Install DevStack and Tacker in DevStack


  • DevStack is a set of scripts and utilities to quickly deploy an OpenStack cloud from git source trees.
  • It can also be used to demonstrate starting/running OpenStack services and provide examples of using them from a command line.
  • It should not deploy as a production.

Tacker is an official OpenStack project building a Generic VNF Manager (VNFM) and a NFV Orchestrator (NFVO) to deploy and operate Network Services and Virtual Network Functions (VNFs) on an NFV infrastructure platform like OpenStack. It is based on ETSI MANO Architectural Framework and provides a functional stack to Orchestrate Network Services end-to-end using VNFs.
