Feature Status

Alpha

Compiling and Package

nasplugin.csi.alibabacloud.com can be compiled in a form of a container.

To build a container:

$ cd build && sh build-nas.sh

Usage

Prerequisite

Same as diskplugin.csi.alibabacloud.com;

Step 1: Create CSI Plugin

# kubectl create -f ./deploy/nas/nas-plugin.yaml

Note: The plugin log style can be configured by environment variable: LOG_TYPE.

"host": logs will be printed into files which save to host(/var/log/alicloud/nasplugin.csi.alibabacloud.com.log);

"stdout": logs will be printed to stdout, can be printed by docker logs or kubectl logs.

"both": default option, log will be printed both to stdout and host file.

Step 2: Create nginx deploy with csi

# kubectl create -f ./examples/nas/deploy.yaml

Step 3: Check status of PVC/PV

# kubectl get pvc
NAME      STATUS    VOLUME       CAPACITY   ACCESS MODES   STORAGECLASS   AGE
nas-pvc   Bound     nas-csi-pv   5Gi        RWO                           3m

# kubectl get pv
NAME                                       CAPACITY   ACCESS MODES   RECLAIM POLICY   STATUS        CLAIM              STORAGECLASS   REASON    AGE
