Lab Optional - Manually Create a TCP Load Balancer and Origin Pool¶

Origin Pool Configuration

The Origin Pool will point to the pods on on the vk8s cluster.

On the Distributed Cloud console and in the Distributed Apps workspace, under Manage, hover over Load Balancers, then click Origin Pools
Click the Add Origin Pool button.
On the configuration page, click the JSON button.
In the textual config editor page select the other JSON button, and then select YAML.
Click into the main editor window and then press CTRL-A to select all of the prepopulated text.

Press the DELETE key (or the BACKSPACE key) to remove all the text.

There should only be left a blank line on line 1.

Copy and paste the following YAML configuration into the editor window:

metadata:
   name: kind-python-mosquitto
   namespace: kind-python  ## Replace with your namespace
   labels: {}
   annotations: {}
   disable: false
spec:
  origin_servers:
   - k8s_service:
      service_name: mosquitto.kind-python  ## Replace with your namespace
      site_locator:
         virtual_site:
            tenant: f5-xc-lab-app-jqguisgi
            namespace: shared

  no_tls: {}
  port: 1883
  same_as_endpoint_port: {}
  healthcheck: []
  loadbalancer_algorithm: LB_OVERRIDE
  endpoint_selection: LOCAL_ONLY

TCP Load Balancer Configuration

The TCP Load Balancer will point to the Origin Pool, which will allow interest access into the MATT containers.

On the Distributed Cloud console and in the Distributed Apps workspace, under Manage, hover over Load Balancers, then click TCP Load Balancers
Click the Add TCP Load Balancer button.
On the New TCP Load Balancer configuration page, click the JSON button and select YAML as before.
Clear any configuration in the editor window as before.

Copy and paste the following YAML configuration into the editor window and replace the fields with your namespace.

metadata:
  name: kind-python-mqtt ## Replace with your namespace
  namespace: kind-python ## Replace with your namespace
  labels: {}
  annotations: {}
  disable: false
spec:
  domains:
    - kind-python.useast.lab-app.f5demos.com ## Replace with your namespace
    - kind-python.europe.lab-app.f5demos.com ## Replace with your namespace
    - kind-python.uswest.lab-app.f5demos.com ## Replace with your namespace
