Résumé du cours
The three-day AJAUT course gives students 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. Students will learn and utilize the tools to build a working DevOps project using two Juniper vMX devices.
This course uses Junos OS Release 17.3R1, PyEZ 2.1, Python 2.7, Git 2.17, and Ansible 2.4.
Advanced Junos Platform Automation and DevOps (AJAUT) is an advanced-level course.
