Junos modules for Ansible

ABOUT

Juniper Networks provides support for using Ansible to deploy devices running the Junos operating system (Junos OS). The Juniper Networks Ansible library, which is hosted on the Ansible Galaxy website under the role junos, enables you to use Ansible to perform specific operational and configuration tasks on devices running Junos OS, including installing and upgrading Junos OS, deploying specific devices in the network, loading configuration changes, retrieving information, and resetting, rebooting, or shutting down managed devices. Please refer to INSTALLATION section for setup.

In addition to these modules, Since 2.1, Ansible natively include some core modules for Junos. Both Core and Galaxy modules can cohexist on the same platform.

OVERVIEW OF MODULES

• junos_get_facts — Retrieve device-specific information from the host.
• junos_commit — Commit candidate configuration on device.
• junos_get_config — Retrieve configuration of device.
• junos_install_config — Modify the configuration of a device running Junos OS.
• junos_install_os — Install a Junos OS software package.
• junos_rollback — Rollback configuration of device.
• junos_shutdown — Shut down or reboot a device running Junos OS.
• junos_srx_cluster — Enable/Disable cluster mode for SRX devices
• junos_zeroize — Remove all configuration information on the Routing Engines and reset all key values on a device.
• junos_get_table - Retrieve data from a Junos device using Tables/Views
• junos_ping - execute ping on junos devices
• junos_jsnapy - Integrate JSNAPy to ansible which helps audit network devices
• junos_rpc — To execute RPC on device and save output locally
• junos_cli — To execute CLI on device and save output locally

OVERVIEW OF PLUGINS

In addition to the modules listed above, a callback_plugin jsnapy is available for the module junos_jsnapy.

The callback_plugin jsnapy helps to print on the screen additional information regarding jsnapy failed tests. For each failed test, a log will be printed after the RECAP of the playbook.

The plugin jsnapy is currently in Experimental stage, please provide feedback.

INSTALLATION

This repo assumes you have the DEPENDENCIES installed on your system.

Ansible Galaxy Role

To download the junos role to the Ansible server, execute the ansible-galaxy install command, and specify Juniper.junos.

[root@ansible-cm]# ansible-galaxy install Juniper.junos
- downloading role 'junos', owned by Juniper
- downloading role from https://github.com/Juniper/ansible-junos-stdlib/archive/1.3.1.tar.gz
- extracting Juniper.junos to /usr/local/etc/ansible/roles/Juniper.junos
- Juniper.junos was installed successfully

Git clone

For testing you can git clone this repo and run the env-setup script in the repo directory:

user@ansible-junos-stdlib> source env-setup

This will set your $ANSIBLE_LIBRARY variable to the repo location and the installed Ansible library path. For example:

[jeremy@ansible-junos-stdlib]$ echo $ANSIBLE_LIBRARY
/home/jeremy/Ansible/ansible-junos-stdlib/library:/usr/share/ansible

Example Playbook

This example outlines how to use Ansible to install or upgrade the software image on a device running Junos OS.
