ronaldschouw/hello-openshift repository overview

⁠Hello Openshift Container runs on port 8080

Example PHP-FPM 7.3 & Nginx 1.18 setup for Docker, build on Alpine Linux⁠. The image is only +/- 35MB large.

• Built on the lightweight and secure Alpine Linux distribution
• Very small Docker image size (+/-35MB)
• Uses PHP 7.3 for better performance, lower CPU usage & memory footprint
• Optimized for 100 concurrent users
• Optimized to only use resources when there's traffic (by using PHP-FPM's on-demand PM)
• The servers Nginx, PHP-FPM and supervisord run under a non-privileged user (nobody) to make it more secure
• The logs of all the services are redirected to the output of the Docker container (visible with docker logs -f <container name>)
• Follows the KISS principle (Keep It Simple, Stupid) to make it easy to understand and adjust the image to your needs

⁠Usage

Start the Docker container:

docker run -p 80:8080 ronaldschouw/hello-openshift

See the PHP info on http://localhost⁠, or the static html page on http://localhost/test.html⁠

Or mount your own code to be served by PHP-FPM & Nginx

docker run -p 80:8080 -v ~/my-codebase:/var/www/html ronaldschouw/hello-openshift

⁠Configuration

In config/⁠ you'll find the default configuration files for Nginx, PHP and PHP-FPM. If you want to extend or customize that you can do so by mounting a configuration file in the correct folder;

Nginx configuration:

docker run -v "`pwd`/nginx-server.conf:/etc/nginx/conf.d/server.conf" ronaldschouw/hello-openshift

PHP configuration:

docker run -v "`pwd`/php-setting.ini:/etc/php7/conf.d/settings.ini" ronaldschouw/hello-openshift

PHP-FPM configuration:

docker run -v "`pwd`/php-fpm-settings.conf:/etc/php7/php-fpm.d/server.conf" ronaldschouw/hello-openshift

Note; Because -v requires an absolute path I've added pwd in the example to return the absolute path to the current directory

⁠Adding composer

If you need Composer⁠ in your project, here's an easy way to add it.

FROM ronaldschouw/hello-openshift:latest

# Install composer from the official image
COPY --from=composer /usr/bin/composer /usr/bin/composer

# Run composer install to install the dependencies
RUN composer install --optimize-autoloader --no-interaction --no-progress

⁠Building with composer

If you are building an image with source code in it and dependencies managed by composer then the definition can be improved. The dependencies should be retrieved by the composer but the composer itself (/usr/bin/composer) is not necessary to be included in the image.

FROM composer AS composer

# copying the source directory and install the dependencies with composer
COPY <your_directory>/ /app

# run composer install to install the dependencies
RUN composer install \
  --optimize-autoloader \
  --no-interaction \
  --no-progress

# continue stage build with the desired image and copy the source including the
# dependencies downloaded by composer
FROM ronaldschouw/hello-openshift
COPY --chown=nginx --from=composer /app /var/www/html
