Kubernetes Features

Service discovery and load balancing

No need to modify your application to use an unfamiliar service discovery mechanism. Kubernetes gives Pods their own IP addresses and a single DNS name for a set of Pods, and can load-balance across them.

不需要修改应用程序来使用不熟悉的服务发现机制。Kubernetes为pod提供了它们自己的IP地址和一组pod的一个DNS名称，并且可以在它们之间实现负载平衡。

Automatic bin packing

Automatically places containers based on their resource requirements and other constraints, while not sacrificing availability. Mix critical and best-effort workloads in order to drive up utilization and save even more resources.

根据容器的资源需求和其他约束自动放置容器，同时不牺牲可用性。混合关键工作负载和最佳工作负载，以提高利用率并节省更多资源。

Storage orchestration

Automatically mount the storage system of your choice, whether from local storage, a public cloud provider such as GCP or AWS, or a network storage system such as NFS, iSCSI, Gluster, Ceph, Cinder, or Flocker.

自动挂载您选择的存储系统，无论是本地存储、公共云提供商(如GCP或AWS，还是网络存储系统(如NFS、iSCSI、Gluster、Ceph、Cinder或Flocker)。

Self-healing

Restarts containers that fail, replaces and reschedules containers when nodes die, kills containers that don’t respond to your user-defined health check, and doesn’t advertise them to clients until they are ready to serve.

重新启动失败的容器，在节点死亡时替换和重新调度容器，杀死不响应用户定义的健康检查的容器，并且在它们准备好服务之前不会向客户端宣传它们。

Automated rollouts and rollbacks

Kubernetes progressively rolls out changes to your application or its configuration, while monitoring application health to ensure it doesn’t kill all your instances at the same time. If something goes wrong, Kubernetes will rollback the change for you. Take advantage of a growing ecosystem of deployment solutions.

Kubernetes逐步推出对应用程序或其配置的更改，同时监视应用程序的运行状况，以确保它不会同时杀死所有实例。如果出现问题，Kubernetes将为您回滚更改。利用不断增长的部署解决方案生态系统。

Secret and configuration management

Deploy and update secrets and application configuration without rebuilding your image and without exposing secrets in your stack configuration.

部署和更新秘密和应用程序配置，而无需重新构建映像，也无需在堆栈配置中公开秘密。

Batch execution

In addition to services, Kubernetes can manage your batch and CI workloads, replacing containers that fail, if desired.

除了服务之外，Kubernetes还可以管理批处理和CI工作负载，如果需要，还可以替换失败的容器。

Horizontal scaling

Scale your application up and down with a simple command, with a UI, or automatically based on CPU usage.

使用一个简单的命令、一个UI或基于CPU使用情况自动对应用程序进行上下伸缩。
