Students will start this course by installing Puppet Enterprise. They will then learn Puppet best practices and use Puppet to write simple classes. Students will learn how to update and extend existing modules. The practitioner will be taught through a combination of lecture and relevant, real-world, hands-on exercises. After completing this course, students will be able to deploy basic system configurations using best practices for Puppet in a Master-Agent setup.
After completing this course, students will show a mastery of the Puppet DSL and common design patterns, providing them with solutions and problem-solving techniques along with a better understanding of Puppet best practices.
