GitHub Actions Dynamic Matrix

GitHub Actions is a powerful CI/CD tool that allows you to automate your software development workflow. It provides a wide range of features and capabilities.

One of the features that I found very useful is the ability to define a matrix strategy for your jobs. This allows you to run the same job with different parameters, such as different versions of a programming language.

However, there are times when you need to define the matrix dynamically based on the output of a previous job. For example, you may want to run a job for each directory if and only if the directory contains a specific file or has changed since the last commit.

In this post, I will show you how to define a dynamic strategy matrix in GitHub Actions using a real-world example.
