How to fix The provider provider.aws does not support data source

Question

I am trying to get the id of the default security group created when creating a vpc using terraform.

Here's what I tried:

data "aws_default_security_group" "default" {
  vpc_id = module.ecs_vpc.vpc_id
}

but I am getting this error:

The provider provider.aws does not support data source "aws_default_security_group"

can someone help me on this?

Answer 1

To get default security group you just use aws_security_group:

data "aws_security_group" "default" {
  name = "default"
  vpc_id = module.ecs_vpc.vpc_id
}

Alternatively, you want to manage default group using TF, you can get it using (not data):

resource "aws_default_security_group" "default" {
  vpc_id = data.aws_vpc.default.id
}
