How to manage Namespaces in Temporal Cloud

Join the Temporal Cloud waitlist

Access to Temporal Cloud is currently by invitation only. You can join the waitlist.

Create a Namespace

info

The user who creates a Namespace is automatically granted Namespace Admin permission for that Namespace.

tip

By default, each account has a quota of 10 Namespaces. If you want to increase this limit, open a support ticket.

Information needed to create a Namespace

To create a Namespace in Temporal Cloud, gather the following information:

Create a Namespace using Temporal Cloud UI

  1. Gather the information listed earlier in Information needed to create a Namespace.
  2. Go to the Temporal Cloud UI and log in.
  3. On the left side of the window, click Namespaces.
  4. On the Namespaces page, click Create Namespace in the upper-right portion of the window.
  5. On the Create Namespace page in Name, enter the Namespace Name.
  6. In Region, select the region in which to host this Namespace.
  7. In Retention Period, specify a value from 1 to 30 days. When choosing this value, consider your needs for Event History versus the cost of maintaining that Event History. Typically, a development Namespace has a short retention period and a production Namespace has a longer retention period. (If you need to change this value later, contact Temporal Support.)
  8. In Certificate, paste the CA certificate for this Namespace.
  9. Click Create Namespace.

Create a Namespace using tcld

This functionality is in development.

Access Namespaces

Each Namespace in Temporal Cloud has two unique endpoints, both of which include the Namespace Id.

  • For programmatic access, a gRPC endpoint in the form <NamespaceId>.tmprl.cloud; for example, accounting-production.f45a2.tmprl.cloud:7233.
  • For accessing Temporal Web UI, an HTTPS endpoint in the form web.<namespaceId>.tmprl.cloud; for example, https://web.accounting-production.f45a2.tmprl.cloud.
