Infrastructure automation is a cornerstone of modern DevOps. Ansible is a powerful, agentless tool for automating server provisioning, configuration, and application deployment.

Why Ansible?

  • Agentless: Uses SSH, no agent required on managed nodes.
  • Idempotent: Ensures repeatable, predictable results.
  • Modular: Roles and playbooks promote reuse.

Example: Provisioning a Web Server

- hosts: webservers
  become: yes
  roles:
    - nginx

Best Practices

  • Use roles for modularity.
  • Store secrets in Ansible Vault.
  • Test playbooks with Molecule.
  • Use dynamic inventory for cloud environments.

Security Tips

  • Use SSH keys, not passwords.
  • Limit privilege escalation.
  • Audit playbook changes.
