terraform remote-exec provisioner hangs and fails running a simple command!

[Richard Mauri]

I have a terraform file provisioner that creates an ec2 atomic resource and then uploads a file to my atomic instance OK

I have a remote-exec provisioner to do a simple cat append command ; It is very slow (5 mins or so) and ultimately fails

partial terraform apply transcript

slow here.....then...

Error applying plan:

* Failed to upload script: Error reading script: EOF

Terraform does not automatically rollback in the face of errors.

Instead, your Terraform state file has been partially updated with

any resources that successfully completed. Please address the error

above and apply again to incrementally change your infrastructure.

Below is a prtial snippet of my .tf file

provider "aws" {

    access_key = "${var.access_key}"

    secret_key = "${var.secret_key}"

    region = "${var.region}"

}

resource "aws_instance" "atomic-server" {

    ami = "${lookup(var.ami, concat(var.region, "-", var.platform))}"

    instance_type = "${var.instance_type}"

    key_name = "${var.aws_key_name}"

    count = "${var.servers}"

    security_groups = ["wideopen"]

#    security_groups = ["${aws_security_group.atomic.name}"]

    connection {

        user = "${lookup(var.user, var.platform)}"

        key_file = "${var.key_path}"

    }

    tags {

        Name = "${var.tagName}-${count.index}"

    }

    provisioner "file" {

        source = "fedora_bashrc"

        destination  = "/home/fedora/fedora_bashrc"

    }

    provisioner "file" {

        source = "nomad"

        destination  = "/home/fedora/nomad"

    }

    provisioner "remote-exec" {

        inline = [

            "cat /home/fedora/fedora_bashrc >> /home/fedora/.bashrc",

#            "chmod a+x /home/fedora/nomad",

#            "sudo chmod a+w /tmp",

#            "sudo groupadd docker",

#            "sudo gpasswd -a fedora docker",

#            "sudo service docker restart",

        ]

    }

}

I tried with and without the trailing ","in the remote-exec inline command

Forgot to add this is on Terraform v0.6.6
