View Kubernetes objects in a namespace	Learn how to set the Kubernetes namespace context in a Docker Enterprise Edition cluster.	Docker EE, UCP, Kubernetes, namespace

With Docker Enterprise Edition, administrators can filter the view of Kubernetes objects by the namespace the objects are assigned to. You can specify a single namespace, or you can specify all available namespaces.

Create two namespaces

In this example, you create two Kubernetes namespaces and deploy a service to both of them.

1. Log in to the UCP web UI with an administrator account.
2. In the left pane, click Kubernetes.
3. Click Create to open the Create Kubernetes Object page.
4. In the Object YAML editor, paste the following YAML.

apiVersion: v1
kind: Namespace
metadata:
 name: blue
---
 apiVersion: v1
 kind: Namespace
 metadata:
  name: orange

5. Click Create to create the blue and orange namespaces.

{: .with-border}

Deploy services

Create a NodePort service in the blue namespace.

1. Navigate to the Create Kubernetes Object page.
2. In the Namespace dropdown, select blue.
3. In the Object YAML editor, paste the following YAML.

apiVersion: v1
kind: Service
metadata:
  name: app-service-blue
  labels:
    app: app-blue
spec:
  type: NodePort
  ports:
    - port: 80
      nodePort: 30080
  selector:
    app: app-blue

4. Click Create to deploy the service in the blue namespace.

Repeat the previous steps with the following YAML, but this time, select orange from the Namespace dropdown.

apiVersion: v1
kind: Service
metadata:
  name: app-service-orange
  labels:
    app: app-orange
spec:
  type: NodePort
  ports:
    - port: 80
      nodePort: 30081
  selector:
    app: app-orange

View services

Currently, the Namespaces view is set to the default namespace, so the Load Balancers page doesn't show your services.

1. In the left pane, click Namespaces to open the list of namespaces.
2. In the upper-right corner, click the Set context for all namespaces toggle. The indicator in the left pane changes to All Namespaces.
3. Click Load Balancers to view your services.

{: .with-border}

Filter the view by namespace

With the Set context for all namespaces toggle set, you see all of the Kubernetes objects in every namespace. Now filter the view to show only objects in one namespace.

1. In the left pane, click Namespaces to open the list of namespaces.
2. In the orange namespace, click the More options icon and in the context menu, select Set Context.

{: .with-border}

3. Click Confirm to set the context to the orange namespace. The indicator in the left pane changes to orange.
4. Click Load Balancers to view your app-service-orange service. The app-service-blue service doesn't appear.

To view the app-service-blue service, repeat the previous steps, but this time, select Set Context on the blue namespace.
