Spotlight on… Zuul

Zuul, a pilot project supported by the OpenStack Foundation (OSF), is a suite of free/libre open source software that drives continuous integration, delivery and deployment (CI/CD) with a focus on project gating and coordinating changes across interrelated projects.

Zuul tests cross-project changes in parallel so users can easily validate changes to multiple systems together before landing a single patch.

Since 2012, Zuul has been proven at scale as a critical part of the OpenStack development process. In early 2018, version 3 was released and Zuul became an independently-governed effort, distinct from the OpenStack project. The third major release also marked a significant rewrite to improve general re-usability of Zuul outside of the OpenStack project and has seen adoption in organizations like BMW, leboncoin, GoDaddy and OpenLab. Many of Zuul’s users are also contributors, with development coming from the likes of Red Hat, BMW, GoDaddy, Huawei, GitHub and the OSF.

Zuul now supports code management through connection drivers for Gerrit, GitHub and generic Git remote repositories, with work underway to add Pagure. Since Zuul relies on Ansible for job definition language, it can run builds on any operating system that Ansible can manage. Zuul’s resource pool manager, Nodepool, can manage workloads on resources dynamically provisioned through APIs for OpenStack and Kubernetes, or on separately-maintained “static” servers and is working to add Red Hat OpenShift, Amazon Elastic Compute Cloud (AWS EC2), Microsoft Azure and VMware vSphere support to that list. Major Zuul design discussions currently underway include support for using multiple concurrent Ansible versions to run jobs from its executor, and distributing the resource scheduler to eliminate it as a single point of failure.
