Hi. I see that you have set up docker secrets for MQTT, Is it the same that has to be done for mongo as well?

Weell there are a few steps:

1. modify docker-compose Mongodb service to work with username and password.
   You can test it's ok by starting the service and connect to it with username and password from mongo shell
2. Add MongoDb secrets in secrets section
3. Modify all docker-compose services that use MongoDb and add the secrets there
4. Modify all python services to support connection with MongoDb credentials. I would make a function in utils.py that would handle connetion to eliminate duplicate code
5. Run all tests to see if things are not broken

I've got stuck in step 1, i can't remember why..could not set MongoDb username and password.

You can start here: https://hub.docker.com/_/mongo theoretically it should be simple :)

mongo:
image: mongo
restart: always
environment:
MONGO_INITDB_ROOT_USERNAME: root
MONGO_INITDB_ROOT_PASSWORD: example

Got it. This information is good enough for me to get started. I am also working on #20 and thinking of using pytest for it.

Great, keep me updated. If i can help you with anything ask me and we'll discuss it here.
Thanks , great work !

Happy to work with you!
