kohrar opened a new issue #32:
URL: https://github.com/apache/cloudstack-terraform-provider/issues/32
Greetings everyone.
I ran into an issue where the assigned network_id doesn't get saved in the
terraform.tfstate file. As a result, subsequent terraform applies will
destroy/recreate the IP addresses because it thinks the network_id has changed.
Here is how I create an IP address
```
resource "cloudstack_ipaddress" "public_ip" {
count = "${var.num_vms_to_create}"
vpc_id = "${cloudstack_vpc.default.id}"
network_id = "${cloudstack_network.mynet.id}"
}
```
When applying this on multiple runs, Terraform will show the following (note
that network_id is being added even though the resource is created properly in
CloudStack):
```
Terraform will perform the following actions:
# cloudstack_ipaddress.public_ip[2] must be replaced
-/+ resource "cloudstack_ipaddress" "public_ip" {
~ id = "c823415a-32d4-4fe1-ac7d-65e5c38b5a6b" -> (known
after apply)
~ ip_address = "10.44.121.58" -> (known after apply)
~ is_source_nat = false -> (known after apply)
+ network_id = "0aa28065-2d46-4367-a7c0-0e065218aea5" # forces
replacement
+ project = (known after apply)
~ tags = {} -> (known after apply)
# (2 unchanged attributes hidden)
}
```
The terraform.tfstate file lists the IP address with an empty network_id
string.
```
{
"mode": "managed",
"type": "cloudstack_ipaddress",
"name": "public_ip",
"provider":
"provider[\"registry.terraform.io/cloudstack/cloudstack\"]",
"instances": [
{
"index_key": 0,
"schema_version": 0,
"attributes": {
"id": "2bdbc636-f6cd-47cc-b462-ae76351b993e",
"ip_address": "10.44.120.53",
"is_portable": false,
"is_source_nat": false,
"network_id": "", <----- shouldn't be empty
"project": "",
"tags": {},
"vpc_id": "5df887ba-9085-4d4b-a613-e6a7ba2e5ad4",
"zone": null
},
"sensitive_attributes": [],
"dependencies": [
"cloudstack_network.mynet",
"cloudstack_network_acl.default",
"cloudstack_vpc.default"
]
},
```
# Workaround
I was able to 'fix' this issue by removing the conditional
[`d.GetOk("network_id")`](https://github.com/apache/cloudstack-terraform-provider/blob/main/cloudstack/resource_cloudstack_ipaddress.go#L167)
and always setting `network_id` based on the `Associatednetworkid` value from
the CloudStack-go library. I'm not sure why that condition would be failing
though.
Any advice? Thanks!
