Terraform: ssh remote connection private_key not used

[dverbeek84]

Hi i have a problems with connecting with ssh and the new private_key This is not working

connection {
  user = "centos"
  private_key = "${"file(/users/danny/.ssh/xxxxx")"
}

If you look at the output you see Private key: false

aws_instance.management-master (remote-exec):   Private key: false

When i use key_file i don't have the problem

connection {
  user = "centos"
  key_file = "/users/danny/.ssh/xxx"
}

aws_instance.management-master (remote-exec):   Private key: true

Hi @dverbeek84, not sure if this a transcription typo, but this:

private_key = "${"file(/users/danny/.ssh/xxxxx")"

is missing a closing set of braces - it should read:

private_key = "${file("/users/danny/.ssh/xxxxx")}"

If you change this does it resolve your problem? I am also trying to verify whether this is the case independently.

I'm trying to reproduce this using the configuration below, but it seems OK to me. I suspect that if you correct the file interpolation syntax as detailed in the previous message this will resolve the issue, since I _can_ replicate it in that case. I'll close this issue in anticipation of this resolving your issue - if it doesn't please feel free to reopen it!

provider "aws" {
    region = "us-west-2"
}

resource "aws_key_pair" "test_keypair" {
    key_name = "test_keypair"
    public_key = "${file("${path.module}/keys/id_rsa.pub")}"
}

resource "aws_instance" "test_instance" {
    ami = "ami-f0091d91"
    instance_type = "t2.micro"
    key_name = "${aws_key_pair.test_keypair.key_name}"

    connection {
        user = "ec2-user"
        private_key = "${file("${path.module}/keys/id_rsa")}"
    }

    provisioner "remote-exec" {
        inline = [
            "touch ~/provisioned"
        ]
    }

    tags {
        Name = "Terraform provisioner test instance"
    }
}

output "public_ip" {
    value = "${aws_instance.test_instance.public_ip}"
}

It was a typo in github not in the file itself.
But it is not working if you have version 0.6.6 of course :smile:. But after installing terraform 0.6.7 terraform just hangs for a long time...... :(

reverting to key_file has worked for me to resolve a similar (but possibly different) issue with private_key not working in my setup.

I saw it is closed but just a last comment here in case somebody else find this page as I did while google(ing)

this is working fine for me, using Openstack as provider and it has retry and timeout

resource "openstack_compute_instance_v2" "1_Windows2012R2" {
count = "1"
name = "Windows 2012 R2"
image_name = "win-2012-r2"
flavor_name = "m1.large"
network { name = "public" }
floating_ip = "${openstack_compute_floatingip_v2.1_Windows2012R2_ip.address}"
key_pair = "id_rsa"
security_groups = ["default"]

connection {
user = "Admin"
host = "${openstack_compute_floatingip_v2.1_Windows2012R2_ip.address}"
private_key = "/home/ecerquei/.ssh/id_rsa"
timeout = "10m"
}

provisioner "remote-exec" {
inline = [
"dir"
]
}
}
resource "openstack_compute_floatingip_v2" "1_Windows2012R2_ip" {
region = ""
pool = "10.8.172.0/22"
}

I don't understand how the private_key = "/home/ecerquei/.ssh/id_rsa" would work, when the value is supposed to be the contents of the file read for example with the file()

private_key - The contents of an SSH key to use for the connection. These can be loaded from a file on disk using the file() interpolation function. This takes preference over the password if provided.

@eduardocerqueira ?

[aleclarson]

The openstack_compute_instance_v2 docs suggest private_key can be a file path, which I assume is not true.

See here.
