Kubernetes external storage provisioner for Dell Isilon
Based on the following:
- https://github.com/kubernetes-sigs/sig-storage-lib-external-provisioner
- https://github.com/tenortim/goisilon
Instructions: In order to use this external provisioner, you can use the image pushed to docker hub "tenortim/k8s_isi_provisioner", or build it yourself.
To build this provisioner, ensure you have Go installed.
This code requires a minimum of Go 1.11.
To build the software, run make.
The provisioner requires various permissions whether you are running it in raw Kubernetes or in OpenShift. The persistent-volume-provisioner cluster role in OpenShift 3.11 is missing the needed endpoints permissions and so permissions are supplied by auth.yaml for both OpenShift and pure Kubernetes:
oc create -f auth.yaml
or
kubectl create -f auth.yaml
To deploy the provisioner, run
oc create -f pod.yaml
or
kubectl create -f pod.yaml
If you need to create exports in an access zone other than the System zone, set the ISI_ZONE environment variable in pod.yaml.
Create the isilon storage class using the class.yaml file
oc create -f class.yaml
or
kubectl create -f class.yaml
Note, the NFS mount options that the pod will use are specified at the time that the storage class is created. If additional volume mount options (e.g. forcing NFS version 3) are needed, they can be specified in the class file:
oc create -f class-with-mount-options.yaml
or
kubectl create -f class-with-mount-options.yaml
Example code to create a persistent volume claim named isilon-pvc:
oc create -f claim.yaml
or
kubectl create -f claim.yaml

This provisioner has support for Isilon Storage Quotas. When enabled, hard, enforcing directory quotas will be created based on the requested size of the volume. The container flag is not currently set so the reported size from 'df' will not reflect the limit, but it will be enforced. This will a require a revision of the goisilon library to support the functionality.
| Param | Description | Example |
|---|---|---|
| ISI_SERVER | The DNS name (or IP address) of the Isilon to use for mount requests | isilon.somedomain.com |
| ISI_API_SERVER | The DNS name (or IP address) of the Isilon to use for API access to create the volume (defaults to ISI_SERVER) | isilon-mgmt.somedomain.com |
| ISI_PATH | The root path for all exports to be created in | /ifs/ose_exports |
| ISI_ZONE | The access zone for all exports to be created in (defaults to System) | System |
| ISI_USER | The user to connect to the isilon as | admin |
| ISI_PASS | Password for the user account | password |
| ISI_GROUP | The default group to assign to the share | users |
| ISI_QUOTA_ENABLE | Enable the use of quotas. Defaults to disabled. | FALSE or TRUE |
| PROVISIONER_NAME | Alternate name to allow registering multiple providers with different parameters. Defaults to "isilon" | isilon |
Thanks to the developers of the Kubernetes external storage provisioner code and the docs that are making this possible to do. Thanks to Dell EMC {code} for the great Isilon library.
