Setting up ssh keys for EC2 instance on AWS

 

 

 

 

create ssh key pair

ssh-keygen -f my-keypair

this creates 2 files my-keypair & my-keypair.pub in the current directory

use puttygen to convert my-keypair to my-keypair.ppk

we'll use my-keypair.pub on EC2 instance

end user/clients will use private key -- my-keypair.ppk

 

# create EC2 instance via Terraform

# creating test ec2 instance for using ssh keypair made with TF

resource "aws_instance" "mam_test1" {

  ami           = "ami-xxxxxxxx"

  instance_type = "t2.micro"

  security_groups =["sg-yyyy" ]

  associate_public_ip_address =false

  subnet_id = "subnet-zzzzzz"

  key_name = "my-keypair"

  tags = {

    Name = "my_keypair"

  }

}

resource "aws_key_pair" "may-keypair" {

  key_name = "my-keypair"

  public_key = "${file("my-keypair.pub")}"

 

}

output "mam_test1ip" {

  value=aws_instance.mam_test1.private_ip

}

Once the instance is created use the my-keypair.ppk to connect to EC2 instance.
