Juniper JAUT - Junos Platform Automation and DevOps

Résumé du cours

This five-day course provides students with knowledge of how to automate Junos using DevOps automation tools, protocols, and technologies. Students receive hands-on experience with tools and languages relevant to automating the Junos OS platform in a DevOps environment. The course includes introduction to Jinja2 templates, an in-depth discussion of Junos PyEZ library, and detailed explanation of how Ansible, Salt and JSNAPy automation tools are used with Junos. The course introduces students to Junos commit, operation (op), event, and SNMP on-box scripts. Two languages for developing these scripts are discussed: SLAX and Python. The course also explains Juniper Extension Toolkit and related APIs, YANG and OpenConfig. Finally, the course discusses the use of Junos Telemetry Interface and Contrail HealthBot tool, and Junos ZTP feature. Through demonstrations and hands-on labs, students will gain experience in automating the Junos operating system and device operations.

This course uses Junos OS Release 18.3R1, Junos PyEZ 2.2, and Ansible 2.7.
