# Installation using Ansible

{% hint style="info" %}
The [Ansible collection for NetObserv](https://galaxy.ansible.com/ui/repo/published/elastiflow/netobserv/docs/) is currently a *technology preview*. The design and implementation are less mature than stable features and subject to change. Please provide feedback or report issues to the [ElastiFlow Forum](https://forum.elastiflow.com/). 
{% endhint %}

An ansible role is available to install and configure NetObserv Flow. The role is available via the [Ansible Galaxy role](https://galaxy.ansible.com/ui/repo/published/elastiflow/netobserv/content/role/netobserv_flow/).

### Requirements

* Ansible 2.16 or later
* Python 3.10 or later
* A target host running a supported version of Linux. For more information on available distributions and versions, see the [NetObserv Collection Requirements](https://github.com/elastiflow/ansible-collection-netobserv?tab=readme-ov-file#requirements).

### Example Playbooks

Here are the examples of how to use the `elastiflow.netobserv.netobserv_flow` role:
