What's the best way to debug the output?

[maktouch]

Is there any way we can generate a file or output to the shell?

I tried

resource "null_resource" "validator2" {
  triggers {
    user-data = "${module.coreos-config.user-data}"
  }

  provisioner "local-exec" {
    command = <<-EOF
rm -rf output.txt
cat << EOT > output.txt
${module.coreos-config.user-data}
EOT
    EOF
  }
}

but var!private_ipv4 is blank (but it does generate okay in the curl validator)

Cheers
