Earthly is a newly introduced build automation tool designed to modernize the continuous integration and delivery landscape by leveraging containerization and parallelization capabilities. Unlike traditional CI systems that resemble bash scripts, Earthly enhances existing open-source tools like Gradle, Maven, npm, and webpack without requiring users to overhaul their build configurations. It provides container isolation for build targets, ensuring reproducibility and eliminating race conditions, while using a Dockerfile-like syntax for ease of use. Earthly not only supports the creation of Docker images but also outputs regular artifacts, making it versatile for different build requirements. The tool is geared for both local development and integration with existing CI systems, with future plans to offer cloud-based build parallelization and additional enhancements based on user feedback.
