503 "Service Unavailable" of Docker container with Laravel 8 in Google Cloud - php

Question

I am trying to run Laravel 8 (with the database!) in Google Cloud. Deployment is done via Cloud Run with GitHub CI Trigger
What I have done so far:
I created all necessary Docker files for building the Docker image and container like the Dockerfile and docker-composer.yml in my apps doc root.
Because my app needs a backend and a database, I created an nginx.conf-file and an int_db.sql file, to seed the database.
Dockerfile
FROM php:7.4-fpm
# Arguments defined in docker-compose.yml
ARG user=hannes
ARG uid=1002
# Install system dependencies
RUN apt-get update && apt-get install -y \
git \
curl \

libonig-dev \
libxml2-dev \
zip \
unzip
# Clear cache
RUN apt-get clean && rm -rf /var/lib/apt/lists/*
# Install PHP extensions
RUN docker-php-ext-install pdo_mysql mbstring exif pcntl bcmath gd
# Get the latest Composer

# Create system user to run Composer and Artisan Commands

RUN useradd -u 1002 -G www-data,root -d /home/$user $user
RUN mkdir -p /home/$user/.composer && \
chown -R $user:$user /home/$user
# Set working directory

}
}
In my local Docker environment, the Laravel 8 app gets successfully built and is working well, if i request the app via http://localhost:8000/.
So I created a Cloud Run Service in Google Cloud with a CI trigger of my GitHub Repo. So every time I push my branch, my Cloud Run Service is triggered and builds my app.
The build is finished successfully in Cloud Build.
Problem: if an open the apps link, I get a 503 Service Unavailable error
Web
Network Status
What the log tells me:

Any help is much appreciated. Stay safe.

There is a big confusion.
Cloud Run needs Dockerfile and that should expose proper HTTP service on port 8080.
So docker-compose is not used by Cloud Run.
Make sure for Cloud Run that your Dockerfile expose port 8080.
make sure your container also has the HTTP server and the PHP executables.
What I see at first is that your Dockerfile doesn't have a webserver and doesn't expose port 8080.
docker-compose is only for local development.
