AWS CloudFormation could be very helpful for creating template-able infrastructure definitions.
One of many sections of a template, is the Enter Parameters, or just Parameters as CloudFormation calls it. It is a part block that llows for person outlined variables to be consumed by the template.
When testing, it may be helpful to specify default values right here.
This may be achieved by including the Default key and setting a worth.
Parameters:
surroundings:
Sort: String
Default: DEV
vpcid:
Sort: String
Default: "vpc-123456789123456a"
