Managing hybrid and multicloud resources

Procedure

1. Click Operators → Installed Operators from the left pane of the OpenShift Web Console to view the installed operators.
2. Click OpenShift Container Storage Operator.
3. On the OpenShift Container Storage Operator page, scroll right and click the Backing Store tab.

4. Click Create Backing Store.

   Figure 4.1. Create Backing Store page

   

5. On the Create New Backing Store page, perform the following:

   1. Enter a Backing Store Name.
   2. Select a Provider.
   3. Select a Region.
   4. Enter an Endpoint. This is optional.

   5. Select a Secret from drop down list, or create your own secret. Optionally, you can Switch to Credentials view which lets you fill in the required secrets.

      For more information on creating an OCP secret, see the section Creating the secret in the Openshift Container Platform documentation.

      Each backingstore requires a different secret. For more information on creating the secret for a particular backingstore, see the Section 4.2, “Adding storage resources for hybrid or Multicloud using the MCG command line interface” and follow the procedure for the addition of storage resources using a YAML.

      Note

      This menu is relevant for all providers except Google Cloud and local PVC.

   6. Enter Target bucket. The target bucket is a container storage that is hosted on the remote cloud service. It allows you to create a connection that tells MCG that it can use this bucket for the system.
6. Click Create Backing Store.

Verification steps

1. Click Operators → Installed Operators.
2. Click OpenShift Container Storage Operator.
3. Search for the new backing store or click Backing Store tab to view all the backing stores.

Procedure

1. From the Multicloud Object Gateway (MCG) command-line interface, run the following NooBaa command:

   noobaa backingstore create s3-compatible rgw-resource --access-key=<RGW ACCESS KEY> --secret-key=<RGW SECRET KEY> --target-bucket=<bucket-name> --endpoint=<RGW endpoint>

   1. To get the <RGW ACCESS KEY> and <RGW SECRET KEY>, run the following command using your RGW user secret name:

      oc get secret <RGW USER SECRET NAME> -o yaml -n openshift-storage

   2. Decode the access key ID and the access key from Base64 and keep them.
   3. Replace <RGW USER ACCESS KEY> and <RGW USER SECRET ACCESS KEY> with the appropriate, decoded data from the previous step.
   4. Replace <bucket-name> with an existing RGW bucket name. This argument tells Multicloud Object Gateway which bucket to use as a target bucket for its backing store, and subsequently, data storage and administration.

   5. To get the <RGW endpoint>, see Accessing the RADOS Object Gateway S3 endpoint.

      The output will be similar to the following:

      INFO[0001] ✅ Exists: NooBaa "noobaa"
      INFO[0002] ✅ Created: BackingStore "rgw-resource"
      INFO[0002] ✅ Created: Secret "backing-store-secret-rgw-resource"

1. Create a CephObjectStore user. This also creates a secret containing the RGW credentials:

   apiVersion: ceph.rook.io/v1
   kind: CephObjectStoreUser
   metadata:
     name: <RGW-Username>
     namespace: openshift-storage
   spec:
     store: ocs-storagecluster-cephobjectstore
     displayName: "<Display-name>"

   1. Replace <RGW-Username> and <Display-name> with a unique username and display name.

2. Apply the following YAML for an S3-Compatible backing store:

   apiVersion: noobaa.io/v1alpha1
   kind: BackingStore
   metadata:
     finalizers:
     - noobaa.io/finalizer
     labels:
       app: noobaa
     name: <backingstore-name>
     namespace: openshift-storage
   spec:
     s3Compatible:
       endpoint: <RGW endpoint>
       secret:
         name: <backingstore-secret-name>
         namespace: openshift-storage
       signatureVersion: v4
       targetBucket: <RGW-bucket-name>
     type: s3-compatible

   1. Replace <backingstore-secret-name> with the name of the secret that was created with CephObjectStore in the previous step.
   2. Replace <bucket-name> with an existing RGW bucket name. This argument tells Multicloud Object Gateway which bucket to use as a target bucket for its backing store, and subsequently, data storage and administration.
   3. To get the <RGW endpoint>, see Accessing the RADOS Object Gateway S3 endpoint.

Procedure

1. In your OpenShift Storage console, click Storage → Overview → Object tab → Multicloud Object Gateway link.

               "Sid": "Example",
               "Effect": "Allow",
               "Principal": [
                       "john.doe@example.com"
               ],
               "Action": [
                   "s3:GetObject"
               ],
               "Resource": [
                   "arn:aws:s3:::john_bucket"
               ]
           }
       ]
   }

   There are many available elements for bucket policies with regard to access permissions.

   For details on these elements and examples of how they can be used to control the access permissions, see AWS Access Policy Language Overview.

   For more examples of bucket policies, see AWS Bucket Policy Examples.

   Instructions for creating S3 users can be found in Section 7.3, “Creating an AWS S3 user in the Multicloud Object Gateway”.

2. Using AWS S3 client, use the put-bucket-policy command to apply the bucket policy to your S3 bucket:

   # aws --endpoint ENDPOINT --no-verify-ssl s3api put-bucket-policy --bucket MyBucket --policy BucketPolicy

   Replace ENDPOINT with the S3 endpoint

   Replace MyBucket with the bucket to set the policy on

   Replace BucketPolicy with the bucket policy JSON file

   Add --no-verify-ssl if you are using the default self signed certificates

   For example:

   # aws --endpoint https://s3-openshift-storage.apps.gogo44.noobaa.org --no-verify-ssl s3api put-bucket-policy -bucket MyBucket --policy file://BucketPolicy

   For more information on the put-bucket-policy command, see the AWS CLI Command Reference for put-bucket-policy.

Procedure

1. In your OpenShift Storage console, navigate to Storage → Overview → Object tab → select the Multicloud Object Gateway link:

   

2. Under the Accounts tab, click Create Account:

   

3. Select S3 Access Only, provide the Account Name, for example, john.doe@example.com. Click Next:

   

4. Select S3 default placement, for example, noobaa-default-backing-store. Select Buckets Permissions. A specific bucket or all buckets can be selected. Click Create:

   

Procedure

1. Add the following lines to your application YAML:

   apiVersion: objectbucket.io/v1alpha1
   kind: ObjectBucketClaim
   metadata:
     name: <obc-name>
   spec:
     generateBucketName: <obc-bucket-name>
     storageClassName: openshift-storage.noobaa.io

   These lines are the Object Bucket Claim itself.

   1. Replace <obc-name> with the a unique Object Bucket Claim name.
   2. Replace <obc-bucket-name> with a unique bucket name for your Object Bucket Claim.

2. You can add more lines to the YAML file to automate the use of the Object Bucket Claim. The example below is the mapping between the bucket claim result, which is a configuration map with data and a secret with the credentials. This specific job will claim the Object Bucket from NooBaa, which will create a bucket and an account.

   apiVersion: batch/v1
   kind: Job
   metadata:
     name: testjob
   spec:
     template:
       spec:
         restartPolicy: OnFailure
         containers:
           - image: <your application image>
             name: test
             env:
               - name: BUCKET_NAME
                 valueFrom:
                   configMapKeyRef:
                     name: <obc-name>
                     key: BUCKET_NAME
               - name: BUCKET_HOST
                 valueFrom:
                   configMapKeyRef:
                     name: <obc-name>
                     key: BUCKET_HOST
               - name: BUCKET_PORT
                 valueFrom:
                   configMapKeyRef:
                     name: <obc-name>
                     key: BUCKET_PORT
               - name: AWS_ACCESS_KEY_ID
                 valueFrom:
                   secretKeyRef:
                     name: <obc-name>
                     key: AWS_ACCESS_KEY_ID
               - name: AWS_SECRET_ACCESS_KEY
                 valueFrom:
                   secretKeyRef:
                     name: <obc-name>
                     key: AWS_SECRET_ACCESS_KEY

   1. Replace all instances of <obc-name> with your Object Bucket Claim name.
   2. Replace <your application image> with your application image.

3. Apply the updated YAML file:

   # oc apply -f <yaml.file>

   1. Replace <yaml.file> with the name of your YAML file.

4. To view the new configuration map, run the following:

   # oc get cm <obc-name>

   1. Replace obc-name with the name of your Object Bucket Claim.

      You can expect the following environment variables in the output:

      • BUCKET_HOST - Endpoint to use in the application

      • BUCKET_PORT - The port available for the application

        • The port is related to the BUCKET_HOST. For example, if the BUCKET_HOST is https://my.example.com, and the BUCKET_PORT is 443, the endpoint for the object service would be https://my.example.com:443.
      • BUCKET_NAME - Requested or generated bucket name
      • AWS_ACCESS_KEY_ID - Access key that is part of the credentials
      • AWS_SECRET_ACCESS_KEY - Secret access key that is part of the credentials

Procedure

1. Use the command-line interface to generate the details of a new bucket and credentials. Run the following command:

   # noobaa obc create <obc-name> -n openshift-storage

   Replace <obc-name> with a unique Object Bucket Claim name, for example, myappobc.

   Additionally, you can use the --app-namespace option to specify the namespace where the Object Bucket Claim configuration map and secret will be created, for example, myapp-namespace.

   Example output:

   INFO[0001] ✅ Created: ObjectBucketClaim "test21obc"

   The MCG command-line-interface has created the necessary configuration and has informed OpenShift about the new OBC.

2. Run the following command to view the Object Bucket Claim:

   # oc get obc -n openshift-storage

   Example output:

   NAME        STORAGE-CLASS                 PHASE   AGE
   test21obc   openshift-storage.noobaa.io   Bound   38s

3. Run the following command to view the YAML file for the new Object Bucket Claim:

   # oc get obc test21obc -o yaml -n openshift-storage

   Example output:

   noobaa namespacestore create aws-s3 <namespacestore> --access-key <AWS ACCESS KEY> --secret-key <AWS SECRET ACCESS KEY> --target-bucket <bucket-name>

   1. Replace <namespacestore> with the name of the namespacestore.
   2. Replace <AWS ACCESS KEY> and <AWS SECRET ACCESS KEY> with an AWS access key ID and secret access key you created for this purpose.

   3. Replace <bucket-name> with an existing AWS bucket name. This argument tells Multicloud Object Gateway which bucket to use as a target bucket for its backing store, and subsequently, data storage and administration.

      You can also add storage resources by applying a YAML. First create a secret with credentials:

      apiVersion: v1
      kind: Secret
      metadata:
        name: <namespacestore-secret-name>
      type: Opaque
      data:
        AWS_ACCESS_KEY_ID: <AWS ACCESS KEY ID ENCODED IN BASE64>
        AWS_SECRET_ACCESS_KEY: <AWS SECRET ACCESS KEY ENCODED IN BASE64>

      You must supply and encode your own AWS access key ID and secret access key using Base64, and use the results in place of <AWS ACCESS KEY ID ENCODED IN BASE64> and <AWS SECRET ACCESS KEY ENCODED IN BASE64>.

      Replace <namespacestore-secret-name> with a unique name.

      Then apply the following YAML:

      apiVersion: noobaa.io/v1alpha1
      kind: NamespaceStore
      metadata:
        finalizers:
        - noobaa.io/finalizer
        labels:
          app: noobaa
        name: <namespacestore>
        namespace: openshift-storage
      spec:
        awsS3:
          secret:
            name: <namespacestore-secret-name>
            namespace: <namespace-secret>
          targetBucket: <target-bucket>
        type: aws-s3

   4. Replace <namespacestore> with a unique name.
   5. Replace <namespacestore-secret-name> with the secret created in the previous step.
   6. Replace <namespace-secret> with the namespace used to create the secret in the previous step.
   7. Replace <target-bucket> with the AWS S3 bucket you created for the namespacestore.

2. Run the following command to create a bucket class:

   noobaa bucketclass create namespace-bucketclass cache <my-cache-bucket-class> --backingstores <backing-store> --hub-resource <namespacestore>

   1. Replace <my-cache-bucket-class> with a unique bucket class name.
   2. Replace <backing-store> with the relevant backing store. You can list one or more backingstores separated by commas in this field.
   3. Replace <namespacestore> with the namespacestore created in the previous step.

3. Run the following command to create a bucket using an Object Bucket Claim resource that uses the bucket class defined in step 2.

   noobaa obc create <my-bucket-claim> my-app --bucketclass <custom-bucket-class>

   1. Replace <my-bucket-claim> with a unique name.
   2. Replace <custom-bucket-class> with the name of the bucket class created in step 2.

Procedure

1. Create a NamespaceStore resource. A NamespaceStore represents an underlying storage to be used as a read or write target for the data in Multicloud Object Gateway namespace buckets. From the MCG command-line interface, run the following command:

   noobaa namespacestore create ibm-cos <namespacestore> --endpoint <IBM COS ENDPOINT> --access-key <IBM ACCESS KEY> --secret-key <IBM SECRET ACCESS KEY> --target-bucket <bucket-name>

   1. Replace <namespacestore> with the name of the NamespaceStore.
   2. Replace <IBM ACCESS KEY>, <IBM SECRET ACCESS KEY>, <IBM COS ENDPOINT> with an IBM access key ID, secret access key and the appropriate regional endpoint that corresponds to the location of the existing IBM bucket.

   3. Replace <bucket-name> with an existing IBM bucket name. This argument tells Multicloud Object Gateway which bucket to use as a target bucket for its backing store, and subsequently, data storage and administration.

      You can also add storage resources by applying a YAML. First, Create a secret with the credentials:

      apiVersion: v1
      kind: Secret
      metadata:
        name: <namespacestore-secret-name>
      type: Opaque
      data:
        IBM_COS_ACCESS_KEY_ID: <IBM COS ACCESS KEY ID ENCODED IN BASE64>
        IBM_COS_SECRET_ACCESS_KEY: <IBM COS SECRET ACCESS KEY ENCODED IN BASE64>

      You must supply and encode your own IBM COS access key ID and secret access key using Base64, and use the results in place of <IBM COS ACCESS KEY ID ENCODED IN BASE64> and <IBM COS SECRET ACCESS KEY ENCODED IN BASE64>`.

      Replace <namespacestore-secret-name> with a unique name.

      Then apply the following YAML:

      apiVersion: noobaa.io/v1alpha1
      kind: NamespaceStore
      metadata:
        finalizers:
        - noobaa.io/finalizer
        labels:
          app: noobaa
        name: <namespacestore>
        namespace: openshift-storage
      spec:
        s3Compatible:
          endpoint: <IBM COS ENDPOINT>
          secret:
            name: <backingstore-secret-name>
            namespace: <namespace-secret>
          signatureVersion: v2
          targetBucket: <target-bucket>
        type: ibm-cos

   4. Replace <namespacestore> with a unique name.
   5. Replace <IBM COS ENDPOINT> with the appropriate IBM COS endpoint.
   6. Replace <backingstore-secret-name> with the secret created in the previous step.
   7. Replace <namespace-secret> with the namespace used to create the secret in the previous step.
   8. Replace <target-bucket> with the AWS S3 bucket you created for the namespacestore.

2. Run the following command to create a bucket class:

   noobaa bucketclass create namespace-bucketclass cache <my-bucket-class> --backingstores <backing-store> --hubResource <namespacestore>

   1. Replace <my-bucket-class> with a unique bucket class name.
   2. Replace <backing-store> with the relevant backing store. You can list one or more backingstores separated by commas in this field.
   3. Replace <namespacestore> with the namespacestore created in the previous step.

3. Run the following command to create a bucket using an Object Bucket Claim resource that uses the bucket class defined in step 2.

   noobaa obc create <my-bucket-claim> my-app --bucketclass <custom-bucket-class>

   1. Replace <my-bucket-claim> with a unique name.
   2. Replace <custom-bucket-class> with the name of the bucket class created in step 2.

Procedure

1. In the Multicloud Object Gateway user interface, from the Overview page, click Add Storage Resources:

   

2. In the window, click Deploy Kubernetes Pool:

   

3. In the Create Pool step create the target pool for the future installed nodes.

   

4. In the Configure step, configure the number of requested pods and the size of each PV. For each new pod, one PV is be created.

   
5. In the Review step, you can find the details of the new pool and select the deployment method you wish to use: local or external deployment. If local deployment is selected, the Kubernetes nodes will deploy within the cluster. If external deployment is selected, you will be provided with a YAML file to run externally.

6. All nodes will be assigned to the pool you chose in the first step, and can be found under Resources → Storage resources → Resource name:
