Red Hat Marketplace

The installation of StorageOS using the Red Hat Marketplace requires the Openshift cluster to be registered to the Marketplace Portal, including the roll out of the PullSecret in your cluster. Failure to do so will result in a image pull authentication failure with the Red Hat registry.

1. Select the OperatorHub from the Catalog sub menu and search for StorageOS.

   

   Choose the RedHat Marketplace option.

2. Select StorageOS and click purchase. Note that Openshift needs to be registered with the Red Hat Marketplace portal.

   

3. Select the most suitable install option.

   

   Project Edition is suitable for production workloads, Developer Edition for personal experimentation and evaluation.

4. Specify the product configuration to fit your needs.

   

5. Navigate to your software within Red Hat Marketplace and install the StorageOS software as specified in the image.

   

6. Install the Operator. Set the update approval strategy to Automatic to ensure that you always have the latest version of StorageOS installed.

   

7. The StorageOS Cluster Operator is installed into your specified cluster.

   

8. Create a Secret in the openshift-operators project

   

9. Use the YAML options to create a secret containing the apiUsername and an apiPassword key. The username and password defined in the secret will be used to authenticate when using the StorageOS CLI and GUI. For the communication between StorageOS and OpenShift, the CSI credentials csiProvisionUsername, csiProvisionPassword, csiControllerPublishUsername, csiControllerPublishPassword, csiNodePublishUsername, csiNodePublishPassword are needed. Take note of which project you created the secret in.

   Input the Secret as YAML for simplicity.

   apiVersion: v1
   kind: Secret
   metadata:
     name: storageos-api
     namespace: openshift-operators
   type: "kubernetes.io/storageos"
   data:
     # echo -n '<secret>' | base64
     apiUsername: c3RvcmFnZW9z
     apiPassword: c3RvcmFnZW9z
     # CSI Credentials
     csiProvisionUsername: c3RvcmFnZW9z
     csiProvisionPassword: c3RvcmFnZW9z
     csiControllerPublishUsername: c3RvcmFnZW9z
     csiControllerPublishPassword: c3RvcmFnZW9z
     csiNodePublishUsername: c3RvcmFnZW9z
     csiNodePublishPassword: c3RvcmFnZW9z
     csiControllerExpandUsername: c3RvcmFnZW9z
     csiControllerExpandPassword: c3RvcmFnZW9z
   

   

10. Go to StorageOS in your “Installed Operators”

    

    Verify that the StorageOS Cluster Operator is installed

11. Go to the “StorageOS Cluster” section

    

12. Create the StorageOS Cluster

    

    A StorageOS Cluster is defined using a Custom Resource Definition

13. Create the Custom Resource

    The StorageOS cluster resource describes the StorageOS cluster that will be created. Parameters such as the secretRefName, the secretRefNamespace and the kvBackend.address are mandatory.

    Additional spec parameters are available on the Cluster Operator configuration page.

    apiVersion: "storageos.com/v1"
    kind: StorageOSCluster
    metadata:
      name: storageos
      namespace: openshift-operators
    spec:
      # StorageOS Pods are in kube-system by default
      secretRefName: "storageos-api" # Reference the Secret created in the previous step
      secretRefNamespace: "openshift-operators"  # Namespace of the Secret created in the previous step
      k8sDistro: "openshift"
      kvBackend:
        address: 'storageos-etcd-client.etcd:2379' # Example address, change for your etcd endpoint
      # address: '10.42.15.23:2379,10.42.12.22:2379,10.42.13.16:2379' # You can set ETCD server ips
      resources:
        requests:
          memory: "512Mi"
          cpu: 1
      # nodeSelectorTerms:
      #   - matchExpressions:
      #     - key: "node-role.kubernetes.io/worker" # Compute node label will vary according to your installation
      #       operator: In
      #       values:
      #       - "true"
    

    

14. Verify that the StorageOS Cluster Resource enters a running state.

    

    It can take up to a minute to report the StorageOS Pods ready

15. Check the StorageOS Pods in the kube-system project

    

    A Status of 3/3 for the Daemonset Pods indicates that StorageOS is bootstrapped successfully.

16. License cluster

    A newly installed StorageOS cluster does not include a licence. A cluster must be licensed within 24 hours of the installation. For more information, check the reference licence page.

    You can apply a Free Developer licence following the operations licensing page, or purchase a licence contacting [email protected].

Manual install

The StorageOS Cluster Operator is a Kubernetes native application developed to deploy and configure StorageOS clusters, and assist with maintenance operations. We recommend its use for standard installations.

The operator is a Kubernetes controller that watches the StorageOSCluster CRD. Once the controller is ready, a StorageOS cluster definition can be created. The operator will deploy a StorageOS cluster based on the configuration specified in the cluster definition.

Helm Note: If you want to use Helm to install StorageOS, follow the StorageOS Operator Helm Chart documentation.

Steps to install StorageOS:

• Install StorageOS Operator
• Create a Secret for default username and password
• Trigger bootstrap using a CustomResource
• Apply StorageOS licence

1. Install StorageOS operator

Install the StorageOS Cluster Operator using the following yaml manifest.

oc create -f https://github.com/storageos/cluster-operator/releases/download/v2.4.4/storageos-operator.yaml

Verify the Cluster Operator Pod Status

[root@master03]# oc -n storageos-operator get pod
NAME                                         READY     STATUS    RESTARTS   AGE
storageoscluster-operator-68678798ff-f28zw   1/1       Running   0          3m

The READY 1/1 indicates that storageoscluster resources can be created.

2. Create a Secret

Before deploying a StorageOS cluster, create a Secret defining the StorageOS API Username and Password in base64 encoding. The API username and password are used to create the default StorageOS admin account which can be used with the StorageOS CLI and to login to the StorageOS GUI. The CSI credentials are used to register the CSI accounts, so Kubernetes and StorageOS communicate over an authenticated API.

apiVersion: v1
kind: Secret
metadata:
  name: "storageos-api"
  namespace: "storageos-operator"
  labels:
    app: "storageos"
type: "kubernetes.io/storageos"
data:
  # echo -n '<secret>' | base64
  apiUsername: c3RvcmFnZW9z
  apiPassword: c3RvcmFnZW9z
  # CSI Credentials
  csiProvisionUsername: c3RvcmFnZW9z
  csiProvisionPassword: c3RvcmFnZW9z
  csiControllerPublishUsername: c3RvcmFnZW9z
  csiControllerPublishPassword: c3RvcmFnZW9z
  csiNodePublishUsername: c3RvcmFnZW9z
  csiNodePublishPassword: c3RvcmFnZW9z
  csiControllerExpandUsername: c3RvcmFnZW9z
  csiControllerExpandPassword: c3RvcmFnZW9z

This example contains a default password, for production installations, use a unique, strong password.

You can define a base64 value by echo -n "mystring" | base64.

Make sure that the encoding of the credentials doesn’t have special characters such as ‘\n’. The echo -n ensures that a trailing new line is not appended to the string.

If you wish to change the default accounts details post-install please see Managing Users

3 Trigger a StorageOS installation

This is a Cluster Definition example.

apiVersion: "storageos.com/v1"
kind: StorageOSCluster
metadata:
  name: "example-storageos"
  namespace: "storageos-operator"
spec:
  secretRefName: "storageos-api" # Reference from the Secret created in the previous step
  secretRefNamespace: "storageos-operator"  # Namespace of the Secret
  k8sDistro: "openshift"
  images:
    nodeContainer: "storageos/node:v2.4.4" # StorageOS version
  kvBackend:
    address: 'storageos-etcd-client.storageos-etcd:2379' # Example address, change for your etcd endpoint
  # address: '10.42.15.23:2379,10.42.12.22:2379,10.42.13.16:2379' # You can set ETCD server ips
  resources:
    requests:
      memory: "512Mi"
      cpu: 1
#  nodeSelectorTerms:
#    - matchExpressions:
#      - key: "node-role.kubernetes.io/worker" # Compute node label will vary according to your installation
#        operator: In
#        values:
#        - "true"

Additional spec parameters are available on the Cluster Operator configuration page.

You can find more examples such as deployments referencing a external etcd kv store for StorageOS in the Cluster Operator examples page.

Verify StorageOS Installation

[root@master03]# oc -n kube-system get pods -w
NAME                                    READY   STATUS    RESTARTS   AGE
storageos-csi-helper-5cf59b5b4-f5nwr    2/2     Running   0          3m
storageos-daemonset-75f6c               3/3     Running   0          3m
storageos-daemonset-czbqx               3/3     Running   0          3m
storageos-daemonset-zv4tq               3/3     Running   0          3m
storageos-scheduler-6d67b46f67-5c46j    1/1     Running   0          3m

The above command watches the Pods created by the Cluster Definition example. Note that pods typically take approximately 65 seconds to enter the Running Phase.

4. License cluster

Newly installed StorageOS clusters must be licensed within 24 hours. Our developer license is free, and supports up to 5TiB of provisioned storage.

To obtain a license, follow the instructions on our licensing operations page.
