Usage

Deploy KaDalu Operator on an already running Kubernetes cluster using,

kubectl create -f https://raw.githubusercontent.com/kadalu/kadalu/master/manifests/kadalu-operator-0.3.0.yaml

Use kadalu-operator-openshift-0.3.0.yaml in case of Openshift.

oc create -f https://raw.githubusercontent.com/kadalu/kadalu/master/manifests/kadalu-operator-openshift-0.3.0.yaml

KaDalu Operator listens to Storage setup configuration changes and starts the required pods. For example,

# File: storage-config.yaml
---
apiVersion: kadalu-operator.storage/v1alpha1
kind: KadaluStorage
metadata:
  # This will be used as the name of PV Hosting Volume
  name: storage-pool-1
spec:
  type: Replica1
  storage:
    - node: kube1      # node name as shown in `kubectl get nodes`
      device: /dev/vdc # Device to provide storage to all PVs

Now request kadalu-operator to setup storage using,

$ kubectl create -f storage-config.yaml

Operator will start the storage export pods as required. And, in 2 steps, your storage system is up and running.

Check the status of Pods using,

$ kubectl get pods -nkadalu
