Ansible

A series of articles about configuration managment at the example of Ansible.

By using a configuration management tool, the procedure necessary for bringing up a new server or updating an existing one will be all documented in the provisioning scripts.

Terms

  • Inventory stores information about your servers as INI file

  • Role is used to organize playbooks and other files for reuse

  • Facts are variables containing information about the system, e.g. OS, hostname etc.
  • Handlers trigger service status changes
