<p>By default, the DynamoDB registry stores data in the table named <code>external-dns</code> and it needs to exist before configuring ExternalDNS to use the DynamoDB registry.<br />
If the DynamoDB table has a different name, it may be specified using the <code>--dynamodb-table</code> flag.<br />
If the DynamoDB table is in a different region, it may be specified using the <code>--dynamodb-region</code> flag.</p>
<p>The following command creates a DynamoDB table with the name: <code>external-dns</code>:</p>
<blockquote>
<p>The table must have a partition (HASH) key named <code>k</code> of type string (<code>S</code>) and the table must NOT have a sort (RANGE) key.</p>

<p>The ExternalDNS deployment from <a href="../../tutorials/aws/#deploy-externaldns">Deploy ExternalDNS</a> needs the following modifications:</p>
<ul>
<li><code>--registry=txt</code> should be changed to <code>--registry=dynamodb</code></li>
<li>Add <code>--dynamodb-table=external-dns</code> to specify the name of the DynamoDB table, its value defaults to <code>external-dns</code></li>
<li>Add <code>--dynamodb-region=us-east-1</code> to specify the region of the DynamoDB table</li>
</ul>
