# query dhcp services, match a name

locals {
  ids = data.ibm_pi_dhcps.dhcps.servers[*].network_id
  names = data.ibm_pi_dhcps.dhcps.servers[*].network_name
  dhcp_id_from_name = matchkeys(local.ids, local.names, ["dhcpserver"])[0]
}

provider "ibm" {
  ibmcloud_api_key = "..."
  region           = "tor"
  zone             = "tor01"
}

data "ibm_pi_dhcps" "dhcps" {
  pi_cloud_instance_id = "..."
}

output dhcps {
  value = data.ibm_pi_dhcps.dhcps
}

output dhcp_id {
  value = local.dhcp_id_from_name
}

Note: this may be incorrect TF, but, it does panic so I figure even if I have errors, it shouldn't panic, so I'm uploading it as-is.

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.

Expected Behavior
