Validations-common
.. image:: https://governance.openstack.org/tc/badges/validations-common.svg
:target: https://governance.openstack.org/tc/reference/tags/index.html
.. Change things from this point on
A collection of Ansible roles and playbooks to detect and report potential
issues during deployments.
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.
Installation
Recommended process
There are several different ways to install validations-common.
However it is recommended to both install and use
the package inside python virtual environment.
At the command line using pip
.
.. code-block:: console
$ python3 -m pip install validations-common
Or, if you have virtualenvwrapper_ installed.
.. code-block:: console
$ mkvirtualenv validations-common
$ python3 -m pip install validations-common
Installation with package manager
Alternatively it is possible to install validations-common using package manager.
Such as yum
or dnf
...
.. code-block:: console
$ yum|dnf install validations-common
or the more modern dnf
.
.. code-block:: console
$ dnf install validations-common
Usage
Once the validations-common project has been installed,
navigate to the chosen share path, usually /usr/share/ansible
to access the installed roles, playbooks, and libraries.
While the validations-common can be run by itself,
it nonetheless depends on Ansible and validations-libs.
Therefore it isn't recommended to use only validations-common.

Validations Callbacks
http_json callback
The callback http_json
sends Validations logs and information to an HTTP
server as a JSON format in order to get caught and analysed with external
tools for log parsing (as Fluentd or others).
This callback inherits from validation_json
the format of the logging
remains the same as the other logger that the Validation Framework is using
by default.
To enable this callback, you need to add it to the callback whitelist.
Then you need to export your http server url and port::
export HTTP_JSON_SERVER=http://localhost
export HTTP_JSON_PORT=8989
The callback will post JSON log to the URL provided.
This repository has a simple HTTP server for testing purpose under::
tools/http_server.py
The default host and port are localhost and 8989, feel free to adjust those
values to your needs.
