Terraform gcp firewall

This terraform module is used to create firewall on GCP.

We eat, drink, sleep and most importantly love DevOps. We are working towards strategies for standardizing architecture while ensuring security for the infrastructure. We are strong believer of the philosophy Bigger problems are always solved by breaking them into smaller manageable problems. Resonating with microservices architecture, it is considered best-practice to run database, cluster, storage in smaller connected yet manageable pieces within the infrastructure.

This module is basically combination of Terraform open source and includes automatation tests and examples. It also helps to create and improve your infrastructure with minimalistic code instead of maintaining the whole infrastructure code yourself.

We have fifty plus terraform modules. A few of them are comepleted and are available for open source usage while a few others are in progress.

Prerequisites

This module has a few dependencies:

• Terraform 1.x.x
• Go
• github.com/stretchr/testify/assert
• github.com/gruntwork-io/terratest/modules/terraform

Examples

IMPORTANT: Since the master branch used in source varies based on new modifications, we suggest that you use the release versions here.

Here are some examples of how you can use this module in your inventory structure:

Default subnet

module "firewall" {

source = "clouddrove/firewall/google"
version     = "1.0.0"

name                            = "test-firewall"
module_enabled                  = true
google_compute_firewall_enabled = true
project_id                      = var.gcp_project_id
network                         = module.vpc.vpc_id
description                     = "Creates firewall rule targeting tagged instances."
protocol                        = "TCP"
ports                           = ["80", "4440", "443", "22"]
source_ranges                   = ["0.0.0.0/0"]

}

Inputs

Name	Description	Type	Default	Required
allow	(Optional) The list of ALLOW rules specified by this firewall. Each rule specifies a protocol and port-range tuple that describes a permitted connection.	list(any)	[]	no
description	Creates Firewall rule targetting tagged instances	string	"Managed by clouddrove"	no
environment	Environment (e.g. prod, dev, staging).	string	""	no
google_compute_firewall_enabled	n/a	bool	true	no
label_order	Label order, e.g. sequence of application name and environment name,environment,'attribute' [webserver,qa,devops,public,] .	list(any)	[]	no
module_enabled	n/a	bool	true	no
name	Name of the resource. Provided by the client when the resource is created.	string	""	no
network	The name or self_link of the network to attach this firewall to.	string	""	no
ports	n/a	list(number)	[]	no
project_id	The project in which the resource belongs. If it is not provided, the provider project is used.	string	""	no
protocol	The IP protocol to which this rule applies. The protocol type is required when creating a firewall rule.	string	""	no
source_ranges	IP que será liberado para acessar	list(string)	[ "0.0.0.0/0" ]	no
source_tags	Nomes de tags que serão utilizadas para utilizar com esta regra de firewall	list(string)	[]	no

Outputs

Name	Description
id	Name of the resource. Provided by the client when the resource is created.
name	an identifier for the resource with format
self_link	The URI of the created resource.

Testing

In this module testing is performed with terratest and it creates a small piece of infrastructure, matches the output like ARN, ID and Tags name etc and destroy infrastructure in your AWS account. This testing is written in GO, so you need a GO environment in your system.

You need to run the following command in the testing folder:

  go test -run Test
