# Kubernetes NixOps cluster setup
# NixOps Kubernetes clusters
This repository contains a batteries included, production ready, opinionated
Kubernetes cluster setup. It only requires editing two simple configuration
files to deploy a fully functional cluster using NixOps.
Together, NixOS and Kubernetes is a powerful combination. NixOS enables
programmatic configuration of the base Kubernetes system services at the OS
level. Just enabling the basic service is still a long way from having a
production ready, multi node Kubernetes cluster up and running. Setting up a
cluster at the OS level gives you a functional system shell, lacking most of the
services needed for actually deploying, accessing and monitoring services.
This project will do to things: It will configure the cluster at the OS level,
setting up services, networking, certificates, access tokens etc. It will then
bootstrap the running Kubernetes instance, fixing permissions and configuring
the following services:
* Helm for deploying services
* Nginx-ingress for external access
* cert-manager with issuers (Let's encrypt, cluster-ca and self-sign)
* nfs-client-provisioner for automatic volume management
* kubernetes-dashboard for managing the cluster and services
* metrics-server for monitoring
* Prometheus, node exporters and grafana for monitoring
