Chapter 10. Multicloud Object Gateway

Procedure

1. In the OpenShift Web Console, click Storage OpenShift Data Foundation.
2. Click the Backing Store tab.
3. Click Create Backing Store.

4. 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 the 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 10.4.2, “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 the 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 the MCG that it can use this bucket for the system.
5. Click Create Backing Store.

Verification steps

1. In the OpenShift Web Console, click Storage OpenShift Data Foundation.
2. Click the Backing Store tab to view all the backing stores.

Procedure

1. From the MCG command-line interface, run the following 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>

   Copy to Clipboard Toggle word wrap

   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

      Copy to Clipboard Toggle word wrap
   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 the MCG 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"

      Copy to Clipboard Toggle word wrap

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>"

   Copy to Clipboard Toggle word wrap
   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

   Copy to Clipboard Toggle word wrap
   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 the MCG which bucket to use as a target bucket for its backing store, and subsequently, data storage and administration.

   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 10.7.3, “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

   Copy to Clipboard Toggle word wrap
   1. Replace ENDPOINT with the S3 endpoint.
   2. Replace MyBucket with the bucket to set the policy on.
   3. Replace BucketPolicy with the bucket policy JSON file.

   4. 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

      Copy to Clipboard Toggle word wrap

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

      Note

      The principal element specifies the user that is allowed or denied access to a resource, such as a bucket. Currently, Only NooBaa accounts can be used as principals. In the case of object bucket claims, NooBaa automatically create an account obc-account.<generated bucket name>@noobaa.io.

      Note

      Bucket policy conditions are not supported.

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

   Copy to Clipboard Toggle word wrap

   These lines are the OBC itself.

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

2. You can add more lines to the YAML file to automate the use of the OBC. 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 claims the Object Bucket from NooBaa, which creates a bucket and an account.

   apiVersion: batch/v1
   kind: Job
   metadata:
     name: testjob
   spec:

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

3. Apply the updated YAML file:

   # oc apply -f <yaml.file>

   Copy to Clipboard Toggle word wrap

   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> -o yaml

   Copy to Clipboard Toggle word wrap

   Replace obc-name with the name of your OBC.

   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

   Copy to Clipboard Toggle word wrap

   Replace <obc-name> with a unique OBC name, for example, myappobc.

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

   Example output:

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 the MCG namespace buckets. From the MCG command-line interface, run the following command:

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

   Copy to Clipboard Toggle word wrap
   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 the MCG 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>

      Copy to Clipboard Toggle word wrap

      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

      Copy to Clipboard Toggle word wrap
   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>

   Copy to Clipboard Toggle word wrap
   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 (OBC) resource that uses the bucket class defined in step 2.

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

   Copy to Clipboard Toggle word wrap
   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 the MCG 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>

   Copy to Clipboard Toggle word wrap
   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 the MCG 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>

      Copy to Clipboard Toggle word wrap

      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

      Copy to Clipboard Toggle word wrap
   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>

   Copy to Clipboard Toggle word wrap
   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>

   Copy to Clipboard Toggle word wrap
   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. Log in to OpenShift Web Console.
2. From the MCG user interface, click Overview Add Storage Resources.
3. In the window, click Deploy Kubernetes Pool.
4. In the Create Pool step create the target pool for the future installed nodes.
5. In the Configure step, configure the number of requested pods and the size of each PV. For each new pod, one PV is to be created.
6. 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.
7. All nodes will be assigned to the pool you chose in the first step, and can be found under Resources Storage resources Resource name.
