Deploying Symfony 4 to Heroku

Question

I have set up a new symfony 4 project that I am trying to deploy on heroku. I have the app set up and running successfully locally. I bascially followed the instructions from the heroku tutorial here. However, this tutorial is only written for symfony versions 2 and 3.

I had set up a symfony 3 app in the past successfully, I had to create a Procfile to direct the heroku server to the web/ directory, as per the instructions in the "Best Practices" section. In this S4 installation I don't see a web/ folder, so I didn't create a Procfile. Heroku uses a default command in this case.

I have created 2 config vars in heroku config: APP_ENV, SYMPHONY_ENV both are set to prod. I deploy the app the heroku, it all deployed successfully, but when I try to access the page, I just get a 403 Forbidden. In the logs I get this, which is maybe the correct functionality since I didn't write any code yet:

[autoindex:error] [pid 116:tid 139699079337728] [client 10.5.228.216:17171] AH01276: Cannot serve directory /app/: No matching DirectoryIndex (index.php,index.html,index.htm) found, and server-generated directory index forbidden by Options directive

I don't see an app folder, but I do see a folder called public with an index file inside.

Does anyone have experience deploying the new version of Symfony 4 to Heroku, if so any tips would be greatly appreciated. Thanks!

have you tried it? the public root folder changed from 'web' to 'public' in Symfony 4. — LBA

@LBA i just tried it and thanks for the simple suggestion it seems to have worked, although now I am getting an execption: PHP Fatal error: Uncaught Symfony\Component\Routing\Exception\NoConfigurationException in /app/var/cache/prod/srcProdProjectContainerUrlMatcher.php Which seems like its OK since I haven't yet configured anything and this heroku server app is set to production — jeffery_the_wind

@LBA yes thank you I put in the controller for the base route and the site works, seems silly. I should have tried earlier what you suggested but somehow it didn't seem obvious. Thanks. — jeffery_the_wind

On Symfony 4 the web folder was replaced by public. You still need to create the Procfile file and add this line:

web: vendor/bin/heroku-php-apache2 public/

In my case I defined a Procfile with the following content :

web: $(composer config bin-dir)/heroku-php-apache2 public/

But it was not enough, I had to install apache-pack with composer :

composer require apache-pack (using symfony flex) or composer require symfony/apache-pack

(I found the solution on the heroku-buildpack-php repository)

The best solution is to create a Procfile in the root of your repository, with the following content:

web: $(composer config bin-dir)/heroku-php-apache2 public/
