本文档详细介绍了如何从集群中删除 OpenShift Serverless。

第 1 章 删除 OpenShift Serverless 概述

如果需要从集群中删除 OpenShift Serverless，您可以手动删除 OpenShift Serverless Operator 和其他 OpenShift Serverless 组件。在删除 OpenShift Serverless Operator 之前，您必须删除 Knative Serving 和 Knative Eventing。

  • 在 OpenShift Container Platform 上具有集群管理员权限，或者在 OpenShift Dedicated 上具有集群或专用管理员权限。
  • 安装 OpenShift CLI (oc) 。

流程

  1. 删除 KnativeEventing CR： 

    $ oc delete knativeeventings.operator.knative.dev knative-eventing -n knative-eventing

  2. 在该命令运行完成且已从 knative-eventing 命名空间中移除所有 Pod 后，删除命名空间： 

    $ oc delete namespace knative-eventing
