From ee16c094472ee988b85aa81ce8fa9f5da8e61ad9 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Harald=20Jens=C3=A5s?= Date: Tue, 25 Jun 2019 14:41:02 +0200 Subject: [PATCH] Allow per-subnet DNSNameServers for ctlplane network Add a new option ``dns_nameservers`` in the subnet sections for the undercloud ctlplane network. By default the option is not set, and in that case the ``undercloud_nameservers`` are used, maintaining the current behaviour. This decouples the nameservers used on the undercloud and the ones used for the overcloud nodes. In a DCN setting different DNS server may be preferred per-site.
