Hi, fuelers! In accordance to policy of API changing in Fuel components established in this mail thread [1] the purpose of this notice is to inform everyone concerned about such modifications pertaining to Nailgun cluster upgrade extension that is going to be landed into upstream.
New handler of HTTP requests for copying of VIPs from cluster under the upgrade to seed cluster is going to be added [2]. This handler is accessible by URL (omitting here the root part for Nailgun API) '/clusters/<cluster_id>/upgrade/vips/' where '<cluster_id>' is indicator of seed cluster. The reason for introducing the separate handler (before the operation was done as part of copying of network settings which in turn is triggered by cluster clone action) is that, as described here [3], copying of VIPs must be done for cluster with assigned nodes, thus, in context of upgrade, after calling to reassign nodes handler. The handler supports POST operation and accepts no data payload as all needed information is retrieved from cluster link object created on cloning of original cluster. In case of success response with empty body and 200 HTTP status code is returned. In case when cluster object with given '<cluster_id>' is not found in data base 404 code is returned, and in case when validation for the inbound request has failed the status code of response is 400.
