## 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](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:
|
||
|
|
|
||
|
|
```console
|
||
|
|
kubectl create -f ./your_new_pod.json
|
||
|
|
```
|
||
|
|
|
||
|
|
Here is my command and output:
|
||
|
|
|
||
|
|
```console
|
||
|
|
# 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
|
||
|
|
|
||
|
|
```console
|
||
|
|
#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.
|
||
|
|
|
||
|
|
```console
|
||
|
|
# docker ps
|
||
|
