Challenge

The infrastructure is set up with minikube and fluxcd. The bitnami PostgreSQL HA chart is used for a highly available PostgreSQL database backend.
The app consists of two parts: an import job for PostgreSQL and the HA API deployment with the /success endpoint and a ReplicaSet of 2.

• Database: PostgresqlHA
• Import: gtfso-import
• API: gtfso-vbb
  Monitoring: kube-prometheus-stack Vulnerability Scanning: Trivy

Clone repository

$ git clone https://git.e2m.io/mue/obch
$ cd obch

Setup minikube and flux

Optionally remove remnants of previous minikube clusters

$ minikube delete --all

# The above was not sufficient to setup a new cluster
# See also: https://github.com/kubernetes/minikube/issues/17683
# Additionally deleting the local minikube config folder helped:
$ rm -rf ~/.minikube

Setup cluster and deploy app

run sh sources 'setup-cluster' and 'deploy'

$ ./run.sh

Setup cluster

$ ./setup-cluster

Deploy Service

$ ./deploy

Stop cluster

$ minikube stop

TODOs / Notes

gtfso-import needs the database secret for import
Add monitoring target for gtfs/vbb to prometheus
Define strategy for version updates
Consider SOPS for secret management
Terraform has minikube and flux providers
