test-udp-bridge

This test is using an external udp brigde to expose services in Skupper.

You can find the udp bridge code in this repository: https://github.com/grs/skupper-udp-bridge

environment setup

For this test, we will need to set up two skupper sites and create a link between them.

In order to do that, you can follow this tutorial.

steps

1. udp-server setup

Deploy the udp-server in one of the skupper sites:

kubectl apply -f deployment-server.yaml

Export the deployment as a service using the external udp bridge:

skupper expose deployment udp-server --port 8000 --protocol udp --bridge-image=quay.io/skupper/bridge-server

2. run udp-client

In the other cluster, run the udp-client:

kubectl run udp-client --image=quay.io/skupper/udp-client --restart="OnFailure"

The client will send a message using the UDP protocol to the address udp-server:8000

3. check the logs

The udp-server will print in its log the message received from the client:

udp-client logs

$ kubectl logs -f udp-client

Sent message to server: Hello, server!

udp-server logs

 $ kubectl logs -f udp-server-7dc558794c-clxts                  
 Listening for UDP packets on :8000
 Received 14 bytes from 10.244.0.7:33016: Hello, server!
