CI/CD 概述
包含有关 OpenShift Container Platform 的 CI/CD 的信息
摘要
第 1 章 关于 CI/CD
OpenShift Container Platform 是面向开发人员的企业就绪 Kubernetes 平台，使组织能够通过 DevOps 实践（如持续集成(CI)和持续交付(CD)）自动化应用程序交付流程。为了满足您的机构需求，OpenShift Container Platform 提供以下 CI/CD 解决方案：
- OpenShift 构建
- OpenShift Pipelines
- OpenShift GitOps
1.1. OpenShift 构建
使用 OpenShift 构建时，您可以使用声明性构建过程创建云原生应用程序。您可以在用于创建 BuildConfig 对象的 YAML 文件中定义构建过程。此定义包括构建触发器、输入参数和源代码等属性。部署之后，BuildConfig 对象通常构建可运行的镜像并将其推送到容器镜像 registry。
- Docker 构建
- Source-to-image（S2I）构建
- Custom 构建
如需更多信息，请参阅了解镜像构建
1.2. OpenShift Pipelines
OpenShift Pipelines 提供了一个 Kubernetes 原生 CI/CD 框架，用于在其自己的容器中设计和运行 CI/CD 管道的每个步骤。它可以通过可预测的结果独立扩展以满足按需管道。
如需更多信息，请参阅 Red Hat OpenShift Pipelines。
1.3. OpenShift GitOps
OpenShift GitOps 是一个使用 Argo CD 作为声明性 GitOps 引擎的 Operator。它启用了多集群 OpenShift 和 Kubernetes 基础架构的 GitOps 工作流。使用 OpenShift GitOps，管理员可以在集群和开发生命周期中一致地配置和部署基于 Kubernetes 的基础架构和应用程序。
如需更多信息，请参阅 Red Hat OpenShift GitOps。
1.4. Jenkins
Jenkins 自动化了构建、测试和部署应用和项目的过程。OpenShift 开发者工具提供 Jenkins 镜像，它直接与 OpenShift Container Platform 集成。Jenkins 可通过使用 Samples Operator 模板或认证的 Helm Chart 在 OpenShift 上部署。
