During the "Intro to Codefresh YAML" webinar, led by Codefresh Senior Backend Engineer Noam Tenne, participants learned how to work with YAML files to customize their build environment and pipelines. The session covered the structure and benefits of YAML-based configurations, illustrating how these files enable more flexible and advanced customization options compared to the user interface, particularly for complex tasks. Through a live demonstration, Noam showcased how to write a simple YAML file to test code, build a Docker image, and push it to Docker Hub or any registry, emphasizing the ability to automate and manage complete build, test, and deploy pipelines. The webinar highlighted the advantages of using YAML files for detailed configuration, allowing for an unlimited number of steps, integration with external services, and comprehensive customization of the development workflow.
