Error with keys when running terraform apply

Question

When running terraform apply I get an error with keys. I am just learning terraform. I can't seem to find a solution online on how to fix this issue:

   Terraform does not automatically rollback in the face of errors.
   Instead, your Terraform state file has been partially updated with
   any resources that successfully completed. Please address the error
   above and apply again to incrementally change your infrastructure.

I tried going to AWS console and creating a keypair but that does not seem to help

Answer 1

From your machine, create the keypair using the command as follow ssh-keygen -f terraform-keys2

then your config should have resource aws_key_pair as below to it in aws

resource "aws_key_pair" "terraform-keys2" {
  key_name = "terraform-keys2"
  public_key = "terraform-keys2.pub"
}

Answer 2

With this error, please check if you have created the keypair terraform-keys2 in the region you are working on.

aws_instance.nginix: Error launching source instance: InvalidKeyPair.NotFound: The key pair terraform-keys2 does not exist status code: 400, request id: 993cc401-4c7a-4e4b-9630-71bc4b5729b0
