$ kubectl apply -f manifests/ # This command sometimes may need to be done twice (to workaround a race condition).
```
If you get an error from applying the manifests, run the `make deploy` or `kubectl apply -f manifests/` again. Sometimes the resources required to apply the CRDs are not deployed yet.
## Customizing for K3s
To have your [K3s](https://github.com/rancher/k3s) cluster and the monitoring stack on it, deploy K3s with `curl -sfL https://get.k3s.io | sh -`.
Now to deploy the monitoring stack on your K3s cluster, there are three parameters to be configured on `vars.jsonnet`:
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.
After changing these values, run `make` to build the manifests and `k3s kubectl apply -f manifests/` to apply the stack to your cluster. In case of errors on some resources, re-run the command.
Now you can open the applications:
* Grafana on [https://grafana.[your_node_ip].nip.io](https://grafana.[your_node_ip].nip.io),
* Prometheus on [https://prometheus.[your_node_ip].nip.io](https://prometheus.[your_node_ip].nip.io)
* Alertmanager on [https://alertmanager.[your_node_ip].nip.io](https://alertmanager.[your_node_ip].nip.io)
There are some dashboards that shows no values due to some cadvisor metrics not having the complete metadata. Check the open issues for more information.
## Updating the ingress suffixes
To avoid rebuilding all manifests, there is a make target to update the Ingress URL suffix to a different suffix (using nip.io) to match your host IP. Run `make change_suffix IP="[IP-ADDRESS]"` to change the ingress route IP for Grafana, Prometheus and Alertmanager and reapply the manifests. If you have a K3s cluster, run `make change_suffix IP="[IP-ADDRESS] K3S=k3s`.
## Customizing
The content of this project consists of a set of jsonnet files making up a library to be consumed.
