If a user does not already have a CI/CD system in place, they can leverage SUSE Rancher Continuous Delivery (SUSE Rancher CD) which incorporates the use of SUSE Rancher project Fleet. SUSE Rancher workloads run by developers is a Continuous Integration and/or Continuous Delivery pipeline. A robust CI/CD pipeline is critical to ensure agile development and rapid delivery of new software releases to

OPENSHIFT PIPELINES Red Hat OpenShift Pipelines 是一个基于 Kubernetes 资源的云原生的持续集成和持续交付（continuous integration and continuous delivery，简称 CI/CD）的解决方案。它通过提取底层实现的详情，使用 Tekton 构建块进行跨多个平台的自动部署。Tekton 引入了多个标准自定义资源定义 (CRD)，用于定义可

可以通过定制应用镜像来实现持续集成、持续交付、部署。开发人员可以通过 Dockerfile 来进行镜像构建，并结合 持续集成(Continuous Integration) 系统进行集成测试， 而运维人员则可以直接在生产环境中快速部署该镜像，甚至结合 持续部署(Continuous Delivery/Deployment) 系统进行自动部署。 而且使用 Dockerfile 使镜像构建透明化，不仅仅开发团队可以理解应用运行环境，也方便 SSH 服务，无法通过用户名和密码 直接登录到容器中。 本章小结 326 CI/CD 持续集成(Continuous integration)是一种软件开发实践，每次集成都通过自动化的构建（包括 编译，发布，自动化测试）来验证，从而尽早地发现集成错误。 持续部署（continuous deployment）是通过自动化的构建、测试和部署循环来快速交付高质 量的产品。 与 Jenkins

converting high precision continuous values to low precision discrete values. Take a look at figure 2-3. It shows a sine wave and an overlapped quantized sine wave. The sine wave is continuous, a high precision Figure 2-4: Quantizing floating-point continuous values to discrete unsigned values. The continuous values range from xmin to xmax, and are mapped to continuous values in [0, 2b - 1] (in the above figure = 3, hence the quantized values are in the range [0, 7]. For the purpose of quantization, the continuous values are also clamped to be in the range [xmin, xmax]. Solution: Note that we have to map all
