How to force composer to automatically ignore warrning? - automation

Question

I'm making shell script which will install symfony 4 on ubuntu automatically. Since I'm using apache I have to execute:
composer require symfony/apache-pack
However, that command asks me to confirm:
composer require symfony/apache-pack
The recipe for this package comes from the "contrib" repository, which is open to community contributions.
Review the recipe at https://github.com/symfony/recipes-contrib/tree/master/symfony/apache-pack/1.0
Do you want to execute this recipe?
[y] Yes
[n] No
[a] Yes for all packages, only for the current installation session
[p] Yes permanently, never ask again for this project
(defaults to n): y
And I can't use --no-interaction options since default value is "n". How can I change this command not to ask me to confirm this action, but to automatically installs this apache pack?

Answer 1

This does not answer the question per se, but you can get rid of your specific warning per project if you add the following to your composer.json:
"extra": {
"symfony": {
"allow-contrib": true
}
}
or, even better, you can use Composer itself to set the flag before installing symfony/apache-pack:
composer config extra.symfony.allow-contrib true
This will make possible for Flex to install contrib recipes (i.e. recipes provided by the community) automatically, without asking for permission.
