Ansible for network engineers

Description

The course focusses on the use of ansible for network
devices instead of its usual server use case. The
course progresses from the basics of ansible and
playbooks onto using network specific modules
including NAPALM. The use Jinja2 templating with
ansible is also studied. Hands on sessions with ansible
configuring routers and switches follow all major
sections.
