F5 Distributed Cloud Update Origin Pools

In this section we will update the existing HTTP load balancer to include the SPA and API vK8S deployments.

Exercise 1: Add SPA Origin Pool to HTTP LB

In this exercise you will add the new vK8s SPA service to the existing brew-spa origin pool.

1. In F5 Distributed Cloud Console ensure you are in the Load Balancers context.

   

2. Ensure you have selected your assigned namespace

3. Navigate the menu to Manage -> Origin Pools.

   Warning

   Make sure you go to “Manage” and not “Virtual Hosts” (scroll down)

   

4. Select the … link for the brew-spa Origin Pool.

5. Click the Edit button.

   

6. Under the Origin Servers section, click the Add item button.

7. Enter the following variables:

   Variable	Value
   Select Type of Origin Server	K8s Service Name of Origin Server on given Sites
   Service Name	brews-spa.your_namespace
   Select Site or Virtual Site	Virtual Site
   Virtual Site	your_namespace-vsite
   Select Network on the site	vK8s Networks on Site

   

8. Click the Save and Exit button to close the Origin Pool dialogue.

Exercise 2: Add API Origin Pool to HTTP LB

In this exercise you will add the new vK8s API service to the existing brew-api origin pool.

The steps are identical to Exercise 1 except you will choose the brews-api origin pool and you will specify the brews-api vK8s service.

Variable	Value
Select Type of Origin Server	K8s Service Name of Origin Server on given Sites
Service Name	brews-api.your_namespace
Select Site or Virtual Site	Virtual Site
Virtual Site	your_namespace-vsite
Select Network on the site	vK8s Networks on Site

Exercise 3: Check HTTP LB Origin Servers

Now that we have updated the SPA and API origin pools we need to check the health of the origin pools in the HTTP Load Balancer.

Please be sure to reload your “brews” application in a web browser to generate some traffic first.

1. Navigate the menu to Virtual Hosts -> HTTP Load Balancers

   

2. Click on your “brews-lb” load balancer.

3. Click on the Origin Servers tab.

4. Click on the Refresh link

You should see three origin pools that are green:

• UDF server

• vK8s spa service

• vK8s api service

You should be able to open a browser and check that the demo application looks like the screen shot below:
