How do I create a SoftLayer Vlan using Terraform?

Question

I am able to create VLANs using control.softlayer.com (we have the automated VLAN ordering flag turned on). However, when I attempt to use the Terraform provider from github slash ibm-bluemix.github.io/tf-ibm-docs/v0.3-tf-v0.9.3/r/infra_vlan.html, I get an error. I am using the API key from my account, so permissions should be the same.

Here's the .tf file content:

resource "ibmcloud_infra_vlan" "dev_vlan_01" {
    name = "pancakes_dev_vlan_01"
    datacenter = "FRA02"
    type = "PRIVATE"
    subnet_size = 8
    router_hostname = "bcr01a.fra02"
}

Here's the error:

Error applying plan:

1 error(s) occurred:

* ibmcloud_infra_vlan.dev_vlan_01: 1 error(s) occurred:

* ibmcloud_infra_vlan.dev_vlan_01: Error creating vlan: SoftLayer_Exception_Public: Access Denied.  (HTTP 401)

the contents of my ~/.softlayer file are:

[softlayer]
username = <username as it appears in users list in control.softlayer.com>
api_key = <api key as it appears both in my Profile page and in the users list>

Thanks in advance!

Update 1:

It appears that the new build of the plugin no longer looks at ~/.softlayer. Makes sense that I'm getting 401s then - it looks like the plugin is being executed with no credentials. After looking at the code here https://github.com/IBM-Bluemix/terraform/blob/v0.3-tf-v0.9.3/builtin/providers/ibmcloud/provider.go I've tried setting the SL_USERNAME and SL_API_KEY environment variables to no apparent effect. I also tried adding a provider "bluemix" section with the credentials in it to my .tf file, also seemingly with no effect.

Update 2: Figured out that I need to be using the "vpn" username (not the username from the Users page) and now the environment variables are working. However, terraform apply results in a crash:

$ terraform apply

Terraform does not automatically rollback in the face of errors.
Instead, your Terraform state file has been partially updated with
any resources that successfully completed. Please address the error
above and apply again to incrementally change your infrastructure.

Answer 1

Here are all the traps I fell into:

• Account Pre-requisites: This will only work if someone from SoftLayer has turned on automatic VLAN ordering on your account.
• Credentials: the "username" you are supposed to use is the "API Username" from your Profile. Latest builds from https://github.com/IBM-Bluemix/terraform/tree/v0.3-tf-v0.9.3 does not respect ~/.softlayer, but I was able to pass the credentials using environment variables SL_USERNAME and SL_API_KEY
• Capitalization: I was capitalizing the datacenter name as in FRA02, which was causing a terraform crash. Switching it to fra02 made everything happy.
