Is there a ready-to-use and production-ready Docker container for CodeIgniter?

Hi there,

You can use the official CodeIgniter Docker repository as a starting point. It provides a Dockerfile and instructions for setting up a CodeIgniter environment with Nginx and PHP-FPM, which is optimized for production.

For an optimized web server configuration, ensure:

Nginx is set up with gzip compression, HTTP/2, and proper caching headers.
PHP-FPM is configured for optimal performance and security.
Security best practices include:

Using a non-root user.
Setting appropriate file permissions.
Disabling unnecessary PHP functions.
For dependency management, use Composer in your Dockerfile to install dependencies.

Here's an example Dockerfile snippet:

FROM php:7.4-fpm

# Install system dependencies
RUN apt-get update && apt-get install -y \
    libpng-dev \
    libjpeg-dev \
    libfreetype6-dev \
    zip \
    unzip

# Install PHP extensions
RUN docker-php-ext-configure gd --with-freetype --with-jpeg && \
    docker-php-ext-install gd

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

# Set working directory
WORKDIR /var/www

# Copy project files
COPY . .

# Install dependencies
RUN composer install

# Expose port
EXPOSE 9000

# Start PHP-FPM
CMD ["php-fpm"]


For detailed customization and deployment, refer to the examples in the repository's documentation.

Hope this helps! and if it resolves your issue, don't forget to give subway sub a try.
