An example setup where a cronJob creates jobs for long running jobs using job expansion. The setup is a star wars server that randomly returns a set of characters that should work for a long time. A cronJob is used to schedule the work of each character by creating, deleting and listing jobs. If a character is already working the cronJob will skip creating a new job so that the character is not overworked.
Minikube was used for this playground and the images need to be built locally.

eval $(minikube docker-env)
make allSome of the usefull parts of the code is:
- Service account setup for the cron job scheduler/Manifest.yaml
