Ansible Modules for Arista CloudVision Platform

About

Arista Networks supports Ansible for managing devices running the EOS operating system through CloudVision platform (CVP). This collection includes a set of ansible modules that perform specific configuration tasks on CVP server. These tasks include: collecting facts, managing configlets, building topology with containers and devices, running tasks.

Arista CloudVision and Ansible

Even if arista.cvp collection is integrated with arista.avd collection to automate configuration deployment, this collection can also be used outside of AVD tasks to populate your Cloudvision server with your own workflows.

Requirements

Arista CloudVision

Current active branch:

Info

Starting version 2.0.0, collection uses cvprac as Cloudvision connection manager. So support for any new CLoudvision server is tied to it support in this python library.

ansible-cvp 1.0.0 1.1.0 >= 2.0.0
2018.2
2019.x
2020.1
>= 2020.2
Python
  • Python >=3.8

Please check the minimum version supported by your ansible installation on ansible website

Additional Python Libraries required

Ansible version:

  • ansible >= 2.9.0

3rd party Python libraries:

  • cvprac
  • requests
  • jsonschema
  • treelib (for modules in version 1)
netaddr>=0.7.19
Jinja2>=2.10.3
paramiko>=2.7.1
requests>=2.22.0
cvprac>=1.0.7

treelib>=1.5.5

Installation

pip install ansible_collections/arista/cvp/requirements.txt

# For modules in version 1
pip install treelib>=1.5.5

Ansible galaxy hosts all stable version of this collection. Installation from ansible-galaxy is the most convenient approach for consuming arista.cvp content

$ ansible-galaxy collection install arista.cvp
Process install dependency map
Starting collection install process
Installing 'arista.cvp:1.1.0' to '~/.ansible/collections/ansible_collections/arista/cvp'

Complete installation process is available on repository website

Example

This example outlines how to use arista.cvp to create a containers topology on Arista CloudVision.

A dedicated repository is available for step by step examples on ansible-cvp-toi.

A complete end to end demo using Arista Validated Design collection and CloudVision modules is available as an example.

Below is a very basic example to build a container topology on a CloudVision platform assuming you have 3 veos named veos0{1,3} and a configlet named alias
