Congratulations! You have completed this module. At this point, you know: 
恭喜!您已完成本模块。此时,您知道:

  • OpenShift® is an enterprise-ready Kubernetes container platform built for open hybrid cloud.  
    OpenShift® 是一个为开放混合云构建的企业级 Kubernetes 容器平台。
  • OpenShift is easier to use, integrates with Jenkins, and has more services and features.  
    OpenShift 更易于使用,与 Jenkins 集成,并提供更多服务和功能。
  • Custom resource definitions (CRDs) extend the Kubernetes API. 
    自定义资源定义 (CRDs) 扩展了 Kubernetes API。
  • CRDs paired with custom controllers create new, declarative APIs in Kubernetes. 
    CRDs 与自定义控制器配合使用,在 Kubernetes 中创建新的声明式 API。
  • Operators use CRDs and custom controllers to automate cluster tasks. 
    操作员使用 CRD(自定义资源定义)和自定义控制器来自动化集群任务。
  • A build is a process that transforms inputs into an object. 
    构建是一个将输入转换为对象的过程。
  • An ImageStream is an abstraction for referencing container images in OpenShift. 
    ImageStream 是 OpenShift 中用于引用容器镜像的抽象概念。
  • A service mesh provides traffic management to control the flow of traffic between services, security to encrypt traffic between services, and observability of service behavior to troubleshoot and optimize applications. 
    服务网格为服务之间的流量提供管理,控制流量流向,为服务间流量加密提供安全,以及提供服务行为可观察性以用于故障排除和应用程序优化。
  • Istio is a service mesh that supports four concepts of connection, security, enforcement, and observability. It is commonly used with Microservices applications. 
    Istio 是一种支持连接、安全、执行和可观察性四个概念的服务网格。它通常与微服务应用程序一起使用。
  • Istio provides service communication metrics for basic service monitoring needs: latency, traffic, errors, and saturation. 
    Istio 提供服务通信指标,以满足基本的服务监控需求:延迟、流量、错误和饱和度。
