Introduction to Puppet 5 Configuration and Administration

Introduction to Puppet 5 Configuration and Administration

This Introduction to Puppet 5 Configuration and Administration training teaches participants how to install and administer the Puppet master and agent (client) applications in a RHEL/CentOS 7 environment. Students learn how to write and apply resource definitions, the key part of Puppet that allows an administrator to synchronize environments easily and uniformly.

PUPPET 5 OBJECTIVES

All students will learn to:

• Install and configure Puppet 5 servers and agents
• Create and modify manifests that contain resource definitions
• Create and modify classes, modules, node definitions, and environments
• Apply manifests, classes, nodes, and environments
• Extend Puppet with functions
• Use (and extend) Facter facts
• Generate basic reports
• Use the MCollective and Hiera 5 tools
• Design a ‘best practice’ strategy for using Puppet capabilities

PUPPET 5 PREREQUISITES

It is assumed that participants are working systems administrators with some scripting knowledge (bash, ksh, Perl or Python) and an understanding of the various system tasks relating to setting up and supporting Linux systems.

PUPPET 5 MATERIALS

All students receive Packt’s Puppet 5 Essentials – Third Edition and related courseware.

SOFTWARE NEEDED FOR EACH PC:

Accelebrate would work with you to set up an appropriate virtual environment for this training.

For classes delivered online, all participants need either dual monitors or a separate device logged into the online session so that they can do their work on one screen and watch the instructor on the other. A separate computer connected to a projector or large screen TV would be another way for students to see the instructor’s screen simultaneously with working on their own.
