Appendix C: How to change MongoDB settings

Changing MongoDB service port

By default, the MongoDB service is reachable via port 27018. If you want to change that to something else, say 9487, modify the docker-compose.yml:

services:
  mongo:
    restart: always
    build:
      context: ./mongo
      dockerfile: Dockerfile
    ports:
      - "27018:27017" # Change this to "9487:27017"

If you want to run tests using your own port, modify tests/__init__.py, and change it from 27018 to 9487.

Changing other MongoDB configurations

All of the configuration values are in config.ini.

Encryption

In order to properly encrypt things, several things are required:

• encrypted field in config.ini should be true
• encryption_key in config.ini should be a 96 bytes long string

The encryption key will be stored in MongoDB, in a collection named __keyVault in the database specified in config.ini. There should be none or only one document in the collection.
