Implementación de un pipeline de CICD utilizando GitHub Actions para optimizar el proceso de integración y despliegue continuo de aplicaciones en la nube

Abstract

Abstract: This work proposed to implement a complete continuous integration and deployment pipeline (CI/CD) using Github Actions to optimize the development process and cloud apps deployment. The main objective was to demonstrate how CI/CD practices can automate and significantly improve building processes, testing, linting and web apps deployment. The specific objectives included to investigate the best CI/CD practices, configuring an automated pipeline that integrates testing and linting tools, Github Actions performance evaluation and making a comparison with similar tools like Jenkins and Gitlab CI to determine the pros and cons of each platform. To achieve the objectives, a case study was developed by using as base project React TodoMVC app, implementing a full Github Actions pipeline that executes five main jobs: build, lint, tests, end-to-end tests and deployment. ESLint and Prettier for linting, Jest and Cypres for unit tests and end-to-end tests correspondingly, were some of the tools used on this methodology. The pipeline was configured with job interdependence, guaranteeing that only validated code reaches production environments, deploying automatically the web app in AWS S3 in static hosting mode configuration. Best practices as secrets for credentials, IAM permissions policies and artifacts to shared compiled code were implemented in all the pipeline jobs.
