create_public_dns_namespace#
- ServiceDiscovery.Client.create_public_dns_namespace(**kwargs)#
Creates a public namespace based on DNS, which is visible on the internet. The namespace defines your service naming scheme. For example, if you name your namespace
example.com
and name your servicebackend
, the resulting DNS name for the service isbackend.example.com
. You can discover instances that were registered with a public DNS namespace by using either aDiscoverInstances
request or using DNS. For the current quota on the number of namespaces that you can create using the same Amazon Web Services account, see Cloud Map quotas in the Cloud Map Developer Guide.Warning
The
CreatePublicDnsNamespace
