Laravel & Dockerfile Deployment Issue on DigitalOcean App Platform

I am attempting to deploy a Laravel application using a Dockerfile on DigitalOcean’s App Platform, following the guidelines provided in this tutorial: https://docs.digitalocean.com/products/app-platform/reference/dockerfile/

The Docker image builds successfully, but it fails to deploy.

Here is my Dockerfile:

# Use the official PHP runtime image as the base image
FROM php:8.2-fpm

# Set the working directory inside the container
WORKDIR /var/www/html

# Install system dependencies and PHP extensions
RUN apt-get update && apt-get install -y \
    libpng-dev \
    libjpeg-dev \
    libfreetype6-dev \
    libzip-dev \
    libmagickwand-dev \
    && docker-php-ext-configure gd --with-freetype --with-jpeg \
    && docker-php-ext-install -j$(nproc) gd pdo pdo_mysql zip pcntl

# Install Composer globally
RUN curl -sS https://getcomposer.org/installer | php -- --install-dir=/usr/local/bin --filename=composer

# Install Node.js and npm
RUN apt-get install -y nodejs npm

# Copy the Laravel application files into the container
COPY . .

# Install Laravel dependencies
RUN composer install --no-interaction

# Run npm install and npm run build
RUN npm install
RUN npm run build

# Expose port 80 for Nginx
EXPOSE 80

# Install and configure Nginx
RUN apt-get install -y nginx
RUN rm /etc/nginx/sites-available/default
COPY nginx.conf /etc/nginx/sites-available/default

# Start the PHP-FPM server
#another comment
CMD ["php-fpm"]

nginx.conf:

server {
    listen 80;
    server_name mydomain.com;

    root /var/www/html/public;
    index index.php;

    location / {
        try_files $uri $uri/ /index.php?$query_string;
    }

    location ~ \.php$ {
        include fastcgi_params;
        fastcgi_pass php-fpm:80; # Use the name of your PHP-FPM service
        fastcgi_index index.php;
        fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
    }
}

Deploy Log looks like success, but labeled as “Deploy Error: Health Checks”:

NOTICE: fpm is running, pid 1 NOTICE: ready to handle connections

I attempted to deploy without Nginx, but I couldn’t configure the app entrypoint as “/public.”

I am feeling frustrated and overwhelmed. Bleeding from eyes. Any assistance would be greatly appreciated.

it’s laravel 10.
