WordPress Docker Container

Lightweight WordPress container with Nginx 1.22 & PHP-FPM 8.0 based on Alpine Linux.

WordPress version currently installed: 6.0.2

• Used in production for many sites, making it stable, tested and up-to-date
• Optimized for 100 concurrent users
• Optimized to only use resources when there's traffic (by using PHP-FPM's ondemand PM)
• Works with Amazon Cloudfront or CloudFlare as SSL terminator and CDN
• Multi-platform, supporting AMD4, ARMv6, ARMv7, ARM64
• Built on the lightweight Alpine Linux distribution
• Small Docker image size (+/-90MB)
• Uses PHP 8.0 for better performance, lower cpu usage & memory footprint
• Can safely be updated without losing data
• Fully configurable because wp-config.php uses the environment variables you can pass as an argument to the container

I can help you with Containerization, Kubernetes, Monitoring, Infrastructure as Code and other DevOps challenges.
