BigIP provider crash when virtual server configured to use a port list.

[ajchiarello]

Environment

• TMOS/Bigip Version: BIG-IP 14.1.4 Build 0.0.11 Final
• Terraform Version: 1.0.10
• Terraform bigip provider Version: 1.12.0

Summary

I've created a virtual_server using the bigip terraform provider. I needed it to use a port list rather than a single port, so I made that change in the GUI, and then ran a terraform plan to see what it would try to change (so I could tell terraform to ignore that change). Instead, the provider crashed when it attempted to refresh the virtual server resource.

Steps To Reproduce

Create a bigip_ltm_virtual_server resource. Go to the web interface and configure the virtual server to use a port list. Run a terraform refresh, plan, or apply.

Output:

╷
│ Error: Request cancelled
│
│   with bigip_ltm_virtual_server.consul,
│   on install-consul.tf line 55, in resource "bigip_ltm_virtual_server" "consul":

│ The plugin.(*GRPCProvider).ReadResource request was cancelled.

Error: The terraform-provider-bigip_v1.12.0 plugin crashed!

This is always indicative of a bug within the plugin. It would be immensely
helpful if you could report the crash with the plugin's maintainers so that it
can be fixed. The output above should help diagnose the issue.

ERRO[0009] 1 error occurred:
        * exit status 1

Expected Behavior

Ideally, that the terraform provider supported port lists for virtual servers. Minimally, that I can add one in the gui and tell terraform to ignore_changes on it. Minimally, that it doesn't crash the provider completely.

@ajchiarello - Please provide TF manifest to verify this issue at our end.

Here's the BIG-IP resources. In this, I do have a port defined under the virtual_server, because one is required to create the resource; as I said in the original post, changing it to a port list in the F5 and then running anything that triggers a terraform refresh will crash the provider.

resource "bigip_ltm_pool" "consul" {
  name     = "/K8S/${var.project_name}-pool"
  monitors = ["/K8S/https_8501"]
}

resource "bigip_ltm_pool_attachment" "consul_web" {
  for_each = local.consul_name_ip_map
  pool     = bigip_ltm_pool.consul.name
  node     = "${bigip_ltm_node.consul[each.key].name}:8501"
}

resource "bigip_ltm_node" "consul" {
  for_each = local.consul_name_ip_map
  name     = "/K8S/${each.key}"
  address  = each.value
}

resource "bigip_ltm_virtual_server" "consul" {
  name                       = "/K8S/${var.project_name}"
  destination                = var.consul_f5_ip
  ip_protocol                = "tcp"
  port                       = "8501"
  pool                       = bigip_ltm_pool.consul.name
  profiles                   = ["/Common/tcp"]
  source_address_translation = "automap"
}

I have raised BUG - 1068173, for this issue.

[ajchiarello]

Is there any timeline for resolving this bug?

[trinaths]

@ajchiarello - This issue is with another team. We raised this issue BUG - 1068173.

[gmouratidis]

Greetings, is there any updates on this topic or an ETA for a release covering this? We also have some usecases where portlist setup on VS via the TF provider would be required.

[trinaths]

@gmouratidis this issue must be resolved in BIGIP to be resolved from ansible. Please followup with BID 1068173

[ajchiarello]

@trinaths How would one go about following up on the bug ID?

[malacration]

I have the same need for port list configuration
