基于现有storageClass_yaml文件添加新的sc
方法
导出现有sc.yaml,改名，删除不必要项，apply，kg sc验证
步骤
1.查看现有sc
需要一个新rbd_sc，名字叫csi-rbd-sc，拷贝rook-ceph-block的yaml，删改后apply
# kg sc
NAME PROVISIONER RECLAIMPOLICY VOLUMEBINDINGMODE ALLOWVOLUMEEXPANSION AGE
rook-ceph-block rook-ceph.rbd.csi.ceph.com Delete Immediate true 23h
rook-cephfs rook-ceph.cephfs.csi.ceph.com Delete Immediate true 23h
2.导出yaml
time,resource字段删掉，名字改掉就可以
# kg sc rook-ceph-block -o yaml >rook-ceph-block.yaml
time: "2021-12-30T06:50:04Z"
name: igo-rbd
resourceVersion: "52083"
3.k apply -f igo-rbd.yaml
4.验证
# kg sc
NAME PROVISIONER RECLAIMPOLICY VOLUMEBINDINGMODE ALLOWVOLUMEEXPANSION AGE
igo-rbd rook-ceph.rbd.csi.ceph.com Delete Immediate true 6m5s
rook-ceph-block rook-ceph.rbd.csi.ceph.com Delete Immediate true 24h
rook-cephfs rook-ceph.cephfs.csi.ceph.com Delete Immediate true 24h
tips
建议k9s edit 得到的yaml比较干净直观，保存修改一样可以使用
