can't set different hostname with vsphere provider

[hashibot]

This issue was originally opened by @jeroenjacobs1205 as hashicorp/terraform#14659. It was migrated here as part of the provider split. The original body of the issue is below.

Affected Resource(s)

Please list the resources as a list, for example:

• vsphere_virtual_machine

I have particular use-case where the hostname needs to be configured differently from the vm name. I thought this was possible with customizations, seems not...

Snippet:

resource "vsphere_virtual_machine" "dns_instance" {

  count = "${var.count}"
  name = "${var.environment}-${var.name}-${format("%03d", count.index+1)}"
  domain = "${var.dns_domain}"
	dns_servers = "${split(",", var.dns_servers)}"
	dns_suffixes = "${split(",", var.dns_suffixes)}"

  vcpu   = "${var.vcpu}"
  memory = "${var.memory}"

  network_interface {
    label = "${var.vm_network}"
    ipv4_address = "${element(split(",", var.ips),count.index)}"
    ipv4_gateway = "${var.gateway}"
    ipv4_prefix_length = "${element(split("/",var.cidr),1)}"
  }

  disk {
    template = "${var.vm_template}"
    datastore = "${var.vm_datastore}"
    type = "thin"
  }

  custom_configuration_parameters = {
    role = "${var.role}"
    hostname = "${var.name}-${format("%03d", count.index+1)}"
  }

}

As you can see, the vm name in vsphere contains the environment in it's name. However, this should not be present in /etc/hostname.

I was hoping I could override this with the custom_configuration_parameters section, but "hostname" gets ignored.

I can barely find information which variables are valid within custom_configuration_parameters. I assume "hostname" is the correct one, but I'm not sure.

PS: Maybe the TF documentation should contain some info about the most trivial variables that are valid custom configuration parameters. It's just plain guesswork at the moment...

Hey @jeroenjacobs1205! As you might have seen, thanks to @ewypych we now have the capability to perform hostname customization. This will available in the next release.

Thanks!
