Dokku postgres服务名称和database.yml

Question

When I created my Ruby on Rails application, I used the Unix “dot” convention to refer to the current directory. My current directory's name was fireworks_app , so my application was given the name of fireworks_app .

The database.yml file was created accordingly, so that for each environment the corresponding database was named with the formula fireworks_app_environment .

I would like to install Dokku in my VPS. I wonder what alternatives do I have to naming my Dokku application fireworks_app , and the Dokku postgres service respecting what is reported in database.yml ( fireworks_app_production ).

This would imply that I create my Dokku application and my postgres service as follows:

$ dokku apps:create fireworks_app
$ dokku postgres:create fireworks_app_production
$ dokku postgres:link fireworks_app_production fireworks_app

This looks to me a bit awkward: there is no need to specify production for my VPS, for instance.
Instead, I would prefer to name my application fireworks and all my services fireworks . Thus I would use instead the following more compact commands and names:

$ dokku apps:create fireworks
$ dokku postgres:create fireworks
$ dokku postgres:link fireworks fireworks

Is it possible in this regard to edit database.yml and change fireworks_app_production into a more compact fireworks ? What changes can I (and am I expected to) do to avoid appending _app and _app_production to my Dokku application and service names?

Answer 1

You don't have to worry about the database.yml file, you can do this if you want without problems

$ dokku apps:create fireworks
$ dokku postgres:create fireworks
$ dokku postgres:link fireworks fireworks

you can use the name that you want on the app and on postgres. just be sure that you link the ones that you created, no mater the name.
