cloudstack_firewall fails with json: unmarshal error

[samzehnder]

Hi there,

I run in an error when using the cloudstack_firewall ressource. The configuration is applied correctly but it seems like terraform fails to parse the state and fails with the error:

Error refreshing state: 1 error(s) occurred:

• cloudstack_firewall.default: cloudstack_firewall.default: json: cannot unmarshal string into Go struct field FirewallRule.startport of type int

Terraform Version

Terraform v0.9.4

Affected Resource(s)

• cloudstack_firewall

Terraform Configuration Files

provider "cloudstack" {
  # PROD
  api_url = "ommited"
  api_key = "ommited"
  secret_key = "ommited"
  http_get_only = true
  timeout = 3600
}

resource "cloudstack_firewall" "default" {
  ip_address_id = "6be820f2-3e34-40da-9de8-0f323b4a4a89"
  rule {
    cidr_list = ["195.8.198.0/23"]
    protocol  = "tcp"
    ports     = ["80", "22", "443"]
  }
}

Debug Output

not much more than this:
cloudstack_firewall.default: Refreshing state... (ID: 6be820f2-3e34-40da-9de8-0f323b4a4a89)

Expected Behavior

Firewallrules are applied, state is updated and can be processed further by terraform

Actual Behavior

Firewallrules are applied, state cannot be read by further terraform plan/apply runs

Steps to Reproduce

1. terraform apply => error occurs
2. terraform plan => error occurs

@samzehnder I noticed you already supplied a patch to the go-cloudstack package and that you already found out this is due to an API change wit CloudStack that happened quite a while ago. I'll have a look at your suggested fix and if that works out we'll update the dependency here as well.

Thanks and I'll get back to you shortly!
