I am able to access web-server from host machine and php code is also being processed by the php-fpm installed therein.

I am worried about the frequent restart required for nginx by supervisord. What is it that I am doing wrong?

PS: Please ask for details before downvoting the question. I have posted after enough research on my own. This is my last resort!!!

It looks like nginx is immediately exiting. That could be from a configuration file error, permission problem, etc, and the best way to find out is to run it by hand inside the container to make sure it starts and remains running. Given that this is nginx, at least one issue is that you are not starting it in the foreground. The standard way nginx is run in other containers is with:

nginx -g "daemon off;"

You can see this in the Dockerfile used to build nginx.
