Also may be used pre-created Launch Configuration or Launch Template
Only VPC AutoScaling groups supported.
