Hi @GautamGohel

Could you please confirm if the EC2 instance type was required as t2.micro?
Usually, all labs ask for t3.micro.

You need to create a tls_private_key resource and reference the public key in the aws_key_pair block:

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

resource "aws_key_pair" "devops_kp" {
  key_name   = "devops-kp"
  public_key = tls_private_key.devops_kp.public_key_openssh
}
