Because you must configure the azure-blob-storage provider with parameters specific to your account (but can leave all other parameters with the recommended values), if you choose to use the cluster-azure-blob-storage template, your binarystore.xml configuration file should look like this:
<config version="2">
<chain template="cluster-azure-blob-storage"/>
<provider id="azure-blob-storage" type="azure-blob-storage">
<accountName>XXXXXX</accountName>
<accountKey>XXXXXX</accountKey>
<endpoint>https://<ACCOUNT_NAME>.blob.core.windows.net/</endpoint>
<containerName><NAME></containerName>
</provider>
</config>
