您可以将 Red Hat OpenShift GitOps 的轻量级版本与 MicroShift 搭配使用，通过安装 microshift-gitops RPM 软件包来帮助管理应用程序。您可以使用声明性 GitOps 引擎，在节点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。microshift-gitops RPM 软件包包含运行核心 Argo CD 所需的清单。
重要
Argo CD CLI 在 MicroShift 上不可用。这个过程安装基本的 GitOps 功能。
先决条件
- 已安装 MicroShift 版本 4.14 或更高版本。
- 配置了 250MB 的额外存储。
流程
运行以下命令，使用订阅管理器启用 GitOps 存储库：
sudo subscription-manager repos --enable=gitops-1.16-for-rhel-9-$(uname -m)-rpms
$ sudo subscription-manager repos --enable=gitops-1.16-for-rhel-9-$(uname -m)-rpmsCopy to Clipboard Copied! Toggle word wrap Toggle overflow 运行以下命令来安装 MicroShift GitOps 软件包：
