keypair.tf

During the Terraform deployment, a custom SSH key pair will be created; in this file, we define some properties for it:

resource "tls_private_key" "mykey"
{
    algorithm = "RSA" 
    rsa_bits = 4096
}
resource "aws_key_pair" "keypair"
{
    key_name = "${var.key_name}"
    public_key = "${tls_private_key.mykey.public_key_openssh}"
}
output "mykey" {
  value = "${tls_private_key.mykey.private_key_pem}}"
  sensitive = true
}

The resource type we first define is an SSH private key:

 resource "tls_private_key" "privkey" {   algorithm = "RSA"   rsa_bits = 4096 }

We determine what kind of algorithm will be used and the key size in bits.

The next resource is the key pair as a bundle:

 resource "aws_key_pair" "keypair" {   key_name = "${var.key_name}" public_key ...
