Welcome to YAOOK.

The Lifecycle Management Tool for OpenStack and SecuStack.

The project.

Scope of YAOOK.

Yaook is an important step towards more digital sovereignty. It renders it possible to deploy and operate own Cloud infrastructures based on Open Source. For this purpose, Yaook is providing a fully automated and free OpenStack Lifecycle Management (LCM). In this context, it does not only focus on provisioning OpenStack itself, but also on all other aspects relevant for managing OpenStack-based infrastructures (e.g. hardware inventory, monitoring). Generic day 2 operation tasks are natively included in Yaook’s scope.

Open Source.


YAOOK Bare Metal

Deploys and manages server hardware (“Metal-as-a-Service”). This includes defining and building the operating system running on the servers as well as their network and disk configuration. It allows to automatically redeploy nodes, which is our primary mechanism for software updates.

YAOOK Kubernetes

Deploys and manages the Kubernetes below OpenStack. It handles Kubernetes upgrades transparently and provides a full-featured Kubernetes cluster with LoadBalancers, Ingresses, StorageClasses, Certificates and further relevant pieces.

YAOOK Operator

Deploys and manages OpenStack on top of Kubernetes. It talks to the standard Kubernetes APIs to create and manage resources in the cluster. It handles OpenStack upgrades and maintenance (such as evacuating nodes) and provides an interface for the user to insert configuration.
