Can't create a dnat rule with computed IP address

[pkleanthous-zz]

Hi there,

When I'm trying to create a dnat rule with a computed ip address the resource fails.
If I re-run Terraform, the resource succeeds.

Terraform Version

Terraform v0.10.8

Affected Resource(s)

• vcd_dnat

If this issue appears to affect multiple resources, it may be an issue with Terraform's core, so please mention this.

Terraform Configuration Files

resource "vcd_dnat" "demo-server-ssh" {
  edge_gateway    = "Internet_ABC"
  external_ip     = "1.2.3.4"
  port            = 22
  internal_ip     = "${vcd_vapp_vm.demo-vm-1.ip}"
  translated_port = 22
  depends_on      = ["vcd_vapp_vm.demo-vm-1"]
}

Debug Output

* vcd_dnat.demo-server-ssh: Error completing tasks: &errors.errorString{s:"Error setting DNAT rules: &errors.errorString{s:\"error reconfiguring Edge Gateway: API Error: 400: [ 28086172-7092-44bb-9137-802416f16cf1 ] validation error on field 'gatewayServiceConfigurationSpec.natSpec.ruleList[1].translatedIp': String value should not be empty\"}"}

Expected Behavior

It should create the relevant resource

Actual Behavior

Terraform apply fails

Steps to Reproduce

Please list the steps required to reproduce the issue, for example:

1. terraform apply

This should work now with using newer network block in vcd_vapp_vm resources if using POOL ip allocation mode. DHCP could also work, but #316 details what are the issues with DHCP (in short vCD cannot guarantee that guest works and reports the IP it got)

@pkleanthous, if you are still interested in getting DHCP IP, you could try and check https://github.com/terraform-providers/terraform-provider-vcd/pull/436 PR and see if it works for you
