Hi @johnowens looking at the documentation for Amazon Linux 2022 it appears to based off of Fedora 35 which by default requires key pair types of ED25519. As of the current release of Packer and the Amazon Packer Plugin the only supported type for the Amazon builder is RSA.
However, we just merged in a new change to support ED25519 key types which should resolve this issue. To verify that this is indeed the issue I tested against the following template and confirmed that using a dev build of the latest plugin code fixes the issue.
I’ll follow up with the team on making an Amazon plugin release.
source "amazon-ebs" "basic-example" {
region = "us-west-2"
source_ami = "ami-044065b5480679567"
instance_type = "t2.small"
ssh_username = "ec2-user"
ssh_agent_auth = false
temporary_key_pair_type = "ed25519"
ami_name = "packer_AWS {{timestamp}}"
}
build {
sources = [
"source.amazon-ebs.basic-example"
]
provisioner "shell"{
inline = ["echo Hello from Amazon Linux 2022"]
}
}
