# 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](https://skupper.io/start/index.html).

## 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!

```
