I just started learning pulumi and I am having trouble in using the existing keypair to the ec2 instance I have created. I've been searching and reading for hours now but still could not find the answer. I found this documentation, https://www.pulumi.com/docs/reference/pkg/aws/ec2/keypair/, lack of detail and example on how to use this. Example existing KeyPair on AWS Name: MyExampleKeyPair ID: key-0f0e4

import pulumi
import pulumi_aws as aws 

size = 't2.micro'
ami = aws.get_ami(most_recent="true",
				  owners=["amazon"],
				  filters=[{"name":"name", "values":["amzn-ami-hvm-*"]}]
				)

group = aws.ec2.SecurityGroup('webserver-secgrp',
							  description="Enable HTTP access",
							  ingress=[
							  			{ 'protocol': 'tcp', 'from_port': 22, 'to_port': 22, 'cidr_blocks': ['0.0.0.0/0'] },
							  			{ 'protocol': 'tcp', 'from_port': 80, 'to_port': 80, 'cidr_blocks': ['0.0.0.0/0'] }
							  		  ]
								)

user_data = """
#!/bin/bash
echo "Hello, World!" > index.html
nohup python -m SimpleHTTPServer 80 &
"""

server = aws.ec2.Instance('webserver-www',
						  instance_type=size,
						  vpc_security_group_ids = [group.id],
						  user_data=user_data,
						  ami=ami.id
						  )

pulumi.export('publicIp', server.public_ip)
pulumi.export('publicHostName', server.public_dns)

My question is how am I going to add that on the code above? I've been trying different code but still not successful in adding the existing keypair.

Hi @average-nest-71706 Welcome to Pulumi! Let me know what you've tried and I can help you triage why it's not working

Hi @broad-dog-22463 What confuses me is the line of code here:

@staticmethod
def get(resource_name: str, id: str, opts: Optional[ResourceOptions] = None, arn: Optional[str] = None, fingerprint: Optional[str] = None, key_name: Optional[str] = None, key_name_prefix: Optional[str] = None, key_pair_id: Optional[str] = None, public_key: Optional[str] = None, tags: Optional[Mapping[str, str]] = None) -> KeyPair

Hi @average-nest-71706 So that's if you want to look up an existing keypair - you need to do the following there aws.ec2.KeyPair.get() on that

Oh I see.. After that, I did pulumi preview and got this error. "Preview failed: resource 'key-0f0e4b...' does not exist" These keypair is generated from the ec2 instance I manually provisioned before. deployer = aws.ec2.KeyPair.get("FirstKeyPair", id="key-0f0e4bf5b08639dad") Do I still need to do pulumi import?

pulumi import aws:ec2/keyPair:KeyPair deployer FirstKeyPair

so it's a manually created keypair that you already know the details of - the benefit of bringing this under pulumi management would just be to reference an ID that you know about I would suggest you can just set the KeyPair as part of your instance without the need to look it up to unblock you The alternative here would be to create a new KeyPair that is under Pulumi's management and will be created as part of te Pulumi run

Isn't a KeyPair manually created?

import pulumi
import pulumi_aws as aws

deployer = aws.ec2.KeyPair("deployer", public_key="ssh-rsa AAAAB3NzaC1yc2EAAAADAQABAAABAQD3F6tyPEFEzV0LX3X8BsXdMsQz1x2cEikKDEY0aIj41qgxMCP/iteneqXSIFZBp5vizPvaoIR3Um9xK7PGoW8giupGn+EPuxIA4cDM4vzOqOkiMPhz5XK0whEjkVzTo4+S0puvDZuwIsdiW9mxhJc7tgBNL0cYlWSYVkz4G/fslNfRPW5mYAM49f4fhtxPb5ok4Q2Lg9dPKVHO/Bgeu5woMc7RY0p1ej6D4CKFE6lymSDJpW0YHX/wqE9+cfEauh7xZcG0q9t2ta6F6fmX0agvpFyZo8aFbXeUBr7osSCJNgvavWbM/06niWrOvYX2xwWdhXmXSrbX8ZbabVohBK41 <mailto:email@example.com|email@example.com>")

it is not created unless you tell it to be

Ok so here's what I did. I used puttygen to generate a rsa-ssh then do:

Enc_key = "ssh-rsa somrandomeautogeneratedkeyhereAAAAEBRGRWQrgc"
deployer = aws.ec2.KeyPair("deployer", public_key=Enc_Key)

server = aws.ec2.Instance('webserver-www',
						  instance_type=size,
						  vpc_security_group_ids = [group.id],
						  user_data=user_data,
						  ami=ami.id,
						  key_name=deployer
						  )

At first it give me an error because deployer value on key_name is not returning the key pair name. So I removed that and do "pulumi up", it was successful but ec2 instance generated still don't have a key pair assigned. I also checked the Key Pair on aws and it generated a key pair for me named "deployer-2f63432". What I did next is updated the aws.ec2.Instance and added key_name="deployer-2f63432" and there, I saw that my ec2 instance now have an assigned keypair.

that's the one!

Thank you @broad-dog-22463
