Ansible is a powerful open-source automation tool that helps you automate IT infrastructure and application deployment. It is written in Python and is agentless, meaning it doesn't require any software to be installed on the machines you want to manage. Ansible uses a simple YAML-based language to define the desired state of your systems, and then it automatically takes the necessary steps to achieve that state.
Ansible requires a Control Node that connects with the managed hosts thought ssh to make the desired changes. Installation is done in the Control Node and this node installs the needed packages in the managed hosts when needed.
How to install Ansible on Ubuntu
The Ansible Control Node is the central machine within an Ansible environment responsible for executing automation tasks on managed hosts. It acts as the brains of the operation, housing the Ansible software and managing the communication and execution of playbooks.
To install follow the official installation instructions or run the following apt commands for installation on Ubuntu.
$ sudo apt-add-repository ppa:ansible/ansible $ sudo apt update $ sudo apt install ansible
Check that the Ansible has been installed.
$ ansible --version ansible [core 2.16.1] config file = /etc/ansible/ansible.cfg configured module search path = ['/home/user/.ansible/plugins/modules', '/usr/share/ansible/plugins/modules'] ansible python module location = /home/user/.local/lib/python3.10/site-packages/ansible ansible collection location = /home/user/.ansible/collections:/usr/share/ansible/collections executable location = /usr/bin/ansible python version = 3.10.12 (main, Nov 20 2023, 15:14:05) [GCC 11.4.0] (/usr/bin/python3) jinja version = 3.0.3 libyaml = True
