web-server-terraform

A simple web server terraform module for enabling blue-green deployments in AWS using terraform. This would work hand-in-hand with a shared configuration that would create and supply the details of all the shared resources required by this module. An example can be found here

Usage

  default_sg_id = aws_security_group.default.id
  default_subnet_id = aws_subnet.default.id
  key_id = aws_key_pair.auth.id
  aws_region = var.aws_region
}

output "web_server_a_address" {
  value = module.web_server_a.address
}

output "web_server_a_zone_id" {
  value = module.web_server_a.zone_id
