kubesphere的安装部署

书接上回，本周把kubesphere的安装部署记录发出来，

首先要安装部署storageclass，

需要在每个node上安装nfs客户端软件，sudo apt install nfs-common，

然后下载storageclass的安装部署yaml模板，

wget https://raw.githubusercontent.com/kubernetes-incubator/external-storage/master/nfs-client/deploy/class.yaml，

wget https://raw.githubusercontent.com/kubernetes-incubator/external-storage/master/nfs-client/deploy/deployment.yaml，

wget https://raw.githubusercontent.com/kubernetes-incubator/external-storage/master/nfs-client/deploy/rbac.yaml，

接着执行yaml模板，kubectl apply -f rbac.yaml，

执行deployment模板之前要改一下配置，

vim deployment.yaml

         env:

           - name: PROVISIONER_NAME

             value: fuseim.pri/ifs

           - name: NFS_SERVER

             value: 10.90.11.161

           - name: NFS_PATH

             value: /mnt/truenas

     volumes:

       - name: nfs-client-root

         nfs:

           server: 10.90.11.161

           path: /mnt/truenas

kubectl apply -f deployment.yaml，kubectl apply -f class.yaml，

查看部署成功的storageclass，kubectl get storageclass，

把当前的storageclass设置成default，这个很重要，不然后面部署kubesphere的时候会报错，

kubectl patch storageclass managed-nfs-storage -p '{"metadata": {"annotations":{"storageclass.kubernetes.io/is-default-class":"true"}}}'，

接下来就是真正部署kubesphere了，

下载kubesphere的安装部署yaml模板，

wget https://github.com/kubesphere/ks-installer/releases/download/v3.1.1/kubesphere-installer.yaml，

wget https://github.com/kubesphere/ks-installer/releases/download/v3.1.1/cluster-configuration.yaml，

执行yaml模板，kubectl apply -f kubesphere-installer.yaml，

kubectl apply -f cluster-configuration.yaml，

通过下面命令查看部署的进度，

kubectl logs -n kubesphere-system $(kubectl get pod -n kubesphere-system -l app=ks-install -o jsonpath='{.items[0].metadata.name}') -f，

部署成功的输出是下面这样，

按照提示访问管理界面，

界面很清爽，下周再把rancher也装上对比一下。
