Terraform module which creates the VPC and EC2 resource on AWS

Terraform module which creates VPC resources and EC2 on AWS.

These types of resources are supported:

• VPC
• Subnet
• Route
• Route table
• Internet Gateway
• NAT Gateway
• Bastion Host

VPC

By default this modules creates the VPC with two public subnets and two private subnets with NAT gateways on each Private subnets. Internet Gateway is associated with public Subnets.

module "main-vpc" {
  source     = "https://github.com/karan6190/terraform-aws-infra/tree/master/modules/vpc"
  ENV        = "${var.ENV}"                  #productEnv
  AWS_REGION = "${var.AWS_REGION}"
  VPC_NAME   = "${var.VPC_NAME}"             #productID
  az1        = "${var.AWS_REGION}a"
  az2        = "${var.AWS_REGION}b"
}

Bastion Host

Bastion host helps us to Jump into the Instances in the private subnets. So this module launches the Instance in the public subnet which act as a jump server. By default Bastion host is launched with attached Administrative access policy and Security group (to access it over SSH)

module "bastion" {
  source         = "https://github.com/karan6190/terraform-aws-infra/tree/master/modules/bastion"
  ENV            = "${var.ENV}"
  AWS_REGION     = "${var.AWS_REGION}"
  VPC_NAME       = "${var.VPC_NAME}"                     #productID
  vpc_id         = "${module.main-vpc.vpc_id}"           #productVPC
  public_subnets = "${module.main-vpc.public_subnets-1}"
  keyname        = "bastion-key"                         #Key name
  pubkey         = "ssh-rsa xxxxxxxxxxxxxxxxxxxxxxx"     #public key
}
