Running

Dependencies

The only dependencies to run the services in this repository are:

• docker
• docker-compose

Environment Variables

The program looks for the following environment variables:

• DB_USER: The postgres database username that gets used within the postgres connection string (Default: root).
• DB_PASS: The postgres database password that gets used within the postgres connection string (Default: root).
• DB_NAME: The postgres database name that gets used within the postgres connection string (Default: user).
• DB_HOST: The postgres database host name that gets used within the postgres connection string (Default db).
• DB_PORT: The postgres database port that gets used within the postgres connection string (Default: 5432).

If the environment variable has a supplied default and none are set within the context of the host machine, then the default will be used.

To set any given environment variable, simply execute the following pattern, replacing [ENV_NAME] with the name of the environment variable and [ENV_VALUE] with the desired value of the environment variable: export [ENV_NAME]=[ENV_VALUE]. To unset any set environment variable, simply execute the following pattern, replacing [ENV_NAME] with the name of the environment variable: unset [ENV_NAME].

Make Rule

To run the services simply execute the following command:

make run

This will stop any containers defined by the compose file if already running and then rebuild the containers using the compose file. The main daemon (main) will be available at localhost:8080 and the postgres instance will be available at localhost:5432.

To stop the services simply execute the following command:

make stop

To down the services simply execute the following command:

make down
