Chapter 11. Caching policy for object buckets

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>

   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>

      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 (OBC) 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 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>

   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>

      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.
