Database

Setting up a DATABASE_GROUP and its connection credentials.

1. If you haven’t done so, create an empty file called credentials.yaml in your RAPIDS root directory:

2. Add the following lines to credentials.yaml and replace your database-specific credentials (user, password, host, and database):

   MY_GROUP:
     database: MY_DATABASE
     host: MY_HOST
     password: MY_PASSWORD
     port: 3306
     user: MY_USER
   

3. Notes

   1. The label [MY_GROUP] is arbitrary but it has to match the [DATABASE_GROUP] attribute of the data stream you choose to use.

   2. Indentation matters

   3. You can have more than one credentials group in credentials.yaml

Upgrading from ./.env from RAPIDS 0.x

In RAPIDS versions 0.x, database credentials were stored in a ./.env file. If you are migrating from that type of file, you have two options:

1. Migrate your credentials by hand:

   change .env format

   [MY_GROUP]
   user=MY_USER
   password=MY_PASSWORD
   host=MY_HOST
   port=3306
   database=MY_DATABASE
   

   to credentials.yaml format

   MY_GROUP:
     user: MY_USER
     password: MY_PASSWORD
     host: MY_HOST
     port: 3306
     database: MY_DATABASE
   

2. Use the migration script we provide (make sure your conda environment is active):

   python tools/update_format_env.py
   

Connecting to localhost (host machine) from inside our docker container.

If you are using RAPIDS’ docker container and Docker-for-mac or Docker-for-Windows 18.03+, you can connect to a MySQL database in your host machine using host.docker.internal instead of 127.0.0.1 or localhost. In a Linux host, you need to run our docker container using docker run --network="host" -d moshiresearch/rapids:latest and then 127.0.0.1 will point to your host machine.
