I have created a new EC2 without attaching key pair hence could not be able login. So plan to update the key pair alone but went wrong due to my approach as I just updated key_name parameter in the same TF template(main.tf) that had destroyed the existing EC2 and created new EC2 with key-pair.
But the requirement was just updated key pair not entire ec2. Please help me out on the steps.
Thanks in advance.
