kruise-game-api

Filtering query and update operation API for kruise-game resources.

Overview

• This repository provides three request ways: command line, REST interface, and go language package to implement filtering and updating of kruise-game resources.
• The filter syntax is based on this repository: structured-filter-go.
• GameServer implemented the following Scene filters:

Key	Value Type	Filtered Field	Filter Examples
namespace	String Filter	/metadata/namespace	{"namespace": {"$in":["minecraft", "terraria"]}}
opsState	String Filter	/spec/opsState	{"opsState": {"$eq": "None"}}
updatePriority	Number Filter	/spec/updatePriority	{"updatePriority": {"$ne": 0}}
deletionPriority	Number Filter	/spec/deletionPriority	{"deletionPriority": {"$ne": 0}}
currentState	String Filter	/status/currentState	{"currentState": {"$eq": "Ready"}}
currentNetworkState	String Filter	/status/networkStatus/currentNetworkState	{"currentNetworkState": {"$eq": "Ready"}}

• GameServerSet implemented the following Scene filters:

Key	Value Type	Filtered Field	Filter Examples
namespace	String Filter	/metadata/namespace	{"namespace": {"$in":["minecraft", "terraria"]}}
images	String Array Filter	[/spec/gameServerTemplate/spec/containers[0].name+","+/spec/gameServerTemplate/spec/containers[0].image, /spec/gameServerTemplate/spec/containers[1].name+","+/spec/gameServerTemplate/spec/containers[1].image, ...]	{"images": {"$all":["minecraft,itzg/minecraft-server:java21", "sidecar,busybox:latest"]}}

• Use JSON Patch as update syntax.
