kubernetes-prometheus

Background

This Prometheus set up has a very specific use case. This is a combination of various other sources. If you want to create a prometheus in a separate namespace with RBAC control, then this is for you!

Usage

Currently, this set up works with Kubernetes v1.7.1, at the time of writing v1.8.0 has not been released for Kops

Run

From the root directory, apply the following:

kubectl apply -f namespace.yml
kubectl apply -f configmap.yml
kubectl apply -f roles.yml
kubectl apply -f deployment.yml
kubectl apply -f service.yml

A service is configured but not exposed to the public. This service a dummy template, you can either attach it to a AWS Elastic Load Balancer or expose a Node Port.

To access Prometheus, we are going to port forward your localhost port to the pod directly:

kubectl get pods -n prometheus-dev | awk '{ if (NR!=1) {print "kubectl port-forward " $1 " -n prometheus-dev 9090:9090"} }' | bash

Ensure that port 9090 on localhost is not being used by another service

In your web browser enter:

http://localhost:9090

This should redirect you to the Prometheus page.
