# Server Srtucture

## Base layer

* DKU VCM running ubuntu 22.04.2 LTS
* Docker CE with Docker compose

## Management layer

* Portainer BE (With free license)

## Service Layer

### Containers

* [**eclipse-mosquitto**](https://hub.docker.com/_/eclipse-mosquitto) for MQTT Broker
* [**postgres**](https://hub.docker.com/_/postgres) for orm DB system
* Server Layer for passing DB calls and accessing different testing parameters [**Repo**](https://github.com/FedCampus/IoT-Server) **Has been created**
* [**dpage/pgadmin4**](https://hub.docker.com/r/dpage/pgadmin4) for accessing DB for debug purposes

### API for access

* This part is still a work in progress a Nginx Reverse proxy may be deployed for better avaliability and may also allow for easier TLS & authentication
* This part will still be containerlized, but further research is needed

## Todo list

* [ ] \[\*] Decide on the Database Image to use
* [ ] \[\*] Provision the VM
* [ ] \[\*] Install Docker
* [ ] \[\*] Install Portainer and setup
* [ ] Develop the service layer (Not needed since MQTT will be handeled by ML)
* [ ] Decide on API (MQTT will be used directly)
