SSH key for AWS Autoscaling Group node not working - amazon-web-services

Question

So I created the autoscaling group using the following Terraform files:
Autoscaling group:
resource "aws_autoscaling_group" "orbix-mvp" {
desired_capacity = 1
launch_configuration = "${aws_launch_configuration.orbix-mvp.id}"
max_size = 1
min_size = 1
name = "${var.project}-${var.stage}"
vpc_zone_identifier = ["${aws_subnet.orbix-mvp.*.id}"]
tag {
key = "Name"
value = "${var.project}-${var.stage}"
propagate_at_launch = true
}
tag {
key = "kubernetes.io/cluster/${var.project}-${var.stage}"
value = "owned"
propagate_at_launch = true
}
}
Launch configuration:
# This data source is included for ease of sample architecture deployment
# and can be swapped out as necessary.
data "aws_region" "current" {}
# EKS currently documents this required userdata for EKS worker nodes to
# properly configure Kubernetes applications on the EC2 instance.
# We utilize a Terraform local here to simplify Base64 encoding this
# information into the AutoScaling Launch Configuration.
# More information: https://docs.aws.amazon.com/eks/latest/userguide/launch-workers.html
locals {
orbix-mvp-node-userdata = <<USERDATA
#!/bin/bash
set -o xtrace
/etc/eks/bootstrap.sh --apiserver-endpoint '${aws_eks_cluster.orbix-mvp.endpoint}' --b64-cluster-ca '${aws_eks_cluster.orbix-mvp.certificate_authority.0.data}' '${var.project}-${var.stage}'
USERDATA
}
resource "aws_launch_configuration" "orbix-mvp" {
associate_public_ip_address = true
iam_instance_profile = "${aws_iam_instance_profile.orbix-mvp-node.name}"
image_id = "${data.aws_ami.eks-worker.id}"
instance_type = "c5.large"
name_prefix = "${var.project}-${var.stage}"
security_groups = ["${aws_security_group.orbix-mvp-node.id}"]
user_data_base64 = "${base64encode(local.orbix-mvp-node-userdata)}"
key_name = "devops"
lifecycle {
create_before_destroy = true
}
}
So I've added the already generated SSH key under name devops to the launch configuration. I can SSH into manually created EC2 instances with that key, however I can't seem to SSH into instances created by this config.
Any help is appreciated, thanks :)
