  ----
  <1> `name` must comply with the `rfc6335` service name syntax.
  <2> `zones` must conform to the definition of a `subdomain` in `rfc1123`. The cluster domain, `cluster.local`, is an invalid `subdomain` for `zones`.
  <3> A maximum of 15 `upstreams` is allowed per `forwardPlugin`.

negative.code: $ oc edit dns.operator/default
  ----
  +
  This allows the Operator to create and update the ConfigMap named `dns-default` with additional server configuration blocks based on `Server`. If none of the servers has a zone that matches the query, then name resolution falls back to the upstream DNS servers.
