# FaSTTUBe Corona Tracker

Small webapp to track who was in which room at which time to backtrace
potential viral infections.

For Ideas, Progress, and Bugs visit
[Issues](https://git.fasttube.de/FaSTTUBe/ftracker/issues).

## Requirements

- Unixoid system (linux, BSD, macOS). Windows might also work.
- `python` 3.6+ (might be `python3` on your system)
- `pip` for python 3+ (might be `pip3` on your system)

## How to run

(Dev setup, for prod deployment see below)

```bash
# clone, cd into repo
pip install -e .
python3 -m ftracker
```

Edit `config.ini` to tune your installation.

Then, point your browser at <http://localhost:5000/>.

## Installation/Deployment

There are 2 methods: Docker and Manual.

### Method A: Docker

Pull the container from docker hub using

```bash
sudo docker pull fasttube/ftracker
```

OR build the container locally with

```bash
sudo docker build . -t fasttube/ftracker
```

Then, if you want the container to also handle SSL so it can run standalone you
need to pass it a domain and email so it can obtain a certificate from `Let's
encrypt`. Use the first path in the `-v` option to point to your config file:

```bash
sudo docker run \
	-it --rm \
	--name ftracker \
	-e DOMAIN=example.com \
	-e LE_EMAIL=admin@example.com \
	-p 80:80 \
	-p 443:443 \
	-v /your/full/path/to/config.ini:/etc/ftracker/config.ini \
	fasttube/ftracker
```

Otherwise you can run it without SSL (maybe behind your own web+ssl server)
using just

```bash
sudo docker run \
	-it --rm \
	--name ftracker \
	-p 80:80 \
	-v /your/full/path/to/config.ini:/etc/ftracker/config.ini \
	fasttube/ftracker
```

If those work in the foreground and everything looks okay, you can start them
without `-it --rm` and with `-d` instead to run them in the background. Keep in
mind that it can take around 10 seconds to fully start.

To stop/start/uninstall the container afterwards, run:

```bash
docker stop ftracker  # might take a few seconds
docker start ftracker # continue running
docker rm -f ftracker # uninstall
```

### Method B: Manual

#### 1. FTracker Backend

Install backend system wide:
```bash
# clone, cd into repo
sudo -H pip install . # Use -e if you want to hack on the backend while installed.
```

#### 2. WSGI Server + Service file

You need a WSGI Middleware (using `Flask`'s included `werkzeug` is discouraged
for production environments). I recommend `uwsgi` since it's flexible, fast and
has `nginx` integration. A sample configuration file as well as service
description files for both `systemd` and `rc` are included in `res/` for you to
adapt (file paths etc.) and install to your system (The `systemd` service file
still untested though, feel free to leave feedback).

#### 3. Webserver

You need a webserver. I recommend `nginx` because it's the industry standard
and fast. A sample config file is included in `res/` for you to adapt (domain,
SSL certs) and install to your system. The configuration should include:
Webroot in `web/` with a fallback to the WSGI handler for the backend.

Enabling SSL (https) and redirecting http to https is strongly encouraged, i
recommend using `Let's Encrypt`'s `certbot` to easily obtain certificates.

#### 4. Customization

Edit `config.ini` to your liking. Restart the backend by restarting the `uwsgi`
service, e.g. `sudo systemctl restart ftracker` or `sudo service ftracker
restart`
