What is the 12-Factor App methodology?

It is a set of 12 foundational principles for building software-as-a-service (SaaS) applications that are scalable, maintainable, and easily portable between different cloud environments.

Which programming languages are supported?

The methodology is language-agnostic, and this skill includes examples for popular environments including Node.js, Python, Elixir, Go, Java, and Rust.

Can this skill help with legacy code migration?

Yes, it can identify common anti-patterns such as hardcoded configurations or local file dependencies and suggest modern, stateless alternatives.

Does it cover CI/CD practices?

Yes, it provides guidance on Factor V (Build, Release, Run), emphasizing the strict separation of stages to ensure immutable and reproducible deployments.

How does this skill assist with Kubernetes deployments?

The skill provides specific YAML patterns for ConfigMaps, Secrets, Horizontal Pod Autoscalers, and lifecycle hooks that align with cloud-native best practices.
