Git and GitLab Essentials

This course covers the fundamentals necessary to utilize Git and GitLab for the management of software development lifecycling using continuous integration and continuous delivery (CI/CD).  At its core, GitLab offers a web-based Git repository manager featuring issue tracking, analytics, and a wiki. Within the suite includes tools to trigger builds, run tests, and deploy code with each commit or push. Builds can target Docker containers or Virtual Machines. GitLab’s ability to offer a DevOps platform in a single application makes it an attractive choice for enterprise users.

What You’ll Learn

By the conclusion of this course, attendees will learn how to use Git and GitLab to view, create, and manage code, as well as the role GitLab can play in automating builds and shortening release of applications. This includes hands-on labs learning how to check in code, including Python, Java, and GoLang applications. Practice team collaboration methods for projects and advancing code. Leave with an understanding of how Git and GitLab can fully automate the entire DevOps life cycle, from planning through to creation, build, verification, security testing, deployment to production environments, such as Kubernetes, and monitoring.
