== Overview ==
If you have a Data Management Plan (DMP), or you have access to a custom CIFS (SMB, Samba, Windows Share) storage you want to mount in a pod please follow the steps below
== Convert your credentials to base64 encoding ==
In a terminal type:
<syntaxhighlight lang="bash">
echo -n "<Your_CIFS_Username>" | base64
$ PFlvdXJfQ0lGU19Vc2VybmFtZT4=
echo -n "<Your_CIFS_Password" | base64
$ PFlvdXJfQ0lGU19QYXNzd29yZA==
</syntaxhighlight>
Note that the output shown here is literally for the example used
== Create a secret containing your credentials to the storage ==
Having your credentials encoded in base 64, you can create a cifs_secret.yaml like shown below:
<syntaxhighlight lang="bash">
apiVersion: v1
kind: Secret
metadata:
name: cifs-secret
namespace: user-<your-username>
type: fstab/cifs
data:
username: 'PFlvdXJfQ0lGU19Vc2VybmFtZT4='
password: 'PFlvdXJfQ0lGU19QYXNzd29yZA=='
</syntaxhighlight>
You can then type:
<syntaxhighlight lang="bash">
kubectl create secret -f secret.yaml
</syntaxhighlight>
== Adding your mounting option in your pod ==
Reusing our standard example of pod, we have to modify the section volumeMounts and Volumes in our pod creation file:
<syntaxhighlight lang="bash">
apiVersion: v1
kind: Pod
metadata:
name: busybox-test-pod
spec:
containers:
- name: busybox
