# 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](https://kustomize.io/). 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](https://docs.kubelinter.io):
|
|
|
|
```
|
|
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`.
|
|
|
|

## 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
|
|
```
|
