## GitOps Continuous Delivery with Argo and Codefresh BRANDON PHILLIPS | CODEFRESH ## I nfo slide (not for presentation) Original Abstract: GitOps is the gold standard for managing and deploying Kubernetes application drift, and traceability through the engineering process. New: GitOps Continuous Delivery with Argo and Codefresh Description: Never make a manual change again. In this talk we’ll show how to use use GitOps to achieve reliable, and fast releases time and time again. Rather than pushing changes, Argo pulls and syncs code changes to a cluster. When combined with Codefresh’s CI/CD components we can get

Argo CD Application is a Custom Resource (CR) that defines the app in a declarative manner ☐ Name ☐ Cluster ☐ Git repository ☐ Synchronization Policy - Applications can be deployed from Argo CD GUI or CLI (argocd or kubectl or oc) apiVersion: argoproj.io/v1alpha1 kind: Application metadata:

存储库中开发和维护软件的核心原则应用到创建和管理集群和应用程序配置文件。 ## 第 2 章 关于 RED HAT OPENSHIFT GITOPS Red Hat 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 Red Hat OpenShift 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。Red Hat OpenShift GitOps 基于开源项目 Argo CD，为上游提供的功能提供类似的功能，并提供额外的自动化功能，集成到 Red Hat OpenShift Container Platform 中，以及 Red Hat OpenShift Container Platform OpenShift GitOps 使用 Argo CD 来维护集群资源。Argo CD 是一个开源声明工具，用于应用程序的持续部署(CD)。Red Hat OpenShift GitOps 将 Argo CD 实现作为一个控制器，以便持续监控 Git 存储库中定义的应用程序定义和配置。然后，Argo CD 将这些配置的指定状态与集群中的实时状态进行比较。 Argo CD 报告与指定状态不同的配置。报

UNINSTALLING RED HAT OPENSHIFT OPENSHIFT GITOPS Uninstalling the Red Hat OpenShift GitOps Operator is a two-step process: 1. Delete the Argo CD instances that were added under the default namespace of the Red Hat OpenShift GitOps Operator

control plane 工作负载，包括此命名空间中的默认 Argo CD 实例。 使用 GitOps control plane 工作负载，您可以通过在集群中创建多个隔离的 Argo CD 实例来安全地并声明性地隔离基础架构工作负载，并完全控制 Argo CD 实例的功能。另外，您可以在多个开发人员命名空间中以声明性方式管理这些 Argo CD 实例。通过使用污点，您可以确保只有基础架构组件在这些节点上运行。 [Image](/uploads/documents/f/b/d/0/fbd0d455ec283e1515aacbb68e86a26c/p7_1.jpg) ## 注意 在用户命名空间中安装的所有其他 Argo CD 实例都无权在基础架构节点上运行。 #### 1.1. 将 GITOPS CONTROL PLANE 工作负载移到基础架构节点 您可以将 Red Hat OpenShift GitOps Tolerations。  ## 注意 在默认 Argo CD CR 中手动添加节点选择器和 Tolerations 都会被 GitOpsService CR 中的切换和容限覆盖。 #### 1.2. 将 GITOPS OPERATOR POD 移到基础架构节点
