# 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  

## 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
Make gtfso a native Prometheus exporter  
Vulnerability Scanning  
Define strategy for version updates  
Use SOPS for secret management  
Terraform has minikube and flux providers
