What is Ansible
Ansible is a configuration management and orchestration tool that is both easy and powerful. Ansible is mostly used for cross-platform computer support automation. It’s primarily aimed at IT pros, who use it for configuration management, cloud provisioning, application deployment, intra-service orchestration, workstation and server updates, and practically everything else a systems administrator does on a daily basis. Ansible is simple to set up since it doesn’t require any agent software or, more critically, any additional specialized security architecture. It employs a simple language (YAML, in the form of Ansible Playbooks) that allows users to describe automation jobs, making it simple to use.
How Ansible works
The control node and managed nodes are the two types of computers in Ansible. The control node is an Ansible-enabled machine. There must be at least one control node, though there may be a backup control node as well. Any device handled by the control node is referred to as a managed node.
Ansible connects to network nodes (clients, servers, or whatever you’re configuring) and sends a little program called an Ansible module to that node. Ansible runs these modules over SSH and removes them once they’re done. The sole stipulation for this interaction is that your Ansible control node has managed node login access. SSH keys are the most frequent method of providing access, however other methods of authentication are also available. SSH keys are the most frequent method of authentication, however alternative methods are also allowed.
Ansible’s architecture
- Controller Machine – A machine that runs Ansible.
- Ansible Tasks – Procedures that Ansible will run.
- Ansible Inventory – Information about the servers to be managed (IP address and alias).
- Ansible Play – Mapping of inventory groups of hosts and tasks to complete.
- Ansible Playbook (Ansible Playbook) (Ansible Playbook) (Ansible The state you want the system to be in is defined. It includes all inventory plays that must be completed.
- Responsible Roles Based on a known file structure, it allows you to load relevant vars files, tasks, and Ansible artefacts automatically. It becomes simple to distribute and reuse your content once you’ve divided it into roles.
- Module – A set of predefined commands that are run on remote hosts.
Benefits of Ansible
- Infrastructure Scaling – when you’re configuring a large number of servers and want to make sure everything is done correctly and quickly.
– Agentless – To work with Ansible, the agent does not need to be installed on the server. It establishes connections with the server using ssh and python.
Modular – It manages configurations using modules, and there are over 750 built-in modules to choose from, making configuration management simple.
- Excellence – It has a low latency, which improves performance.
- Cheap Overheads – There is no need for agents or tools, resulting in significant space savings and low deployment overhead.
- Simple – because it employs Yaml, an English-like language that is simple to grasp.
