          Thanks for using docker_dir_env!
          Make sure to provide the databases credentials by configuring them with
          `EDITOR=vim rails credentials:edit` OR
          `EDITOR=vim rails credentials:edit -e development` (and the other envs)

           Your can use your favourite editor instead of vim.

          Provide the following structure inside the credentials:
          database:
            username: YOUR_USERNAME
            password: YOUR_PASSWORD
        README
      end
    end
  end
