从 k8s 上卸载 KubeSphere

从 k8s 上卸载 KubeSphere

您可以使用 kubesphere-delete.sh 将 KubeSphere 从您现有的 Kubernetes 集群中卸载。复制 GitHub 源文件并在本地机器上执行此脚本。警告： 卸载意味着 KubeSphere 会从您的 Kubernetes 集群中移除。此操作不可逆并且没有任何备份，请谨慎操作。​​#!/usr/bin/env bashfunction delete_sure(){ cat << eof$(echo -e "\033[1;36mNote:\033[0m")Delete the KubeSphere cluster, including the module kubesphere-system kubesphere-devops-system kubesphere-monitoring-system kubesphere-logging-system openpitrix-system.eofread -p "Please reconfirm that you want to delete the KubeSphere cluster.
