最小化安装Kubesphere报错问题解决方法

最小化安装Kubesphere报错:

TASK [preinstall : Stop if defaultStorageClass was not found] ******************
fatal: [localhost]: FAILED! => {"assertion": "\"(default)\" in default_storage_class_check.stdout", "changed": false, "evaluated_to": false, "msg": "Default StorageClass was not found !"
}

解决方法：

删除 kubesphere 组件重装：

[root@k8snode1 ~]# kubectl get deploy -n kubesphere-system
NAME           READY   UP-TO-DATE   AVAILABLE   AGE
ks-installer   1/1     1            1           12m
[root@k8snode1 ~]# kubectl delete deploy ks-installer -n kubesphere-system
deployment.extensions "ks-installer" deleted
[root@k8snode1 ~]#

注：多试几次可以解决这个报错。
安装 kubesphere 的时候要确保 master 节点没有 Taint。参考：https://v2-1.docs.kubesphere.io/docs/zh-CN/appendix/install-openebs/

确认 master 节点是否有 Taint，如下看到 master 节点有 Taint。

$ kubectl describe node master | grep Taint
Taints:             node-role.kubernetes.io/master:NoSchedule

去掉 master 节点的 Taint：

$ kubectl taint nodes master node-role.kubernetes.io/master:NoSchedule-

重装：

[root@k8snode1 ~]# kubectl apply -f kubesphere-mini.yaml 
namespace/kubesphere-system unchanged
configmap/ks-installer unchanged

重装 kubesphere 遇到第二个报错：

忘记把错误日志记录下来了。。。

[root@k8snode1 ~]# kubectl get deploy -n kubesphere-system
NAME           READY   UP-TO-DATE   AVAILABLE   AGE
ks-installer   1/1     1            1           12m
redis          0/1     1            0           10m
[root@k8snode1 ~]#

解决方法：
还是删除 kubesphere 组件，再次重装：

[root@k8snode1 ~]# kubectl delete deploy ks-installer -n kubesphere-system
deployment.extensions "ks-installer" deleted
[root@k8snode1 ~]# 
[root@k8snode1 ~]# kubectl delete deploy redis -n kubesphere-system
deployment.extensions "redis" deleted
[root@k8snode1 ~]#

注：安装 kubesphere 的时候要确保 master 节点没有 Taint。参考：https://v2-1.docs.kubesphere.io/docs/zh-CN/appendix/install-openebs/

重装：

[root@k8snode1 ~]# kubectl apply -f kubesphere-mini.yaml
