iSCSI SharedFS dynamic provisioner

Image	Build Status
iscsi-sharedfs-provisioner

Runs as deployment.

Waits until PersistentVolumeClaims will be created in Kubernetes.

Then creates new drives with needed parameters and announce them as PersistentVolume in Kubernetes.

Usage

• Create service account and cluster role for your provisioner:

  kubectl apply -f https://raw.githubusercontent.com/kvaps/kube-iscsi-loop/master/iscsi-sharedfs-provisioner/serviceaccount.yaml

• Download example yaml for deployment and update it for passthrough your filesystem to both containers. Check configuration variables section below.

  curl -o iscsi-sharedfs-provisioner.yaml -L https://raw.githubusercontent.com/kvaps/kube-iscsi-loop/master/iscsi-sharedfs-provisioner/iscsi-sharedfs-provisioner.yaml
  vim iscsi-sharedfs-provisioner.yaml
  kubectl apply -f iscsi-sharedfs-provisioner.yaml

  In this example we are presume that your filesystem is mounted on /stor/sharedfs on every node

  better to passthrough upper directory (/stor) with your filesystem mountpoint for make possible mountpoint chek

  WARNING

  If you use kubernetes < 1.10 version, you need to enable mountPropagation in featuregates.

• Check storageclass options section below, then create new storage class with your filesystem:

  curl -o class.yaml -L https://raw.githubusercontent.com/kvaps/kube-iscsi-loop/master/iscsi-sharedfs-provisioner/class.yaml
  vim class.yaml
  kubectl apply -f class.yaml

• Create example claim and example pod

  kubectl apply -f https://raw.githubusercontent.com/kvaps/kube-iscsi-loop/master/iscsi-sharedfs-provisioner/claim.yaml
  kubectl apply -f https://raw.githubusercontent.com/kvaps/kube-iscsi-loop/master/iscsi-sharedfs-provisioner/test-pod.yaml

Configuration variables

• PROVISIONER_NAME - Your provisioner identificator (default: kvaps/sharedfs)

Storageclass options

• iqn - iqn for clients, it should be same like IQN variable for iscsi-sharedfs-publisher image (example: iqn.2018-09.org.loopback.sharedfs)
• lun - lun number, it should be same like LUN variable for iscsi-sharedfs-publisher image (default: 1)
• mmpUpdateInterval - set interval for enable multimount protection for filesystem. (example: 5)
• mountpoint - Mountpoint for your filesystem (example: /stor/sharedfs)
• directory - relative path for images storage directory (example images)
