Similar question have been asked many times and I have gone through most of them and still I am not able to solve the problem.
I am running Apache2 and PHP 7 FPM in different docker containers and they are not able to connect to each other. The connection fails with following errors.

Note: PHP-FPM is listening for connections on port 9000 and its working properly. When I try to access it from my host OS (for instance http://localhost/ instead of http://localhost:8080 I am able to connect and get the desired output).
I have also tried setting up permission on the www/html and try making www-data the owner.
Can someone please help me get this working?
Thanks in advance for your help.
In your examples localhost or 127.0.0.1 is local to the containers (not the host). So, when Apache tries to connect to FPM at 127.0.0.1:9000, it is actually trying to connect to itself (the Apache container only).
What you want to do is have Apache connect to the FPM container. The easiest way to do this with Docker networking is to use the service name from Docker Compose. In your case, the service name is php and will be available at the DNS name php from the Apache container.
Thus, your Apache configuration should be:
SetHandler "proxy:fcgi://php:9000"
