gke-prometheus

This deploys a Prometheus instance to Google Kubernetes Engine, in the namespace monitoring. This deployment is meant to integrate with an NGINX Ingress Controller, a Lets Encrypt Kubernetes Certificate Manager, and an Oauth Proxy deployment.

Requirements

• A Google Cloud account with Google Kubernetes Engine configured.
• The monitoring namespace.
• An NGINX Ingress Controller and a LetsEncrypt kube-cert-manager deployment. Note you will want/need this to access it publically, but it is not necessary to simply run Prometheus and Grafana in Kubernetes. This particular deployment uses it.
• An oauth2_proxy service deployment.

It integrates with these components to provide an ingress, a TLS secret, and an authentication mechanism.

Deployment

Before deploying, edit the cert.yml and prometheus-ingress.yml files. Change EXAMPLE.ORG to your domain. Note the requirements above, with the NGINX Ingress Controller, kube-cert-manager, and oauth!

The deployment script can quickly deploy Prometheus:

# if it doesn't exist, create the namespace - `kubectl create namespace monitoring`
./deploy.sh

This runs the following:

kubectl create -f service-account/prometheus-service-account.yml
kubectl create -f service-account/prometheus-roles.yml
kubectl create -f service-account/prometheus-role-bindings.yml
kubectl -n monitoring create configmap prometheus-config --from-file ./config/prometheus.yml
kubectl create -f rules/prometheus-rules.yml
kubectl create -f pvc.yml
kubectl create -f prometheus-deployment.yml
kubectl create -f cert.yml
kubectl create -f prometheus-service.yml
kubectl create -f prometheus-ingress.yml
