I want to dockerize my laravel learning app and have been unable to find simple tutorial that runs without errors. Each one is different and fails so I created my own. Here is how my Dockerfile look like, my first attempt

# stage 1: start from composer
FROM composer:2.6.5 as build
WORKDIR /app

# copy all the code
COPY . .

# run composer to update
RUN composer update --prefer-dist --no-dev --no-interaction --ignore-platform-req=ext-http --ignore-platform-req=ext-xdebug

# stage 2: get the php latest image
FROM php:8.3.0RC6-zts-bullseye as production

# update the image
RUN apt-get update && apt-get install -y curl libpng-dev libonig-dev libxml2-dev

# add necessary libraries
RUN docker-php-ext-install pdo_mysql mbstring exif pcntl bcmath gd

# clean the apt cache
RUN apt-get clean && rm -rf /var/lib/apt/lists/*

WORKDIR /app

# copy all code from stage 1
COPY --from=build /app /var/www/html

# move the production file to the image
COPY .env.production .env

# RUN a2enmod rewrite
RUN php artisan config:cache && 
    php artisan route:cache && 
    chmod 777 -R /var/www/html/storage/ && 
    chown -R www-data:www-data /var/www/ && 

ENTRYPOINT ["php", "artisan", "serve", "-host 0.0.0.0", "-port 8080" ]

Needsless to say it failed at various steps specially when setting permissions for directories in container. Also libraries could not be installed for instance

mbstring
gd

So i gave up on the idea of creating it myself and used ChatGPT to generate one for me, I had to modify it though as before the default one failed again.

# Stage 1: Build the application
FROM php:8.3.0RC6-cli as builder

# Set working directory
WORKDIR /app

# Install dependencies
RUN apt-get update && apt-get install -y 
    git 
    unzip 
    && rm -rf /var/lib/apt/lists/*

# Install composer
COPY --from=composer:latest /usr/bin/composer /usr/bin/composer

# Copy Laravel application files
COPY . .

# Install dependencies using composer
RUN composer install --no-dev --no-interaction --no-progress --no-suggest --ignore-platform-req=ext-http --ignore-platform-req=ext-xdebug
RUN docker-php-ext-install pdo_mysql
#RUN docker-php-ext-install mbstring
RUN docker-php-ext-install exif
RUN docker-php-ext-install pcntl
RUN docker-php-ext-install bcmath
#RUN docker-php-ext-install gd

# Generate an optimized autoloader
RUN composer dump-autoload --optimize --classmap-authoritative

# Generate the application key
RUN php artisan key:generate

# Build the application
RUN php artisan config:cache
RUN php artisan route:cache
#RUN php artisan view:cache

# Stage 2: Create final image
FROM php:8.3.0RC6-cli

# Set working directory
WORKDIR /app

# Copy built application from the builder stage
COPY --from=builder /app .

# Expose the application port (if needed)
EXPOSE 8000

# Run the application
CMD ["php", "artisan", "serve", "--host=0.0.0.0", "--port=8000"]

With this, although with changes, the app ran but was unable to do much. it kept on giving error:


{
    "code": 500,
    "message": "could not find driver (Connection: storage, SQL: select exists(select * from `role` where `roleid` = 7) as `exists`)"
}

I ran bash inside container and this is what I got when i did php –ini

root@c0c440c243bb:/app# php --ini
PHP Warning:  PHP Startup: Unable to load dynamic library 'mysqli' (tried: /usr/local/lib/php/extensions/no-debug-non-zts-20230831/mysqli (/usr/local/lib/php/extensions/no-debug-non-zts-20230831/mysqli: cannot open shared object file: No such file or directory), /usr/local/lib/php/extensions/no-debug-non-zts-20230831/mysqli.so (/usr/local/lib/php/extensions/no-debug-non-zts-20230831/mysqli.so: cannot open shared object file: No such file or directory)) in Unknown on line 0

Additional .ini files parsed:      /usr/local/etc/php/conf.d/docker-php-ext-sodium.ini

As you can see, it’s not able to access pdo-mysql, although it was defined. infact, there was no php.ini inside container, only php.ini.development and php.ini.production files in /usr/local/etc/php. I cp’ied the php.ini.production to php.ini in the same folder i.e. /usr/local/etc/php but again it didn’t work. and I don’t know if this error is fixed, what other errors would be there.

can anyone help me run the laraval app inside please?

I create a basic dockerfile to run your app you can learn from this.

Dockerfile

FROM php:8.2.0 as php

RUN apt-get update -y
RUN apt-get install -y unzip libpq-dev libcurl4-gnutls-dev
RUN docker-php-ext-install pdo pdo_mysql bc math
RUN pecl install -o -f redis && rm -rf /tmp/pear && docker-php-ext-enable redis

  composer install
