1.12.0 - Improved GameServer Validation

This is the 1.12.0 release of Agones.

A few things to note in this release:

  • The GameServer CRD now includes the full PodTemplateSpec json schema, to provide better up-front validation. This should be entirely backward compatible, but in case you run into issues, the helm configuration option gameservers.podPreserveUnknownFields is available to disable validation and field pruning.
    • If you are using Helm, you might need to update your Helm version and/or do a clean install to apply this update to your cluster if you already have a version of Agones installed, due to the size of the CRD update.
  • SDKWatchSendOnExecute has been moved to Beta, so by default you will get a copy of the most recent GameServer information with your initial SDK.WatchGameServer(...) request.
  • The ability to apply port allocation to multiple containers has moved from Beta to Stable!

Check the README for details on features, installation and usage.
