fortress-csi

The Container Storage Interface (CSI) Driver for Fortress Block Storage This driver allows you to use Fortress Block Storage with your container orchestrator.

More information about the CSI and Kubernetes can be found: CSI Spec and Kubernetes CSI

Installation

Requirements

• --allow-privileged must be enabled for the API server and kubelet

Kubernetes secret

In order for the csi to work properly, you will need to deploy a kubernetes secret. To obtain a API key

The secret.yml definition is as follows.

apiVersion: v1
kind: Secret
metadata:
  name: fortress-csi
  namespace: kube-system
stringData:
  # Replace the api-key with a proper value
  api-key: "FORTRESS_API_KEY"

To create this secret.yml, you must run the following

$ kubectl create -f secret.yml            
secret/fortress-csi created

Deploying the CSI

To deploy the latest release of the CSI to your Kubernetes cluster, run the following:

kubectl apply -f https://raw.githubusercontent.com/mrjosh/fortress-csi/develop/chart/fortress.yaml

Validating

The deployment will create a Storage Class which will be used to create your volumes

$ kubectl get storageclass
NAME                               PROVISIONER             RECLAIMPOLICY   VOLUMEBINDINGMODE      ALLOWVOLUMEEXPANSION   AGE
fortress-block-storage (default)   fortress                Delete          Immediate              false                  119m

To further validate the CSI, create a PersistentVolumeClaim

apiVersion: v1
kind: PersistentVolumeClaim
metadata:
  name: csi-pvc
spec:
  accessModes:
  - ReadWriteOnce
  resources:
    requests:
      storage: 1Gi
  storageClassName: fortress-block-storage

Now, take the yaml shown above and create a pvc.yml and run:

kubectl create -f pvc.yml

You can see that you have a PersistentVolume created by your Claim

$ kubectl get pv
NAME                   CAPACITY   ACCESS MODES   RECLAIM POLICY   STATUS     CLAIM             STORAGECLASS             REASON   AGE
pvc-0d87f99b8d5f4419   1Gi        RWO            Delete           Bound      default/csi-pvc   fortress-block-storage            118m
