集群内核升级
功能介绍
该接口用于升级集群版本,实现版本优化、功能增强的业务需求。
支持如下升级类型:
-
同版本升级:升级集群的内核补丁。集群升级至当前版本的最新镜像,用于修复问题或优化性能。例如,集群版本为“7.10.2(7.10.2_24.3.3_0102)”,同版本升级后,集群版本会升级到7.10.2版本最新的镜像“7.10.2(7.10.2_24.3.4_0109)”(版本号仅做示例,非现网实际版本号)。
-
跨版本升级:升级集群的版本。集群升级至目标版本的最新镜像,用于功能加强或版本收编。例如,集群版本为“7.6.2(7.6.2_24.3.3_1224)”,跨版本升级后,集群版本会升级到7.10.2版本最新的镜像“7.10.2(7.10.2_24.3.4_0109)”(版本号仅做示例,非现网实际版本号)。
-
跨引擎升级:将Elasticsearch集群升级至OpenSearch集群。Elasticsearch集群升级至OpenSearch集群目标版本的最新镜像,用于引擎变更。例如,Elasticsearch集群版本为“7.10.2(7.10.2_24.3.3_0102)”,跨引擎升级后,Elasticsearch集群会升级到OpenSearch 1.3.6版本最新的镜像“1.3.6(1.3.6_24.3.4_0109)”(版本号仅做示例,非现网实际版本号)。该功能暂不支持。
接口约束
-
只有Elasticsearch和OpenSearch集群支持。
-
最多同时支持20个集群升级。
-
升级过程涉及数据迁移,单个节点的数据迁移的超时阈值为48小时,超时将导致升级失败。当集群数据量大时,建议手动调整数据迁移速率,避免在业务高峰期操作。

URI
POST /v1.0/{project_id}/clusters/{cluster_id}/inst-type/{inst_type}/image/upgrade
请求参数
参数 |
是否必选 |
参数类型 |
描述 |
---|---|---|---|
target_image_id |
是 |
String |
参数解释: 目标镜像版本ID。 约束限制: 不涉及 取值范围: 不涉及 默认取值: 不涉及 |
upgrade_type |
是 |
String |
参数解释: 升级类型。 约束限制: 不涉及 取值范围:
默认取值: 不涉及 |
indices_backup_check |
是 |
Boolean |
参数解释: 是否进行全量索引快照备份检测。升级过程中涉及数据迁移,快照备份可以避免因升级失败导致的数据丢失。 约束限制: 平台无法校验索引的具体内容以及备份时效性。建议人工检查备份是否超过一个月,如果超过请创建最新快照。 取值范围:
默认取值: true |
agency |
是 |
String |
参数解释: 委托名称,升级节点时需重新绑定网卡,当前账号需具备VPC资源的使用权限。通过配置IAM委托,使当前账号授权CSS服务访问其拥有的VPC资源。 约束限制: 不涉及 取值范围: 不涉及 默认取值: 不涉及 |
cluster_load_check |
否 |
Boolean |
参数解释: 是否进行集群负载检测。升级过程中的数据迁移及节点重启操作会占用集群资源,提前检测可避免因负载过高导致的升级失败。 检测项包括:
约束限制: 不涉及 取值范围:
默认取值: true |
batch_size |
否 |
Integer |
参数解释: 设置数据迁移并发度。提升数据迁移并发度可以加快升级进程,但是数据迁移会消耗IO性能,并发迁移数据节点越多,集群负载越高,会导致集群性能受影响。 约束限制: 不涉及 取值范围: 建议按需设置合适的并发度,推荐保持默认值1(节点),最大值小于数据节点数量的一半。 默认取值: 不涉及 |
