Ansible in 100 Seconds

Ansible is a popular configuration management tool created by Michael Dahan in 2012 and later acquired by Red Hat. It uses declarative YAML code to automate Linux server management, reducing human error. Ansible operates with a control node that connects to managed nodes via SSH, executing tasks defined in playbooks. Playbooks are item potent, ensuring changes are only made when necessary. A practical application is managing Linux servers on Lenode, where Ansible can be installed on a control node to automate server provisioning. Ansible Galaxy offers a vast ecosystem of prebuilt playbooks, and Vault can be used to securely store sensitive information. Creating a playbook involves defining tasks and configurations, which can be executed to automate infrastructure management.
