Netflux on Kubernetes

This is a learning project to migrate the self-hosted services that I host at netflux.io to Kubernetes.

This repository contains the Kubernetes manifests, which are built using Kustomize. Helm chart dependencies are inflated and managed in this repository to improve observability. The cluster is deployed to DigitalOcean managed K8S in production, but can be easily applied to a local cluster for testing.

Building

The manifests can be built with:

make dev

and applied with:

make dev | kubectl apply -f -

Cluster setup

cert-manager

cert-manager should only be installed in production. It is not managed inside this repository.

See: https://cert-manager.io/docs/installation/helm/

helm repo add jetstack https://charts.jetstack.io
helm repo up
helm install cert-manager jetstack/cert-manager --namespace cert-manager --create-namespace --version v1.8.0 --set installCRDs=true

# create issuers
kubectl apply -f cert-manager/issuer-staging.yml
kubectl apply -f cert-manager/issuer-production.yml

This should be sufficient for cert-manager to issue certificates automatically when the tls.enabled value is set to true.
