A Terraform security group module for just HTTPS, useful for external ELB instances.

• TCP 443 (HTTPS)

• security_group_name - The name for your security group, e.g. bluffdale_web_stage1
• vpc_id - The VPC this security group should be created in.
• source_cidr_block - The source CIDR block, defaults to 0.0.0.0/0 for this module.

You can use these in your terraform template with the following steps.

1. Adding a module resource to your template, e.g. main.tf

module "sg_web" {
  source = "github.com/terraform-community-modules/tf_aws_sg//sg_https_only"
  security_group_name = "${var.security_group_name}-https"
  vpc_id = "${var.vpc_id}"
  source_cidr_block = ["${var.source_cidr_block}"]
}

2. Setting values for the following variables, either through terraform.tfvars or -var arguments on the CLI

• security_group_name
• vpc_id
• source_cidr_block
