install kubesphere on k8s

原来在gke上面装过很顺利，后面自己kubeadm安装的cluster再安装遇到了一些问题，记录下

步骤

按照官方文档安装就可以了，但是自己这里kubectl get svc/ks-console -n kubesphere-system看不到资源，日志也有报错：Stop if StorageClass was not found。gke环境sc这些默认都给配置好了，自己搭的环境就需要自己折腾了

参考这个链接，里面有处理方式，就是手动加了sc，但这样并不能解决对于我遇到的情况。

我用的rook作为存储插件，手动加sc可以参考：

[root@master ~]# cat sc.yaml
apiVersion: ceph.rook.io/v1beta1
kind: Pool
metadata:
  name: replicapool
  namespace: rook-ceph
spec:
  replicated:
    size: 3
---
apiVersion: storage.k8s.io/v1
kind: StorageClass
metadata:
  name: block-service
provisioner: ceph.rook.io/block
parameters:
  pool: replicapool
  #The value of "clusterNamespace" MUST be the same as the one in which your rook cluster exist
  #  clusterNamespace: rook-ceph

gce下可以参考这个：

apiVersion: storage.k8s.io/v1
kind: StorageClass
metadata:
  name: gce-sc
provisioner: kubernetes.io/gce-pd
parameters:
  type: pd-ssd

另外还需要设置一个default的sc:

1	kubectl patch storageclass gce-sc -p '{"metadata": {"annotations":{"storageclass.kubernetes.io/is-default-class":"true"}}}'

具体参考这里Change the default StorageClass

最后如下：

3

[root@master ~]# kubectl get sc --all-namespaces
NAME               PROVISIONER            RECLAIMPOLICY   VOLUMEBINDINGMODE   ALLOWVOLUMEEXPANSION   AGE
gce-sc (default)   kubernetes.io/gce-pd   Delete          Immediate           false                  47h

重新安装下kubesphere就ok.
