What is Ansible?

Ansible is an open-source software platform that enables infrastructure as code (IaC) and automates deployment, configuration management, and application deployment. It is designed to simplify the process of managing complex IT environments by providing a simple, agentless, and extensible framework for automating tasks.

Main Features

Ansible provides a range of features that make it a popular choice for automation and configuration management, including:

• Agentless architecture: Ansible does not require any agents to be installed on the target machines, making it easier to manage and maintain.
• Playbooks: Ansible uses playbooks, which are YAML files that define the desired state of the infrastructure, to automate tasks.
• Modules: Ansible has a vast collection of modules that provide a wide range of functionality, from managing users and groups to configuring network devices.

Ansible Snapshot and Restore Workflow

What is a Snapshot?

A snapshot is a point-in-time copy of a virtual machine or a set of virtual machines. Ansible provides a snapshot module that allows you to create and manage snapshots of your virtual machines.

How to Create a Snapshot

To create a snapshot using Ansible, you will need to create a playbook that uses the snapshot module. Here is an example of how you might do this:

---
- name: Create a snapshot
  hosts: my_vm
  tasks:
    - name: Create a snapshot
      snapshot:
        name: my_snapshot
        state: present
