Dapr namespacing provides isolation and multi-tenancy across many capabilities, giving greater security. Typically applications and components are deployed to namespaces to provide isolation in a given environment, such as Kubernetes.

Dapr supports namespacing in service invocation calls between applications, when accessing components, sending pub/sub messages in consumer groups, and with actors type deployments as examples. Namespacing isolation is supported in both self-hosted and Kubernetes modes.

To get started, create and configure your namespace.

{{< tabs "Self-Hosted" "Kubernetes">}}

{{% codetab %}}

In self-hosted mode, specify the namespace for a Dapr instance by setting the NAMESPACE environment variable.

{{% /codetab %}}

{{% codetab %}}

On Kubernetes, create and configure the namespace:

kubectl create namespace namespaceA
kubectl config set-context --current --namespace=namespaceA

Then deploy your applications into this namespace.

{{% /codetab %}}

{{< /tabs >}}
