linux安裝KubeSphere

介紹

KubeSphere 是在目前主流容器調度平臺 Kubernetes 之上構建的企業級分布式多租戶容器平臺，提供簡單易用的操作界面以及向導式操作方式，在降低用戶使用容器調度平臺學習成本的同時，極大減輕開發、測試、運維的日常工作的復雜度，旨在解決 Kubernetes 本身存在的存儲、網絡、安全和易用性等痛點。除此之外，平臺已經整合并優化了多個適用于容器場景的功能模塊，以完整的解決方案幫助企業輕松應對敏捷開發與自動化運維、微服務治理、多租戶管理、工作負載和集群管理、服務與網絡管理、應用編排與管理、鏡像倉庫管理和存儲管理等業務場景。

KubeSphere安裝

先要安裝k8s

安裝網絡插件

#安裝網絡插件
vi calico.yaml
kubectl apply -f calico.yamlkubectl get pod -Awatch -n 1 kubectl get pod -Ayum install -y nfs-utils# 在master 執行以下命令 
echo "/nfs/data/ *(insecure,rw,sync,no_root_squash)" > /etc/exports# 執行以下命令，啟動 nfs 服務;創建共享目錄
mkdir -p /nfs/data# 在master執行
systemctl enable rpcbind
systemctl enable nfs-server
systemctl start rpcbind
systemctl start nfs-server# 使配置生效
exportfs -r
#檢查配置是否生效
exportfs

安裝其他插件
