IBM Cloud Object Storage Driver

IBM Cloud Object Storage Driver

You can use the IBM Cloud Object Storage driver template to create and access data in multiple s3 storage providers such as IBM, AWS, Wasabi, Azure, and more. Review the following steps to deploy the IBM Cloud Object Storage driver to your Satellite clusters.

Before you can deploy storage templates to clusters in your location, make sure you set up Satellite Config by selecting the Enable cluster admin access for Satellite Config option in the console or including the --enable-config-admin option when you create your cluster.

You cannot scope Satellite storage service to resource groups. However, if you are scoping other resources such as location and cluster to resource groups, you need to add Satellite reader and link administrator role for all resources in the account.

Prerequisites

  1. Create a Satellite location.

  2. Create a set of service credentials in your object storage provider.

  3. Create a secret that contains your s3 credentials.

Creating a secret in your cluster that contains your object storage credentials

Create the Kubernetes secret in your cluster that contains your service credentials.

  1. Follow the steps based on your object storage provider to create a secret in your cluster. When you create your secret, all values are automatically encoded to base64. In the following example, the secret name is cos-write-access.

    • IBM Cloud Object Storage

      1. Find your service instance ID.

        ibmcloud resource service-instance <service_name> | grep GUID
        
      2. Create the secret in your cluster.

        oc create secret generic cos-write-access --type=ibm/ibmc-s3fs --from-literal=api-key=API-KEY --from-literal=service-instance-id=SERVICE-INSTANCE-ID
        
    • AWS or Wasabi

      oc create secret generic cos-write-access --type=ibm/ibmc-s3fs --from-literal=access-key=ACCESS-KEY-ID --from-literal=secret-key=SECRET-ACCESS-KEY
      

Creating and assigning a configuration in the console

  1. Review the parameter reference.

  2. From the Locations console, select the location where you want to create a storage configuration.

  3. Select Storage > Create storage configuration

  4. Enter a name for your configuration.

  5. Select the Storage type.

  6. Select the Version and click Next

  7. If the Storage type that you selected accepts custom parameters, enter them on the Parameters tab.

  8. If the Storage type that you selected requires secrets, enter them on the Secrets tab.

  9. On the Storage classes tab, review the storage classes that are deployed by the configuration or create a custom storage class.

  10. On the Assign to service tab, select the service that you want to assign your configuration to.

  11. Click Complete to assign your storage configuration.

Creating a configuration in the CLI

  4. Target the Managed from region of your Satellite location. For example, for wdc target us-east. For more information, see Satellite regions.

    ibmcloud target -r us-east
    
  5. If you use a resource group other than default, target it.

    ibmcloud target -g <resource-group>
    
  6. Copy one of the following example command for the template version that you want to use. For more information about the command, see ibmcloud sat storage config create in the command reference.

Creating an assignment in the CLI

  1. List your storage configurations and make a note of the storage configuration that you want to assign to your clusters.

    ibmcloud sat storage config ls
    
  2. Get the ID of the cluster, cluster group, or service that you want to assign storage to.

Upgrading a configuration and assignments in the API

You can use the /v2/storage/satellite/updateAssignment API to update your assignments with new clusters or cluster groups. Set updateConfigVersion to true to apply the revision update.

  1. Copy the following example request and replace the variables for the cluster groups and assignments that you want to update.

    curl -X PATCH "https://containers.cloud.ibm.com/global/v2/storage/satellite/updateAssignment" -H "accept: application/json" -H "Authorization: Bearer TOKEN" -H "Content-Type: application/json" -d "{ \"groups\": [ \"CLUSTER-GROUPS\" ], \"name\": \"ASSIGNMENT-NAME\", \"updateConfigVersion\": true, \"uuid\": \"ASSIGNMENT-ID\"}"

Enabling automatic patch updates for assignments in the API

You can use the /v2/storage/satellite/setAssignmentAutoupgrade API to enable automatic patch updates for your assignments. Enabling automatic patch updates applies the latest storage template revisions (patches) automatically. You must still apply major updates manually.

  1. Copy the following example request and replace the variables for the cluster groups and assignments that you want to update.

    curl -X PATCH "https://containers.cloud.ibm.com/global/v2/storage/satellite/setAssignmentAutoupgrade" -H "accept: application/json" -H "Authorization: Bearer TOKEN" -H "Content-Type: application/json" -d { "config": "string", "controller": "string", "autopatch": boolean,"assignment" : { "all": boolean, "uuid": ["string", "string", ...], } }
    
  2. Run the request.

  3. Get the details of you assignment to verify the upgrade.

    curl -X GET "https://containers.cloud.ibm.com/global/v2/storage/satellite/getAssignment?uuid=ASSIGNMENT-ID" -H "accept: application/json" -H "Authorization: Bearer TOKEN"
    

Deploying an app that uses IBM Cloud Object Storage

You can use the ibm-object-s3fs driver to create PVCs that you can use in your cluster workloads.

  1. Create a PVC that references your object storage configuration.

    kind: PersistentVolumeClaim
    apiVersion: v1
    metadata: 
      name: demo #Enter a name for your PVC.
      namespace: default
      annotations: 
      ibm.io/auto-create-bucket: "false"
      ibm.io/auto-delete-bucket: "false" 
      ibm.io/bucket: BUCKET-NAME #Enter the name of your object storage bucket.
      ibm.io/secret-name: SECRET-NAME #Enter the name of the secret you created earlier.
      ibm.io/secret-namespace: NAMESPACE #Enter the namespace where you want to create the PVC.
    spec: 
        accessModes:
        - ReadWriteOnce
        resources:
            requests:
                storage: 10Gi
        storageClassName: ibmc-s3fs-cos #The storage class that you want to use.
    
  2. Create the PVC in your cluster.

    oc apply -f pvc-cos.yaml
    
  3. Create a YAML configuration file for a pod that mounts the PVC that you create.

    apiVersion: v1
    kind: Pod
    metadata:
      name: demo-pod
      namespace: default
    spec:
      securityContext:
        runAsUser: 2000
        fsGroup: 2000
      volumes:
      - name: demo-vol
        persistentVolumeClaim:
            claimName: demo
      containers:
      - name: test
        image: nginxinc/nginx-unprivileged
        imagePullPolicy: Always
        volumeMounts:
        - name: demo-vol
          mountPath: /mnt/cosvol
    
  4. Create the pod in your cluster.

    oc apply -f demo-pod.yaml
    
  5. Verify that the pod is deployed. Note that it might take a few minutes for your app to get into a Running state.

    oc get pods
    
    NAME                                READY   STATUS    RESTARTS   AGE
    demo-pod                            1/1     Running   0          2m58s
    
  6. Verify that the app can write to your block storage volume by logging in to your pod.

    oc exec demo-pod -- bash -c "touch /mnt/cosvol/test.txt && ls /mnt/cosvol" test.txt
    

Removing the IBM Cloud Object Storage storage configuration using the console

  2. Select Actions > Delete
  3. Enter the name of your storage configuration.
  4. Select Delete.

Removing the IBM Cloud Object Storage storage configuration using the command line

If you no longer need your IBM Cloud Object Storage configuration, you can remove your apps, PVCs, PVs, and assignment from your clusters.

  1. List your storage assignments and find the one that you used for your cluster.

    ibmcloud sat storage assignment ls (--cluster CLUSTER | --config CONFIG | --location LOCATION | --service-cluster-id CLUSTER)
    
  2. Remove the assignment. After the assignment is removed, the driver pods and storage classes are removed from all clusters that were part of the storage assignment.
