Once you have installed iSCSI initiator and new Kubernetes, you can create a pod based on my example *iscsi.json*. In the pod JSON, you need to provide *targetPortal* (the iSCSI target's **IP** address and *port* if not the default port 3260), target's *iqn*, *lun*, and the type of the filesystem that has been created on the lun, and *readOnly* boolean.

**Note:** If you have followed the instructions in the links above you
may have partitioned the device, the iSCSI volume plugin does not
currently support partitions so format the device as one partition.
Make sure you have the correct device name then run the following as

```console
mkfs.ext4 /dev/<name of device>
```
Once your pod is created, run it on the Kubernetes master: Once your pod is created, run it on the Kubernetes master:
