Netflux on Kubernetes
This repo contains Kubernetes manifests for deploying various self-hosted
services to the netflux.io domain.
All of the manifests are built using Kustomize. I avoid Helm charts whenever possible, but when they're needed (Prometheus, Grafana, etc) the charts are inflated into this repository for visibility and auditability.
The manifests are deployed to a DigitalOcean managed k8s cluster in production, and can be easily applied to a local cluster for testing and development.
Of course all this would in many ways be simpler with a docker-compose.yml shipped to a virtual host, which is exactly how everything used to be deployed. This project is mostly a fun learning exercise.
Git
The main git repo is hosted at: https://git.netflux.io/rob/netflux-kubernetes
It is also mirrored on GitHub: https://github.com/rfwatson/netflux-kubernetes
Building
The manifests can be built with:
make dev
and applied with:
make dev | kubectl apply -f -
Linting
The manifests are linted with kube-linter:
kube-linter lint .
Helm charts
When required, Helm charts can be inflated with:
# install or update the prometheus helm chart:
make inflate name=prometheus chart=prometheus-community/prometheus
An optional values file can be provided, e.g. deploy/base/values/prometheus.yaml.
URLs

Cluster setup
Development
To initialize the local PostgreSQL database:
# Ensure PostgreSQL helm chart is installed (only used in development env):
cd deploy
make dev | k apply -l app.kubernetes.io/name=postgresql -f -
kubectl port-forward dev-postgresql-0 5432
psql -h localhost -f ../kind/bin/setup-dev-db.sql
To connect locally to the Nginx ingress controller:
sudo -E kubectl port-forward dev-ingress-nginx-controller-abcdef1234-ab123 80:80 443:443 22:22
Or
sudo -E kubectl port-forward $(kubectl get pods | grep "dev-ingress-nginx-controller.*Running" | awk '{print $1}') 80:80 443:443 22:22
