# Prometheus on Kubernetes
An example setup of Prometheus inside of Kubernetes, monitoring the Kubernetes
infrastructure itself as well as services running in Kubernetes. Used during a
workshop at [ContainerDays NYC][].
The setup and all manifests are copied from [CoreOS][]' [kube-prometheus][]
project. This repository split their project up in individual commits to show
the individual steps.
## Preparation
The examples require a running Kubernetes cluster as well as a configured
`kubectl` to talk to that cluster. Check the Kubernetes documentation for
examples.
If you don't have access to a Kubernetes cluster, you can use the [bootkube][]
or [minikube][] projects to start a cluster locally. Bootkube allows for a local
multi-node setup and easier monitoring of Kubernetes components.
You should be able to run `kubectl get pods --all-namespaces` and see some
output:
```bash
$ kubectl get pods --all-namespaces
NAMESPACE NAME READY STATUS RESTARTS AGE
kube-system kube-api-checkpoint-172.17.4.101 1/1 Running 0 35m
kube-system kube-apiserver-lpd8d 2/2 Running 0 37m
kube-system kube-controller-manager-325405546-3ygeg 1/1 Running 0 39m
kube-system kube-controller-manager-325405546-an3m0 1/1 Running 0 39m
kube-system kube-dns-v20-3531996453-vkxnp 3/3 Running 0 39m
kube-system kube-proxy-ks0u7 1/1 Running 0 37m
kube-system kube-proxy-zss6m 1/1 Running 0 17m
kube-system kube-scheduler-928627977-2mw8x 1/1 Running 0 39m
kube-system kube-scheduler-928627977-3llcb 1/1 Running 0 39m
```
After install the [kubernetes-dashboard][] the UI should be available at
[http://172.17.4.101:32010](http://172.17.4.101:32010/#/workload?namespace=_all):
```bash
kubectl --namespace=kube-system apply -f https://rawgit.com/kubernetes/dashboard/master/src/deploy/kubernetes-dashboard.yaml
```
## Running Prometheus
There are many options to install and configure Prometheus in Kubernetes.
The most basic one is to create the necessary pod spec, service spec and
deployment/petset spec on your own. There are various [Helm][] charts available
in the Kubernetes ecosystem to make it easier to share such specifications.
A very recent new option is to use [CoreOS][]' [prometheus-operator][] which
provides Kubernetes controller and extensions making the configuration of
Prometheus very easy.
The following command will install the Prometheus Operator and upload a
Prometheus specification. The operator will watch for such specs and configure
Prometheus accordingly.
```bash
scripts/deploy
