Error after running terraform apply

[friendshipmarker]

I'm following the guide here for bootstrapping terraform, https://itnext.io/bootstrapping-kubernetes-clusters-on-aws-with-terraform-b7c0371aaea0 . After execution of terraform apply, i get the following error. I ssh into the machine 35.81.x.x and see that the /home/ubuntu/admin.conf has a permission of root:root still as though the chown command isn't being respected from the main.tf in the ../modules/cluster/main.tf file.

│ Error: Error running command 'alias scp='scp -q -i ~/.ssh/id_rsa -o StrictHostKeyChecking=no -o UserKnownHostsFile=/dev/null'
│ scp [email protected]:/home/ubuntu/admin.conf /Users/alluser/aws/terraform-kubeadm/selected-lark.conf >/dev/null
│ ': exit status 1. Output: scp: /home/ubuntu/admin.conf: Permission denied

Did something happen with a recent update? Running on version

module "cluster" {
source = "weibeld/kubeadm/aws"
version = "~> 0.2.4"
}

From what I see the admin.conf file is owned by root and other users do not have read access to it.
scp cannot elevate its privileges on the remote server, so a better option is to use rsync
I replaced lines 256 and 257 in .terraform\modules\cluster\main.tf with

alias rsync='rsync --rsync-path="sudo rsync" -e "ssh -q -i ${var.private_key_file} -o StrictHostKeyChecking=no -o UserKnownHostsFile=/dev/null"'
rsync ubuntu@${aws_eip.master.public_ip}:/home/ubuntu/admin.conf ${local.kubeconfig_file} >/dev/null

This worked for me.
I will open a Pull Request with this change, so the code owner can review it and merge it

I am getting the following error on my local machine as well as the ec2 master node:

@C02FGA9JMD6M terraform-kubeadm % kubectl --kubeconfig admin.conf get nodes
The connection to the server localhost:8080 was refused - did you specify the right host or port?

as well as the already mentioned scp error, but was able to copy the config file with rsync.

@friendshipmarker @mrpaff @greenszpila If you encounter this error, please log in to the node with SSH and post the output of:

tail -n 20 /var/log/cloud-init-output.log

This includes the logs of the bootstrap script, so we can see what's going on.

I'm working on fixing these issues.
