Affected Resource(s)

• dme_dns_record

Terraform Configuration Files

resource "dme_dns_record" "dyn_record" {
  domain_id     = "domain ID"
  name          = "foo-dyndns"
  type          = "A"
  value         = "1.2.3.4"
  ttl           = 600
  dynamic_dns   = true
  password      = "aPassword"

Expected Behavior

value is currently a required parameter. I would expect it to be optional in case of dynamic_dns=true to avoid overriding the dynamic IP on the next terraform apply.

I would expect the following input to be accepted by making value optional:

resource "dme_dns_record" "dyn_record" {
  domain_id     = "domain ID"
  name          = "foo-dyndns"
  type          = "A"
  ttl           = 600
  dynamic_dns   = true
  password      = "aPassword"

Alternative would be to ignore the value when the record already exists.

Actual Behavior

On each terraform apply the IP address uploaded by my router is overriden by hardcoded value in terraform. With this we loose the dynamic capabilities.

Steps to Reproduce

1. terraform apply
2. modify the IP address either by the UI or with a dyndns client
3. terraform apply -> IP change from step 2 is lost.

As the value must be provided I prepared a PR where an init_value can be provided.
