Automation and ansible
0 likes196 views
Ansible is an open source automation tool that allows users to easily configure, deploy, and manage applications and infrastructure. It uses an agentless architecture and simple YAML files called playbooks to automate tasks across multiple servers. Playbooks define variables, tasks, and templates to configure systems. Roles can be used to organize and reuse playbooks. Jinja2 templates allow dynamic configuration of files and applications.
