- Data sources allow Terraform to use information defined outside of Terraform, defined by another separate Terraform configuration, or modified by functions.
- Data sources are like resources, but they don't create anything, just get some data you can refer to.
- A data source is accessed via a special kind of resource known as a data resource, declared using a data block:
1data "aws_ami" "example" {
2 most_recent = true
3
4 owners = ["self"]
5 tags = {
6 Name = "app-server"
7 Tested = "true"
8 }
9}
- This data source get aws amis that are owned by the user, and have these appropriate names.
- This is how you would refer them later:
