Go to the logs, you have, most of time, far more detail on the error. Check it out and share the logs if you aren't able to fix the issue — guillaume blaquiere
Hmm, with a closer look to your dockerfile, you don't have a CMD line that execute the webserver at the end. Nothing is running, nothing is started on the $PORT, so, there is an error. Do you serve only static content? — guillaume blaquiere
Thanks for the reply man I used apache in dockerfile instead of fpm and edited my dockerfile,now it works great, should have used it before — Naveen Raj

RUN a2enmod rewrite

RUN printf "#!/bin/bash\n/usr/sbin/apache2ctl -D FOREGROUND" > /startScript.sh
RUN chmod +x /startScript.sh

RUN cd /var/www/html

COPY ./composer.json /var/www/html/composer.json

RUN composer update /var/www/html/ --no-dev --ignore-platform-reqs "vendor/*"
RUN chmod -R 0777 /var/www/html/writable

RUN apt-get clean \
    && rm -r /var/lib/apt/lists/*

EXPOSE ${PORT}
VOLUME ["/var/www/html", "/var/log/apache2", "/etc/apache2"]

CMD ["bash", "/startScript.sh"]

I used apache instead of fpm and it works but I still don't know why fpm is not working
