Note that this example may create resources which cost money. In many scenarios, I want a security group I'm creating inside a module to include an ingress rule for a security group that was created in a different module, leading to ordering problems, and often resulting in failed terraform apply commands. Modules in Terraform are self-contained packages of Terraform configurations that are managed as a group. terraform-aws-security-group creates aws_security_group and aws_security_group_list resources based on input.
