postgres service name and database.yml file about dokku-postgres HOT 3 CLOSED

We don't currently allow you to rename the postgres database that is created when you create a postgres service, so your best bet is to name it application_name_environment and then link appropriately.

IIRC you can just change the name in your config/database.yml to match the loaded service.

If you create a service:

dokku postgres:create SERVICE_NAME

Then the database name will be

SERVICE_NAME

Please see the documentation for further details.

@josegonzalez I understood how to assign a name to a postgres service, thank you.
However, I was mainly concerned about what name to choose and if there is any restriction.

In Ruby on Rails, the database configuration file is config/database.yml where each environment has its own configuration records, included the database name which is inferred by the name of the application: application_name_environment.
So, for the production environment we have application_name_production. There are also other useful records, such as the connection pool.

So I wonder: do I have to stick with the name contained in config/database.yml when I assign a name to the postgres service?
