Automating VM creation via Terraform

eperez539

I'm starting to use Terraform to provision new vms and followed the configuration from the xenorchestra provider for Terraform:
https://terra-farm.github.io/provider-xenorchestra/index.html
but running into following issue:

Error: websocket: bad handshake

  on main.tf line 7, in data "xenorchestra_template" "template":
   7: data "xenorchestra_template" "template" {

Is there anything I need to enable on XenOrchestra so the websocket connection works?

We'll take a look after our monthly release! ping @julien-f

@eperez539 Hi, the WebSocket API of Xen Orchestrea, is always enabled, please check the URL and, if it still does not work, ask help on Terraform

@julien-f Yes, I had the xcp-ng host ip instead of XO ip. After changing that, getting different error now:

Error: jsonrpc2: code -32000 message: unknown error from the peer

  on main.tf line 53, in resource "xenorchestra_vm" "base":
  53: resource "xenorchestra_vm" "base" {

Here is what my tf file looks like:

provider "xenorchestra" {
  url = "ws://XO_IP_HERE"
  username = "USERNAME"
  password = "PASSWORD"
}

data "xenorchestra_template" "template" {
  name_label = "Ubuntu Bionic Beaver 18.04"
}

data "xenorchestra_pif" "pif" {
  device = "eth0"
  vlan = -1
}

resource "xenorchestra_cloud_config" "base" {
  name = "cloudconfig"
  template = <<EOF

}

resource "xenorchestra_vm" "base" {
    memory_max = 1073733632
    cpus  = 2
    cloud_config = "${xenorchestra_cloud_config.base.template}"
    name_label = "TerraformVM"
    name_description = "Created by Terraform Script"
    template = "${data.xenorchestra_template.template.id}"
    network {
	    network_id = "${data.xenorchestra_pif.pif.network}"
    }

    disk {
      sr_id = "388ccc18-9b21-22cc-dfa9-db4c8c3a4959"
      name_label = "Terraform_disk_imavo"
      size = 32212254720
    }
}

Do you happen to see what I'm doing wrong here? Thanks

I'm not familiar with Terraform, but I can tell you that you can get more info about an unknown error from the peer error in XO on the Settings > Logs page.

@eperez539
The line #cloud-init should be replaced with #cloud-config. The official xen terraform template is wrong

@newknowledge Thanks, I'll try it out later.
