副本集始终尝试将实际状态匹配到期望状态。 - Autoscaling enables scaling as needed at the cluster or node level, and the pod level.
自动扩展能够在集群、节点和 Pod 级别按需进行扩展。 - Autoscaler types include horizontal pod (HPA), vertical pod (VPA), and cluster (CA).
自动扩展类型包括水平 Pod(HPA)、垂直 Pod(VPA)和集群(CA)。 - Rolling updates roll out app changes in a controlled and automated way.
滚动更新以受控和自动化的方式推出应用程序变更。 - Rolling updates and rollback can be performed using all-at-once and one-at-a-time strategies.
滚动更新和回滚可以使用一次性和逐个执行策略执行。 - ConfigMaps are used to provide variables for your application.
ConfigMaps 用于为您的应用程序提供变量。 - Secrets are used to provide sensitive information to your application.
