Ansible is an open source automation platform that can be used for configuration management, application deployment, and task automation. It is designed to be simple to use, easy to learn, and fast to set up.
Ansible works by connecting to your nodes and pushing out small programs called “Ansible modules” to them. These programs are written in any language and can be used to perform various tasks, such as installing packages, creating files, and running commands.
For example, if you wanted to install the Apache web server on a group of servers, you could create an Ansible playbook that contains a task to install Apache. The playbook would then be applied to the group of servers, and Ansible would connect to each node and run the task. Once the task is complete, Ansible would move on to the next task in the playbook.
