How to conditionally create a resource based on a string

Terraform
1

Hi,
How can I dynamically create a resource based on a passed variable which is not a simple “true/false” boolean?

For example this pseudo-code:

resource "something" {
   if var.day != Sunday
...
}
2

The standard idiom is:

resource "some_thing" "blue" {
  count = var.day != "Sunday" ? 1 : 0
}

Something to watch out for - once you do this, you have to change any references elsewhere in your Terraform code to some_thing.blue to some_thing.blue[0].
