Identifying a shared AWS Cloud Map namespace - AWS Cloud Map

Identifying a shared AWS Cloud Map namespace

Owners and consumers can identify shared namespaces using the AWS Cloud Map console and AWS CLI. The namespace owner can be identified by using the ResourceOwner property. The AWS account that creates a service or registers an instance in the shared namespace can be identified by using the CreatedByAccount property.

AWS Cloud Map console
To identify a shared namespace using the AWS Cloud Map console

  1. Sign in to the AWS Management Console and open the AWS Cloud Map console at https://console.aws.amazon.com/cloudmap/.

  2. On the Namespaces page, under Resource Owner, you can find the ID of the AWS account that owns the namespace.

  3. Choose the Domain name of the namespace you want to identify.

  4. On the Namespace: namespace-name page, in the Namespace information section, under Resource owner, you can find the ID of the AWS account that owns the namespace.

AWS CLI

To identify a shared namespace using the AWS CLI, use the list-namespaces command. The command returns the namespaces that you own and namespaces that are shared with you. The ResourceOwner field shows the AWS account ID of the namespace owner.

The following list-namespaces call is made by account 111122223333.
