Execute commands in pods and get result output in node.js

1. Have a cluster (microk8s is a nice super fast way to start locally)

2. Launch a minimum pod and connect to its shell:

kubectl run -i --tty busybox --image=busybox --restart=Never -- sh

3. Create a sample file inside of the pod:

mkdir /example && echo '{ "id": "junx8nvi8visygivlxvgilx" }' > /example/data.json

4. Run:

yarn
node index.js

5. Should get result:

Exited with status: Success
Retrieved instance ID from pod: junx8nvi8visygivlxvgilx
