Loading a sample file, sample.json, requires some setup

at the volume level.

If you have an NFS file system, you can create a PV

of type nfs, then create a PVC that specifically mounts

that persistent volume, then copy your sample data into

that location.

Lets assume your NFS mount is at /nfsfileshare on host 192.168.0.107, you can

create a PV as follows:

You then copy your sample data into that PV:

cp sample.json /nfsfileshare

You then create the PVC, csv-pvc, which is referenced by

the sample load configuration.

We test with storageos and it offers a RWO storage class

that can be used for volume provisioning.

To accomplish this, download the storageos CLI from their github site.

To prepare a volume with sample load data, you do the following

for storageos:

Create the PVC that will create a blank storageos volume

for us to use:

kubectl create -f csv-pvc-sc.yaml

Next, locate the storageos Kube IP address:

kubectl get svc -n storgeos

As root, set up the storageos environment variables required by the

storageos CLI:

export KUBECONFIG=/etc/kubernetes/admin.conf

export STORAGEOS_HOST=10.101.214.130

export STORAGEOS_PASSWORD=storageos STORAGEOS_USERNAME=storageos

storageos volume ls

Locate the volume path/name from the above volume listing, then use

that path in a mount command:

storageos volume mount pgouser1/pvc-3c7491f5-5b9e-11e9-a4a4-52540030262d /mnt

The above command mounts the storageos volume into /mnt on your local

linux host where you can now access it using normal linux commands.

Next, you copy the sample data file into the storageos volume

which is mounted on your linux host at /mnt:

sudo cp sample.json /mnt

Unmount the volume so that it can be mounted by the load job:

storageos volume unmount pgouser1/pvc-3c7491f5-5b9e-11e9-a4a4-52540030262d

At this point, you have a storageos backed PVC, csv-pvc, that has

the sample.json file loaded into it and its ready to be used

by the load job. One last change is required to mount the storageos

volume within the Operator load job, that is to add a SecurityContext

to the load job configuration:

SecurityContext: "securityContext":{"fsGroup":26},
