## Step 1. Setting up iSCSI target and iSCSI initiator
I use Fedora 21 on Kubernetes node. First install iSCSI initiator on the node:
**Setup A.** On Fedora 21 nodes
If you use Fedora 21 on Kubernetes node, then first install iSCSI initiator on the node:
# yum -y install iscsi-initiator-utils

I mostly followed these [instructions](http://www.server-world.info/en/note?os=Fedora_21&p=iscsi&f=2) to setup iSCSI initiator and these [instructions](http://www.server-world.info/en/note?os=Fedora_21&p=iscsi) to setup iSCSI target.
[Here](https://github.com/caesarxuchao/iscsiOnGCE) is an alternative setup on GCE.
**Setup B.** On Unbuntu 12.04 and Debian 7 nodes on GCE
GCE does not provide preconfigured Fedora 21 image, so I set up the iSCSI target on a preconfigured Ubuntu 12.04 image, mostly following these [instructions](http://www.server-world.info/en/note?os=Ubuntu_12.04&p=iscsi). My Kubernetes cluster on GCE was running Debian 7 images, so I followed these [instructions](http://www.server-world.info/en/note?os=Debian_7.0&p=iscsi&f=2) to set up the iSCSI initiator.
##Step 2. Creating the pod with iSCSI persistent storage
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.
