The four-day AJAUT course gives students a hands-on experience with DevOps, and infrastructure as code (IaC) with devices running the Junos OS. Students will learn the tools needed to operate an open-source DevOps environment. Specifically, students will learn to use Docker, GitLab, Ansible, The Robot Framework, and Jenkins. While learning the tools, students will utilize the tools to build a working DevOps project using two Juniper vMX devices.

Intended Audience

This course benefits individuals responsible for configuring, monitoring, and automating devices running the Junos OS.

Prerequisites

Students should have taken the Junos Platform Automation (JAUT) course or have equivalent knowledge.
