Hi,
I am referring to https://www.terraform.io/docs/provisioners/remote-exec.html#script-arguments to install the Nginx web server on the remote server.
cat main.tf
variable “region” {
default = “us-west1-a” // We’re going to need it in several places in this config
}
provider “google” {
credentials = “whcdrupalproject.json”
project = “whcdrupalproject”
region = “us-west1-a”
}
resource “google_compute_instance” “whcdrupal8” {
count = 1 // Adjust as desired
name = “whcdrupal8” // yields “test1”, “test2”, etc. It’s also the machine’s name and hostname
machine_type = “f1-micro” // smallest (CPU & RAM) available instance
zone = “us-west1-a” // yields “europe-west1-d” as setup previously. Places your VM in Europe
boot_disk {
initialize_params {
image = “centos-7”
}
}
network_interface {
network = “default”
access_config {
// Ephemeral IP - leaving this block empty will generate a new external IP and assign it to the machine
}
}
provisioner “file” {
source = “script.sh”
destination = “/tmp/script.sh”
}
provisioner “remote-exec” {
inline = [
“chmod +x /tmp/script.sh”,
“/tmp/script.sh args”,
]
}
}
I have the below script.sh file locally. I want it to be pushed to the remote server and execute it there.
#cat script.sh
#!/bin/bash
yum -y install nginx
Port 22 is open and please find the below details.

I ran terraform apply “whcdrupalproject.tfplan” it did not run the script.sh file remotely instead it reported Error: timeout - last error: dial tcp :22: connect: connection refused 
Am I missing anything in the above main.tf file? Any help will be highly appreciated and thanks in advance. I look forward to hearing from you.
Best Regards,
Kaushal
