This contains a solution of the Netguru's recruiment task.

Deployment

Deployment is handled automatically via a CI script.

Deployment is done to a Docker Swarm platform, since I'm a big fan, and I'm still learning Kubernetes.

I realize that Docker Swarm is a dead end, as it isn't supported anymore, but I've got 1,5-FTE worth of jobs on my hands.

Configuration

You need to provide your settings in following environment variables:

• DB_HOST (default is postgres)
• DB_USER (default is postgres)
• DB_PASS (default is postgres)
• DB_NAME (default is postgres)
• DB_PORT (default is 5432)

You should also pick a env called SECRET_KEY it should be a random sequence of characters. If you don't provide it, a reasonably default value is supplied, but since it has already been used it isn't safe anymore. CHANGE IT!

Volumes

The application needs a volume marked at /data to store files. Because storing files in a database is an antipattern.

Monitoring

Logs

You will just have to forgive me that I failed to hook up any loggers for it. Any Python-based logger will do, I sincerely recommends seq-log

Metrics

The solution actively exports metrics at port 81. You can hook up Prometheus to it. It exports the metrics thanks to my excellent satella library and django-satella-metrics adapter.

Traces

The solution fully supports tracing. You can tweak the settings in settings.py file to install for example a Jaeger instance.

I failed to deploy that on your test environment since I'm pretty much strapped for time.

BTW: If you're not already doing tracing, you should totally consider it.
