Ansible with-junos
Ansible can be used to deploy the same configuration to multiple network devices with a single playbook. YAML is used to define variables, hosts, roles, tasks and other elements. For example, a playbook is shown that uses the Juniper.junos role to load and merge a configuration file to switches, prompting for username and password and checking the connection before installing the configuration. The playbook also saves configuration diffs and logs of the process.

- 4. Work Environment • Platformon tested: Juniper router and switches • List target hosts on /etc/ansible/hosts • Roles saved in /etc/ansible/roles/ • Run on CLI: • Ansible-playbook junos-install-config.yml • Further, Ansible uses “{{ var }}” for variables. If a value after a colon starts with a “{”, YAML will think it is a dictionary, so you must quote it, like so: /etc/ansible/hosts
