Ansible can interact with clients through either command line tools or through its configuration scripts called Playbooks. Configuration files are mainly written in the YAML data serialization format due to its expressive nature and its similarity to popular markup languages. Modules can be written in any language and communicated in standard JSON. Any server that has an SSH port exposed can be brought under Ansible’s configuration umbrella, regardless of what stage it is at in its life cycle.Īnsible takes on a modular approach, making it possible to use the functionalities of the main system to deal with specific scenarios. This is one way that Ansible facilitates the administration of servers. Because of this, an Ansible system does not require any additional software to be installed on the client computers. It communicates over normal SSH channels to retrieve information from remote machines, issue commands, and copy files. Ansible is a great alternative to these options because it has a much smaller overhead to get started.Īnsible works by configuring client machines from a computer with Ansible components installed and configured. While there are many popular configuration management systems available for Linux systems, such as Chef and Puppet, these are often more complex than many people want or need. They allow you to control many different systems in an automated way from one central location. Configuration management systems are designed to make controlling large numbers of servers accessible for administrators and operations teams.
