Hey there, fellow developers! If you're like me, you've probably struggled with setting up a local development environment that mimics the live server. Enter Docker - a lifesaver that allows us to create, deploy, and run applications in containers. In this blog post, I'll walk you through creating a Docker environment for web development, using Apache, PHP, MySQL, and PhpMyAdmin. Let's dive in!
Why Use Docker?
Docker is not just a buzzword; it's a powerful platform that offers some serious advantages. It gives you portability, efficiency, and consistency, all wrapped in one. If you haven't jumped on the Docker train yet, it's high time you did!
Setting up Apache, PHP, MySQL with Docker Compose
Setting up Apache, PHP, and MySQL with Docker is a breeze. Here's how you can do it:
1. Dockerfile
Let's start by creating a Dockerfile to define the Apache and PHP environment. Here's an example you can use:
##########################################
#
# Dockerfile
#
# See: https://docker.com/
# See: https://docs.docker.com/engine/reference/builder/
#
# Author: prod3v3loper

#
##########################################
FROM php:8.1-apache
# Install system dependencies
RUN apt-get update && apt-get install -y \
nano \
vim \
libfreetype6-dev \
libjpeg62-turbo-dev \
libpng-dev \
&& docker-php-ext-configure gd --with-freetype --with-jpeg \
&& docker-php-ext-install -j$(nproc) gd
# Install PHP extensions
RUN docker-php-ext-install pdo pdo_mysql mysqli && docker-php-ext-enable mysqli
# Copy files to container htdocs
COPY /var/www /var/www/html/
# Set working directory
WORKDIR /var/www/html/
# NPM actions
# RUN npm install --production
# COMPOSER actions
# COPY --from=composer:latest /usr/bin/composer /usr/bin/composer
RUN a2enmod rewrite
CMD ["/usr/sbin/apache2ctl", "-D", "FOREGROUND"]2. docker-compose.yml
Next, you'll need to define and run your services using a docker-compose.yml file. Here's an example:

Now, all you need to do is run docker-compose up, and you'll have your environment ready to go!
Working with PhpMyAdmin
PhpMyAdmin is a handy tool that lets you manage your databases through a web interface. It's a must-have in any developer's toolkit.
Managing Containers
Docker provides some nifty commands that make managing your containers a piece of cake. Here are a few examples:
- Start Containers: docker-compose up
- Stop Containers: docker-compose down
- Access Container Shell: docker exec -it <container_name> /bin/bash
Conclusion
And there you have it! With Docker, setting up a development environment has never been easier. I hope you found this guide helpful. Feel free to check out the complete code on GitHub - prod3v3loper docker.
Happy coding!
