terraform-aws-dynamic-subnets

what

• Support use of tags by label modules

why

• Interoperability with all modules

what

• Add README.yaml

why

• Standardize README

what

• Allows the ability to override the max number of subnets to create.

why

For some regions with many availability zones the amount of subnets gets extreme. This allows the ability to override the max number of subnets to create. Still defaults to all if nothing is supplied.

what

• Fix README
• Fix make targets

why

• Use standard README template
• Use / instead of : in make targets

what

• Removed provider "aws"

why

• Not necessary here, should be used in higher-level modules
• Prevents inheriting provider settings from higher-level modules
• Becomes an issue when testing locally if we use the AWS security keys like this (not the best practice, but people use it for testing):

provider "aws" {
  region     = "${var.region}"
  access_key = "XXXXXXXXXXXXX"
  secret_key = "XXXXXXXXXXXXX"
}

At the same time, this code in terraform-aws-dynamic-subnets:

provider "aws" {
  region = "${var.region}"
}

throws the error:
module.subnets.provider.aws: No valid credential sources found for AWS Provider.

what

• Losen version constraint

why

• This is the change in required version syntax in order to be able to work with the Terraform Jenkins module
• it is related to the issue https://github.com/cloudposse/terraform-aws-jenkins/issues/11.

Add Continuous Integration

what

• Validate terraform code
• Add build status badge

why

• Improve code quality/consistency

Add Flag to Enable/Disable NAT Gateway

what

• Permit NAT Gateway to be disabled

why

• Sometimes only public subnets will be used. If that's the case, the NAT gateways do not provide any value and add additional cost.

what

• Rename repo

why

• To conform to community standard: https://www.terraform.io/docs/registry/modules/publish.html

Get the Internet Gateway attached to the VPC from AWS as a data source

Place NAT Gateways into public subnets

Update tf_subnets with cidr_block input
