Should we not use something like

FROM php:7.3-fpm

# Update packages and install composer and PHP dependencies.
RUN apt-get update && \
  DEBIAN_FRONTEND=noninteractive apt-get install -y \
    postgresql-client \
    libpq-dev \

    libmcrypt-dev \
    libpng12-dev \
    libbz2-dev \
    cron \
    && pecl channel-update pecl.php.net \
    && pecl install apcu

# PHP Extensions
RUN docker-php-ext-install mcrypt zip bz2 mbstring pdo pdo_pgsql pdo_mysql pcntl \
&& docker-php-ext-configure gd --with-freetype-dir=/usr/include/ --with-jpeg-dir=/usr/include/ \

# Memory Limit
RUN echo "memory_limit=2048M" > $PHP_INI_DIR/conf.d/memory-limit.ini
RUN echo "max_execution_time=900" >> $PHP_INI_DIR/conf.d/memory-limit.ini
RUN echo "extension=apcu.so" > $PHP_INI_DIR/conf.d/apcu.ini
RUN echo "post_max_size=20M" >> $PHP_INI_DIR/conf.d/memory-limit.ini
RUN echo "upload_max_filesize=20M" >> $PHP_INI_DIR/conf.d/memory-limit.ini

# Time Zone
RUN echo "date.timezone=${PHP_TIMEZONE:-UTC}" > $PHP_INI_DIR/conf.d/date_timezone.ini

# Display errors in stderr
RUN echo "display_errors=stderr" > $PHP_INI_DIR/conf.d/display-errors.ini

# Disable PathInfo
RUN echo "cgi.fix_pathinfo=0" > $PHP_INI_DIR/conf.d/path-info.ini

# Disable expose PHP
RUN echo "expose_php=0" > $PHP_INI_DIR/conf.d/path-info.ini

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

ADD . /var/www/html
WORKDIR /var/www/html

RUN mkdir storage/logs
RUN touch storage/logs/laravel.log

RUN composer install
#RUN php artisan cache:clear
#RUN php artisan view:clear
#RUN php artisan route:cache

RUN chmod -R 777 /var/www/html/storage

RUN touch /var/log/cron.log

ADD deploy/cron/artisan-schedule-run /etc/cron.d/artisan-schedule-run
RUN chmod 0644 /etc/cron.d/artisan-schedule-run
RUN chmod +x /etc/cron.d/artisan-schedule-run
RUN touch /var/log/cron.log

CMD ["/bin/sh", "-c", "php-fpm -D | tail -f storage/logs/laravel.log"]

like used by Li0nel https://github.com/li0nel/laravel-terraform/blob/master/Dockerfile so we can add PHP FPM with needed extensions, composer, memory limit and so on . Did check https://hub.docker.com/r/hirenkavad/laravel-k8 but cannot see what it contains nor is a Github repo attached to it..

Also

docker pull hirenkavad/laravel-k8
Using default tag: latest
Error response from daemon: manifest for hirenkavad/laravel-k8:latest not found: manifest unknown: manifest unknown

So did have to pick a version

Error response from daemon: manifest for hirenkavad/laravel-k8:latest not found: manifest unknown: manifest unknown

Also, creating a Dockerfile from an image is a pain ... https://stackoverflow.com/questions/19104847/how-to-generate-a-dockerfile-from-an-image

Realized that you need to connect your Docker Hub repo to Github and build to load the README.mdand Dockerfile. I did now and have my first Laravel App image here https://hub.docker.com/r/smart48/laravel-app/dockerfile. Only tagging did not work so I also only have the latest now. But will work that out as well I am sure.

The question is how source code appears in busybox image to copy in mounted /code directory. It doesn't have "/var/www/." directory.

If you could share your updated code that would be great for all @faridmmv . Thanks in advance for your contribution!
