Ansible Interview Questions and Answers
Ansible is a free and open source-software platform for configuring and managing computers, combines multi-node software deployment, ad hoc task execution, configuration management, provisioning, Security and Compliance. It manages nodes over SSH or over PowerShell. Modules work over JSON and standard output and can be written in any programming language. The system uses YAML to express reusable descriptions of systems. It aims to provide large productivity gains to a wide variety of automation challenges.
Unlike Puppet or Chef, Ansible operates without requiring an agent on the remote host. Instead, it leverages SSH, assuming it’s installed on all managed systems. Additionally, Ansible is scripted in Python, necessitating Python installation on the remote host.
This eliminates the need for a client-server setup before deploying Ansible, allowing execution from any machine. From the client’s perspective, there’s no awareness of an Ansible server (in contrast to Puppet’s standalone mode, which still demands Puppet installation). Certain prerequisites exist, like the requirement for a Git package on a remote machine for Git-related tasks.
Ansible is freely available and compatible with Linux, Mac, or BSD systems. Besides its open-source version, Ansible offers an enterprise-grade product named Ansible Tower.
Ansible tool is very simple to use yet powerful enough to automate complex multi-tier IT application environments.
Michael DeHaan, the author of the provisioning server application Cobbler and co-author of the Func framework for remote administration, developed the platform. Ansible, Inc. was the company set up to commercially support and sponsor Ansible. Red Hat acquired Ansible in October 2015.
