Ansible is fun, you saw in last few days how easy it is.

Let's make it fun now, by using a video explanation for Ansible.

Task-01

Ansible is an open-source automation tool that provides a simple yet powerful framework for automating IT tasks. It is designed to streamline the process of configuring and managing systems, deploying applications, and orchestrating complex tasks across a network of computers. Ansible uses declarative language to describe the desired state of a system, allowing users to define the desired configuration and let Ansible handle the execution details.

Key features of Ansible include:

  1. Agentless architecture: Ansible uses SSH (Secure Shell) and other standard protocols to connect to remote systems, eliminating the need for agents or additional software to be installed on the managed machines.

  2. Playbooks: Ansible configurations are defined in YAML files called playbooks. Playbooks describe the desired state of a system and specify the tasks that should be executed to achieve that state.

  3. Idempotence: Ansible ensures idempotent execution, meaning that running the same playbook multiple times will not cause unwanted side effects. It checks the current state of the system and only performs necessary actions to bring it to the desired state.

  4. Inventory: Ansible maintains an inventory file that lists the target hosts or groups of hosts on which operations should be performed. This inventory can be dynamic and updated as needed.

  5. Modules: Ansible provides a vast library of modules that can be used to perform specific tasks on managed systems. Modules can manage files, install packages, configure services, interact with cloud platforms, and more.

  6. Ad-hoc commands: In addition to playbooks, Ansible allows for the execution of ad-hoc commands for quick tasks or troubleshooting. These commands can be run against selected hosts or groups.

Ansible is known for its simplicity, ease of use, and scalability. It is widely used for configuration management, application deployment, and infrastructure automation in both small and large-scale environments.

happy Learning :)
