MOOSE-CSI-PLUGIN

Test cluster servers:


k8s87	192.168.2.87	centos7.9-2009
k8s89	192.168.2.89	centos7.9-2009
k8s90	192.168.2.90	centos7.9-2009

k8s version : v1.25.3 (latest version) moosefs (standalone): maintained in k8s90, v 3.0.116

1. First step:

download files , edited the kustomization.yaml file , change MFS_SERVER option to my moosefs master ip 192.168.2.90 , make direcotory /kubernetes in moosefs for k8s

2. Next step:

install moosefs-csi plugin

pod/csi-moosefs-controll pod/csi-moosefs-node are running

(base) [root@k8s87 kubernetes]# kubectl get pod --all-namespaces

......

3. Next Step:

apply examples (pv ,pvc pod)

kubectl apply -f moosefs-csi-example-pv.yaml
kubectl apply -f moosefs-csi-example-pvc.yaml

(base) [root@k8s87 examples]# kubectl get pv,pvc -n default

(base) [root@k8s87 kubernetes]# kubectl get pod --all-namespaces

......

apply example pods something wrong

kubectl apply -f moosefs-csi-example-pod.yaml

(base) [root@k8s87 kubernetes]# kubectl get pod --all-namespaces

4. Questions

Question 1: moose-csi-driverinfo.yaml errors in k8s 1.25.x

something wrong when invoke "kustomize build | kubectl apply -f -".

error: resource mapping not found for name: "csi.kunde21.moosefs" namespace: "" from "STDIN": no matches for kind "CSIDriver" in version "storage.k8s.io/v1beta1" resolution: edit moosefs-csi-driverinfo.yaml line 2, change to to storage.k8s.io/v1. It's easy

Question 2: moose-exmample-pod.yaml Attach PV(PVC) failed

May I miss steps or something else to success?

something wrong when apply example pod in k8s v1.25.x #17
