From 11c1a8c8c9b2741d18dc337d5573d7a342e4faa9 Mon Sep 17 00:00:00 2001 From: Mark Mandel Date: Thu, 15 Mar 2018 17:33:55 -0700 Subject: [PATCH] GameServerSet Implementation GameServerSets are the basic building block for Fleets. GameServerSets will be allow Fleet migrations to occur, similarly to how ReplicaSets allow Deployments to migrate one image type to another. This has not been formally documented, as this will likely be an internal CRD, and not (widely) used externally.
