To complete the challenge you will need to do the following:
- Deploy Rancher
- Deploy a downstream K3s cluster with Rancher
- In Rancher use the Fleet/Continuous Delivery dashboard and create a new `Git Repo` pointing to this repository
If you followed these instructions correctly, Fleet will deploy an app called ctf in the cattle-fleet-system namespace of your K3s cluster. Check the output of the pod logs to see what the flag is!
