This repository collects Kubernetes manifests, [Grafana](http://grafana.com/) dashboards, and [Prometheus rules](https://prometheus.io/docs/prometheus/latest/configuration/recording_rules/) combined with documentation and scripts to provide easy to operate end-to-end Kubernetes cluster monitoring with [Prometheus](https://prometheus.io/) using the Prometheus Operator.

The content of this project is written in [jsonnet](http://jsonnet.org/). This project could both be described as a package as well as a library.

Components included in this package:

* The [Prometheus Operator](https://github.com/prometheus-operator/prometheus-operator)

* Highly available [Prometheus](https://prometheus.io/)

* Highly available [Alertmanager](https://github.com/prometheus/alertmanager)

* [Prometheus node-exporter](https://github.com/prometheus/node_exporter)

* [Prometheus blackbox-exporter](https://github.com/prometheus/blackbox_exporter)

* [Prometheus Adapter for Kubernetes Metrics APIs](https://github.com/kubernetes-sigs/prometheus-adapter)

* [kube-state-metrics](https://github.com/kubernetes/kube-state-metrics)

* [Grafana](https://grafana.com/)

This stack is meant for cluster monitoring, so it is pre-configured to collect metrics from all Kubernetes components. In addition to that it delivers a default set of dashboards and alerting rules. Many of the useful dashboards and alerts come from the [kubernetes-mixin project](https://github.com/kubernetes-monitoring/kubernetes-mixin), similar to this project it provides composable jsonnet as a library for users to customize to their needs.

## Prerequisites

You will need a Kubernetes cluster, that's it! By default it is assumed, that the kubelet uses token authentication and authorization, as otherwise Prometheus needs a client certificate, which gives it full access to the kubelet, rather than just the metrics. Token authentication and authorization allows more fine grained and easier access control.

This means the kubelet configuration must contain these flags:

* `--authentication-token-webhook=true` This flag enables, that a `ServiceAccount` token can be used to authenticate against the kubelet(s). This can also be enabled by setting the kubelet configuration value `authentication.webhook.enabled` to `true`.

* `--authorization-mode=Webhook` This flag enables, that the kubelet will perform an RBAC request with the API to determine, whether the requesting entity (Prometheus in this case) is allowed to access a resource, in specific for this project the `/metrics` endpoint. This can also be enabled by setting the kubelet configuration value `authorization.mode` to `Webhook`.

This stack provides [resource metrics](https://github.com/kubernetes/metrics#resource-metrics-api) by deploying

the [Prometheus Adapter](https://github.com/kubernetes-sigs/prometheus-adapter).

This adapter is an Extension API Server and Kubernetes needs to be have this feature enabled, otherwise the adapter has

no effect, but is still deployed.

## Compatibility

The following Kubernetes versions are supported and work as we test against these versions in their respective branches. But note that other versions might work!

## Quickstart

This project is intended to be used as a library (i.e. the intent is not for you to create your own modified copy of this repository).

Though for a quickstart a compiled version of the Kubernetes [manifests](manifests) generated with this library (specifically with `example.jsonnet`) is checked into this repository in order to try the content out quickly. To try out the stack un-customized run:

* Create the monitoring stack using the config in the `manifests` directory:

```shell

# Create the namespace and CRDs, and then wait for them to be available before creating the remaining resources

# Note that due to some CRD size we are using kubectl server-side apply feature which is generally available since kubernetes 1.22.

# If you are using previous kubernetes versions this feature may not be available and you would need to use kubectl create instead.

kubectl apply --server-side -f manifests/setup

kubectl wait \

	--for condition=Established \

	--all CustomResourceDefinition \

	--namespace=monitoring

kubectl apply -f manifests/

```

We create the namespace and CustomResourceDefinitions first to avoid race conditions when deploying the monitoring components.

Alternatively, the resources in both folders can be applied with a single command

`kubectl apply --server-side -f manifests/setup -f manifests`, but it may be necessary to run the command multiple times for all components to

be created successfully.

* And to teardown the stack:

```shell

kubectl delete --ignore-not-found=true -f manifests/ -f manifests/setup

```

### minikube

To try out this stack, start [minikube](https://github.com/kubernetes/minikube) with the following command:

```shell

$ minikube delete && minikube start --kubernetes-version=v1.23.0 --memory=6g --bootstrapper=kubeadm --extra-config=kubelet.authentication-token-webhook=true --extra-config=kubelet.authorization-mode=Webhook --extra-config=scheduler.bind-address=0.0.0.0 --extra-config=controller-manager.bind-address=0.0.0.0

```

The kube-prometheus stack includes a resource metrics API server, so the metrics-server addon is not necessary. Ensure the metrics-server addon is disabled on minikube:

```shell

$ minikube addons disable metrics-server

```
