10.3. Enabling log based bucket replication

Procedure

1. In the OpenShift Web Console, navigate to Storage Object Storage Object Bucket Claims.
2. Click Create ObjectBucketClaim.
3. Enter the name of ObjectBucketName and select StorageClass and BucketClass.
4. Select the Enable replication check box to enable replication.
5. In the Replication policy section, select the Optimize replication using event logs checkbox.

6. Enter the name of the bucket that will contain the logs under Event log Bucket.

   If the logs are not stored in the root of the bucket, provide the full path without s3://

7. Enter a prefix to replicate only the objects whose name begins with the given prefix.

Procedure

1. Create a secret with credentials to be used by the namespacestores.

   apiVersion: v1
   kind: Secret
   metadata:
     name: <namespacestore-secret-name>
   type: Opaque
   data:
       TenantID: <AZURE TENANT ID ENCODED IN BASE64>
       ApplicationID: <AZURE APPLICATIOM ID ENCODED IN BASE64>
       ApplicationSecret: <AZURE APPLICATION SECRET ENCODED IN BASE64>
       LogsAnalyticsWorkspaceID: <AZURE LOG ANALYTICS WORKSPACE ID ENCODED IN BASE64>
       AccountName: <AZURE ACCOUNT NAME ENCODED IN BASE64>
       AccountKey: <AZURE ACCOUNT KEY ENCODED IN BASE64>

2. Create a NamespaceStore backed by a container created in Azure.

   For more information, see Adding a namespace bucket using the OpenShift Container Platform user interface.

3. Create a new Namespace-Bucketclass and OBC that utilizes it.
4. Check the object bucket name by looking in the YAML of target OBC, or by listing all S3 buckets, for example, - s3 ls.

5. Use the following template to apply an Azure replication policy on your source OBC by adding the following in its YAML, under .spec:

   replicationPolicy:'{"rules":[ {"rule_id":"ID goes here", "sync_deletions": "<true or false>"", "destination_bucket":object bucket name"}
    ], "log_replication_info":{"endpoint_type":"AZURE"}}'

   sync_deletion

   Specify a boolean value, true or false.

   destination_bucket

   Make sure to use the name of the object bucket, and not the claim. The name can be retrieved using the s3 ls command, or by looking for the value in an OBC’s YAML.

Verification steps

1. Write objects to the source bucket.
2. Wait until MCG replicates them.
3. Delete the objects from the source bucket.
4. Verify the objects were removed from the target bucket.

Procedure

1. In the OpenShift Web Console, navigate to Storage Object Storage Object Bucket Claims.
2. Click Create new Object bucket claim.
3. (Optional) In the Replication rules section, select the Sync deletion checkbox for each rule separately.

4. Enter the name of the bucket that will contain the logs under Event log Bucket.

   If the logs are not stored in the root of the bucket, provide the full path without s3://

5. Enter a prefix to replicate only the objects whose name begins with the given prefix.
