PyInfra: Because Your Infrastructure Deserves Real Code in Python, Not YAML Soup by Loïc Tosser "wowi42"

Because Your Infrastructure Deserves Real Code in Python, Not YAML Soup

Abstract

Remember when we said "Infrastructure as Code"? Somehow, the industry heard "Infrastructure as YAML" and ran with it. This talk promotes PyInfra as a Python-based alternative for infrastructure automation with real code, IDE support, proper debugging, and testing with pytest.

Description

Remember when we said "Infrastructure as Code"? Somehow, the industry heard "Infrastructure as YAML" and ran with it.

This presentation critiques YAML-based infrastructure tools and promotes PyInfra as a Python-based alternative. Key topics covered include:

• Writing infrastructure automation with real Python code and IDE support
• Debugging with proper stack traces instead of cryptic error messages
• Using native Python conditionals rather than complex DSL syntax
• Importing and reusing code like standard software development
• Testing infrastructure with pytest instead of staging environments

The talk demonstrates converting a 500-line Ansible playbook into 50 lines of maintainable Python code, highlighting benefits like list comprehensions and actual logic capabilities.
