AMQPS Symfony 信使和 Heroku

Question

I'm using CloudAMQP though Heroku's add-on ( https://elements.heroku.com/addons/cloudamqp ) with the « Little Lemur » plan. I'm building a PHP Symfony application and I want to connect to AMQP through SSL but it says in the documentation that:

If you want to use TLS/SSL encrypted AMQP, you must also provide a CA certificate. Define the certificate path in the amqp.cacert PHP.ini setting (eg amqp.cacert = /etc/ssl/certs) or in the cacert parameter of the DSN (eg amqps://localhost?cacert=/etc/ssl/certs/). » ( https://symfony.com/doc/current/messenger.html#amqp-transport )

My issue is that I have no idea where is located the cacert file on Heroku.

Can you help me with this please?

Answer 1

I've found the solution, for those who wants to know how to deal with it on Heroku: you need to download the root CA of CloudAMQP ( https://www.cloudamqp.com/docs/faq.html#how-do-i-authenticate-the-identity-of-your-server-tls-certificates ) and put it in your source code, for example in the public folder.

Then, just set the path in the MESSENGER_DSN env variable like this XXX?cacert=/app/public/cacertfilename.cer
