Files for creating a kind cluster with metallb

kind is great, but it comes without loadbalancer by default. Duffie Cooley wrote this great tutorial how to integrate metallb into kind: https://mauilion.dev/posts/kind-metallb/

I automated the process of creating a multi-node kind cluster with metallb for myself. Putting these files up in case someone else finds them useful.

To use

Usage: ./kind-with-metallb <kind config> <metallb config>

With the example files: ./kind-with-metallb multinodecluster.yaml kind-metallb-config.yaml

To test

To test the setup apply the content of the demo directory:

$ kubectl apply -f demo/
deployment.apps/echo created
service/echo created

Use kubectl get all to see what was created:

 k get all
NAME                       READY   STATUS    RESTARTS   AGE
pod/echo-56f77f694-5k56c   1/1     Running   0          9m8s

deployment.apps/echo   3/3     3            3           9m8s

NAME                             DESIRED   CURRENT   READY   AGE
replicaset.apps/echo-56f77f694   3         3         3       9m8s

Now connect your browser to http://172.17.255.1:8080 and reload the page repeatedly. You should see the output from all three pods eventually. (Make sure to bypass the cache - e.g. press Ctrl-F5 in firefox.)
