AWS EC2-VPC Security Group Terraform module

Terraform module which creates EC2 security group within VPC on AWS.

These types of resources are supported:

Features

This module aims to implement ALL combinations of arguments supported by AWS and latest stable version of Terraform:

IPv4/IPv6 CIDR blocks
VPC endpoint prefix lists (use data source aws_prefix_list)
Access from source security groups
Access from self
Named rules (see the rules here)
Named groups of rules with ingress (inbound) and egress (outbound) ports open for common scenarios (eg, ssh, http-80, mysql, see the whole list here)
Conditionally create security group and all required security group rules ("single boolean switch").

Ingress and egress rules can be configured in a variety of ways. See inputs section for all supported arguments and complete example for the complete use-case.

If there is a missing feature or a bug - open an issue.

Usage

There are two ways to create security groups using this module:

Security group with predefined rules

module "web_server_sg" {
  source = "terraform-aws-modules/security-group/aws//modules/http-80"

  name        = "web-server"
  description = "Security group for web-server with HTTP ports open within VPC"
  vpc_id      = "vpc-12345678"

  ingress_cidr_blocks = ["10.10.0.0/16"]
}

Security group with custom rules

module "vote_service_sg" {
  source = "terraform-aws-modules/security-group/aws"

  name        = "user-service"
  description = "Security group for user-service with custom ports open within VPC, and PostgreSQL publicly open"
  vpc_id      = "vpc-12345678"

  ingress_cidr_blocks      = ["10.10.0.0/16"]
  ingress_rules            = ["https-443-tcp"]
  ingress_with_cidr_blocks = [
    {
      from_port   = 8080
      to_port     = 8090
      protocol    = "tcp"
      description = "User-service ports"
      cidr_blocks = "10.10.0.0/16"
    },
    {
      rule        = "postgresql-tcp"
      cidr_blocks = "0.0.0.0/0"
    },
  ]
}

Note about "value of 'count' cannot be computed"

Terraform 0.11 has a limitation which does not allow computed values inside count attribute on resources (issues: #16712, #18015, ...)

Computed values are values provided as outputs from module. Non-computed values are all others - static values, values referenced as variable and from data-sources.

When you need to specify computed value inside security group rule argument you need to specify it using an argument which starts with computed_ and provide a number of elements in the argument which starts with number_of_computed_. See these examples:

module "http_sg" {
  source = "terraform-aws-modules/security-group/aws"
  # omitted for brevity
}

module "db_computed_source_sg" {
  # omitted for brevity

  vpc_id = "vpc-12345678" # these are valid values also - "${module.vpc.vpc_id}" and "${local.vpc_id}"

  computed_ingress_with_source_security_group_id = [
    {
      rule                     = "mysql-tcp"
      source_security_group_id = "${module.http_sg.this_security_group_id}"
    }
  ]
  number_of_computed_ingress_with_source_security_group_id = 1
}

module "db_computed_sg" {
  # omitted for brevity

  ingress_cidr_blocks = ["10.10.0.0/16", "${data.aws_security_group.default.id}"]

  computed_ingress_cidr_blocks = ["${module.vpc.vpc_id}"]
  number_of_computed_ingress_cidr_blocks = 1
}

module "db_computed_merged_sg" {
  # omitted for brevity

  computed_ingress_cidr_blocks = ["10.10.0.0/16", "${data.aws_security_group.default.id}", "${module.vpc.vpc_id}"]
  number_of_computed_ingress_cidr_blocks = 3
}

Note that db_computed_sg and db_computed_merged_sg are equal, because it is possible to put both computed and non-computed values in arguments starting with computed_.

Conditional creation

Sometimes you need to have a way to create security group conditionally but Terraform does not allow to use count inside module block, so the solution is to specify argument create.

# This security group will not be created
module "vote_service_sg" {
  source = "terraform-aws-modules/security-group/aws"

  create = false
  # ... omitted
}

Examples

Complete Security Group example shows all available parameters to configure security group.
HTTP Security Group example shows more applicable security groups for common web-servers.
Disable creation of Security Group example shows how to disable creation of security group.
Dynamic values inside Security Group rules example shows how to specify values inside security group rules (data-sources and variables are allowed).
Computed values inside Security Group rules example shows how to specify computed values inside security group rules (solution for value of 'count' cannot be computed problem).

How to add/update rules/groups?

Rules and groups are defined in rules.tf. Run update_groups.sh when content of that file has changed to recreate content of all automatic modules.

Known issues

Due to an issue #1920 in AWS provider, updates to the description of security group rules are ignored by this module. If you need to update description after the security group has been created you need to recreate security group rule.
