In a specific region, you can use namespaces to isolate resources and services to enhance security. Creating namespaces helps prevent conflicts between resources and services, simplifies management and maintenance, and improves work efficiency. This topic describes how to create a namespace.
Considerations
Creating too many namespaces in a single instance can increase the blast radius and overload the database. This affects the instance's runtime Service-Level Agreement (SLA).
Create and use namespaces for an instance based on distinct isolation requirements, such as different environments or usage scenarios. Limit the number of namespaces to 10 or fewer.
When you create an instance, MSE automatically generates the default namespace public. This namespace cannot be modified or deleted. If you do not create a custom namespace, you can use this default namespace to isolate resources and services.
Procedure
Log on to the MSE console, and select a region in the top navigation bar.
In the left-side navigation pane, choose Microservices Registry > Instances.
On the Instances page, click the name of the instance.
In the navigation pane on the left, click Namespace.
On the Namespace page, click Create namespace. In the Create namespace dialog box, set Namespace Name and Namespace ID, and then click OK.
The created namespace is added to the namespace list.
What to do next
After you create a namespace, you can perform the following operations in the Actions column of the namespace list.
View the namespace: Click View to view the namespace information.
Edit the namespace: Click Edit and follow the prompts to modify the namespace information.
Delete the namespace: Click Delete and follow the prompts to delete the namespace.
