This is the **Part VI** of more global topic tutorial. [Back to first part]({{< ref "/posts/10-build-your-own-kubernetes-cluster" >}}) for intro.
Dev Only - skippable
Add runner-01
## Monitoring
## Gitea
Monitoring is a critical part of any production grade platform. It allows you to be proactive and react before your users are impacted. It also helps get a quick visualization of cluster architecture and current usage.
* Validate DB & redis access
* Enable SSH access
* First commit test with basic DotNet sample app
### Monitoring node pool
## Concourse CI
As well as storage pool, creating a dedicated node pool for monitoring stack is a good practice in order to scale it separately from the apps.
* Automatic build on commit
* Push to Gitea Container Registry
You now have a good understanding of how to create a node pool, so apply next configuration from our 1st Terraform project:
## Flux
{{< highlight host="demo-kube-hcloud" file="kube.tf" >}}
* Automatic deployment on commit
```tf
module "hcloud_kube" {
//...
## 3rd check ✅
agent_nodepools = [
//...
{
name = "monitor"
server_type = "cx21"
location = "nbg1"
count = 1
private_interface = "ens10"
labels = [
"node.kubernetes.io/server-usage=monitor"
]
taints = [
"node-role.kubernetes.io/monitor:NoSchedule"
]
}
]
}
```
We have everything we need for app building with automatic deployment ! Go [next part]({{< ref "/posts/15-build-your-own-kubernetes-cluster-part-6" >}}) to add complete monitoring stack !
{{< /highlight >}}
### Prometheus Stack
When using k8s, the standard de facto is to install [Prometheus stack](https://artifacthub.io/packages/helm/prometheus-community/kube-prometheus-stack). It includes all necessary CRDs and element for a proper monitoring stack.
Go back to 2nd Terraform project and apply next configuration:
{{< highlight host="demo-kube-k3s" file="prometheus.tf" >}}
```tf
```
{{< /highlight >}}
### Grafana
...
### Some dashboards
## Logging with Loki
...
## 5th check ✅
We now have a full monitoring suite ! Go [next part]({{< ref "/posts/16-build-your-own-kubernetes-cluster-part-7" >}}) to add continuous integration stack.
