Kubernetes external storage provisioner for Dell Isilon

k8s_isi_provisioner

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.

Building

To build this provisioner, ensure you have Go installed. This code requires a minimum of Go 1.11.
To build the software, run make.

Deploying

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

---

Tested against: https://www.emc.com/products-solutions/trial-software-download/isilon.htm

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.

Parameters

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

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.
