Step 1. Setting up Fibre Channel Target

On your FC SAN Zone manager, allocate and mask LUNs so Kubernetes hosts can access them.

Step 2. Creating the Pod with Fibre Channel persistent storage

Once you have installed Fibre Channel initiator and new Kubernetes, you can create a pod based on my example fc.yaml. In the pod JSON, you need to provide targetWWNs (array of Fibre Channel target's World Wide Names), lun, and the type of the filesystem that has been created on the lun, and readOnly boolean.

Once your pod is created, run it on the Kubernetes master:

kubectl create -f ./your_new_pod.json

Here is my command and output:

# kubectl create -f examples/volumes/fibre_channel/fc.yaml
# kubectl get pods
NAME      READY     STATUS    RESTARTS   AGE
fcpd      2/2       Running   0          10m

On the Kubernetes host, I got these in mount output

#mount |grep /var/lib/kubelet/plugins/kubernetes.io
/dev/mapper/360a98000324669436c2b45666c567946 on /var/lib/kubelet/plugins/kubernetes.io/fc/500a0982991b8dc5-lun-2 type ext4 (ro,relatime,seclabel,stripe=16,data=ordered)
/dev/mapper/360a98000324669436c2b45666c567944 on /var/lib/kubelet/plugins/kubernetes.io/fc/500a0982991b8dc5-lun-1 type ext4 (rw,relatime,seclabel,stripe=16,data=ordered)

If you ssh to that machine, you can run docker ps to see the actual pod.

# docker ps
