A collection of python libraries for the Validation Framework

The validations will help detect issues early in the deployment process and prevent field engineers from wasting time on misconfiguration or hardware issues in their environments.

Development Environment Setup

Vagrantfiles for CentOS and Ubuntu have been provided for convenience; simply copy one into your desired location and rename to Vagrantfile, then run:

vagrant up

Once complete you will have a clean development environment ready to go for working with Validation Framework.

podman Quickstart

A Dockerfile is provided at the root of the Validations Library project in order to quickly set and hack the Validation Framework, on a equivalent of a single machine. Build the container from the Dockerfile by running:

podman build -t "vf:dockerfile" .

From the validations-libs repo directory.


More complex images are available in the dockerfiles directory and require explicit specification of both build context and the Dockerfile.

Since the podman build uses code sourced from the buildah project to build container images. It is also possible to build an image using:

buildah bud -t "vf:dockerfile" .

Then you can run the container and start to run some builtin Validations:

podman run -ti vf:dockerfile /bin/bash

Then run validations:

validation.py run --validation check-ftype,512e --inventory /etc/ansible/hosts

Skip list

You can provide a file with a list of Validations to skip via the run command:

validation.py run --validation check-ftype,512e --inventory /etc/ansible/hosts --skiplist my-skip-list.yaml

This file should be formed as:

  hosts: targeted_hostname
  reason: reason to ignore the file
  lp: bug number

The framework will skip the validation against the hosts key. In order to skip the validation on every hosts, you can set all value such as:

hosts: all

If no hosts key is provided for a given validation, it will be considered as hosts: all.


The reason and lp key are for tracking and documentation purposes, the framework won't use those keys.
