To deploy the monitoring stack on your K3s cluster, there are four parameters that need to be configured in the `vars.jsonnet` file:
1. Set `k3s.enabled` to `true`.
2. Change your K3s master node IP(your VM or host IP) on `k3s.master_ip`.
3. Edit `suffixDomain` to have your node IP with the `.nip.io` suffix. This will be your ingress URL suffix.
