Create Origin Pools

Before we create an HTTP load balancer to expose our services on the internet, we’ll define “Origin Pools” for our application’s services.

Exercise 1: Create SPA Origin Pool

We will first create an Origin Pool that refers to the single-page application service running in our UDF site.

1. Start in F5 Distributed Cloud Console and switch to the Load Balancers context.

   

2. Ensure you have selected your assigned namespace

3. Navigate the menu to go to “Manage”->”Load Balancers”->”Origin Pools”. Click on Add Origin Pool.

   

4. Enter the following variables:

   Variable	Value
   Name	brews-spa-pool
   Select Type of Origin Server	IP address of Origin Server on given Sites
   IP	10.1.1.4
   Site	the UDF site name configured in the previous lab
   Select Network on the site	Outside Network
   Port	8081

   

5. Under the List of Health Check(s) section, click the Add item button.

6. Click the Health Check object dropdown list. Click the Create new healthcheck button.

7. Enter the following variables:

   Variable	Value
   name	brews-spa-check

   

8. Click the configure button under “HTTP Health Check” and enter the following variables:

   Variable	Value
   path	/products

   

9. Click Apply to exit the “Health Check HTTP Parameters” dialogue.

10. Click Continue to return to the “Origin Pool” configuration.

11. Click the Save and Exit button to create the Origin Pool.

Exercise 2: Create API Origin Pool

In this exercise, you will repeat the steps from the previous exercise for the API service.

Use the following variables:

Variable	Value
Name	brews-api-pool
Select Type of Origin Server	IP address of Origin Server on given Sites
IP	10.1.1.4
Site	the UDF site name configured in the previous lab
Select Network on the site	Outside Network
Port	8000

In the List of Health Check(s) section, create a new “HTTP healthcheck” name “brews-api-check” targeting the path “/api/stats”.

Exercise 3: Troubleshoot Origin Pools

1. Click on the 3 dots (…) link for the pool you would like to troubleshoot.

2. Click the Show Child Objects button.

   

3. Click on the Status tab.

4. Select your UDF Site.

5. Validate that the JSON payload shows that “Validation” is “Successful” and “Operational” is “Installed”.

If “Validation” isn’t “Successful” and “Operational” isn’t “Installed”, you can verify the IP addresses, ports and healthcheck in the Origin Pool configuration.
