更改Symfony2项目的默认配置文件

Question

Context

I have a simple Symfony2 project (only command line commands). This project includes an app/config.yml file, containing information used for dependency injection creation.

For example, app/config.yml contains:

github:
    token: abcdefgh

And src/Foo/Resources/config/github.yml (services files) contains:

services:
    github.client:
        class: Github\Client
        calls:
            - ['authenticate', [%github.token%, null, 'http_token']]

The file app/config.yml is loaded by Application::__construct() function.

When I run app/console mycommand, it uses the defined token.

Needs

I need to be able to run my commands using different configurations. For now, I replace manually the app/config.yml file, but it's crappy.

To do this, I thought about 2 possible solutions:

• Be able to specify another app/config.yml file when I run app/console mycommand --f=app/config2.yml.
• Have another configuration file for specific command usage, and use it with app/console mycommand --f=myconfig.yml. The thing is the dependency injection can not work or be updated after the application is run.

I don't know how to do one of this solution (or a third one, no matters). If it's a common behavior, can you point me some documentation or example to do something like this?

Answer 1

It is totally possible by using different environements, check out the doc : http://symfony.com/doc/current/cookbook/configuration/environments.html

Typically you will specify the environement using --env=myenv.
