allowedInstanceTypes

The instance types to apply your specified attributes against. All other instance types are ignored, even if they match your specified attributes. You can use strings with one or more wild cards, represented by an asterisk (`*`), to allow an instance type, size, or generation. The following are examples: `m5.8xlarge`, `c5*.*`, `m5a.*`, `r*`, `*3*`. For example, if you specify `c5*`,Amazon EC2 will allow the entire C5 instance family, which includes all C5a and C5n instance types. If you specify `m5a.*`, Amazon EC2 will allow all the M5a instance types, but not the M5n instance types. If you specify `AllowedInstanceTypes`, you can't specify `ExcludedInstanceTypes`. Default: All instance types
