TripleO is a collection of OpenStack tools used to deploy a fully functional OpenStack from a minimal OpenStack installation. It leverages tools like Heat, DiskImage Builder, and os-collect-config. DiskImage Builder is used to generate customized virtual machine images with preinstalled packages and configuration templates. Heat templates are then used to deploy the infrastructure using these images and populate configuration files using the templates. This reduces deployment time and complexity compared to traditional configuration management approaches.
