I have created ssh_key by

ssh-keygen -t rsa -b 4096 -C "[email protected]" -f terraform_ec2_key

and put that terraform_ec2_key in my terraform file and it looks like this

provider "aws" {
 region = "us-west-2"
}



resource "aws_key_pair" "terraform_ec2_key" {
  key_name = "terraform_ec2_key"
  public_key = "${file("terraform_ec2_key.pub")}"
  
}

resource "aws_instance" "myfirst" {
  ami = "ami-830c94e3"
  instance_type = "t2.micro"
  key_name = aws_key_pair.terraform_ec2_key.key_name
  tags = {   
     name = "terraformec2"
  }
}

and when i did terraform apply command it was apllied succesfully and the instance was created but when i connect to the instance using connect command provided by aws

ssh -i terraform_ec2_key [email protected]

I am getting [email protected]: Permission denied (publickey). Here what I have tried chmod 400 terraform_ec2_key but not working also open port 22 from inbound rule but still i am getting same error is there anything am I missing?

Based on the comments.

The code is perfectly fine in itself. The issue was caused by wrong ami-id. Instead of ubuntu AMI, other was used, for example, amazon linux 2. This will result in the Permission denied (publickey) as amazon linux 2 uses ec2-user user, not `ubuntu.
