This is an example Helm chart for tftpd, to demonstrate how to run a UDP service behind a LoadBalancer Service on minikube

Install this chart:

$ helm upgrade --install tftp ~/path/to/this/chart/

Wait until it is ready:

$ helm status tftp

Start tunnel to minikube LoadBalancers:

$ minikube tunnel

In another terminal, we can note the LoadBalancer IP:

$ kubectl get svc

Now we can use the tftp client to retrieve a file:

$ tftp $LOADBALANCERIP
tftp> verbose
Verbose mode on.
tftp> trace
Packet tracing on.
tftp> binary
mode set to octet
tftp> get file1.txt
getting from 10.104.126.213:file1.txt to file1.txt [octet]
sent RRQ <file=file1.txt, mode=octet>
received DATA <block=1, 31 bytes>
Received 31 bytes in 0.0 seconds [60783 bit/s]
tftp> quit

And make sure that the file has our expected contents:

$ cat file1.txt
contents of file1.txt go here!

This is meant as a simple demonstration. If you want to change the example data files in this application, you will find them in the templates/configmap.yaml as plain text.
