Describe your experience with container technologies in projects.

In PHP projects, I used Docker for containerizing applications. This allowed creating isolated environments with the required PHP versions, extensions, and dependencies, which simplified deployment and testing. For example, using Docker Compose, I would run a stack of PHP-FPM, Nginx, and databases in separate containers, ensuring stability and reproducibility of the environment.

A simple Dockerfile for PHP:

FROM php:8.1-fpm
RUN docker-php-ext-install pdo pdo_mysql
COPY . /var/www/html
