DevOps Foundations: Your First Project

Course details

Curious about how to put DevOps principles into practice? This course can help. Join instructor and DevOps expert Carlos Nunez as he demonstrates how to apply DevOps principles to a sample app for a fictitious travel booking company. Throughout the course, Carlos shows you how to leverage popular tools and methodologies to make updating, testing, and releasing the app a breeze. After explaining how to containerize the website with Docker and Docker Compose, he shows how to write unit and integration tests with RSpec, Capybara, and Selenium. He then guides you through the process of deploying your website to the cloud with OpenTofu and using GitLab CI, GitLab's built-in CI/CD service that can build, test, and deploy your app. Upon completing this course, you'll know how to turn a slow and complex application development process into a fast and enjoyable one.
