Multiple git repository relationship aware
Nodepool attaches single-use cloud slaves to Jenkins Master Pool
Triggers jobs on Jenkins Pool for executing job content

What is Zuul v3

Replace Jenkins with Ansible
Change zuul/nodepool interaction to zuul requesting N resources from nodepool +
- Zuul requests N resources from nodepool
- Zuul creates ansible inventory, passes to job executors
- Job executor runs job content on build resources using ansible + inventory
+
Add github PR integration in addition to gerrit
Add multi-tenancy for job configs and secrets
Add in-repo job configs - self testing CI config
Add reusable build resources (such as bare metal)
Add container build resources (docker, kubernetes)

+ +

Zuul v3 Current Status

Zuul v3 Spec is approved - OpenStack CI will move to it
First phase of all the hard bits is done in the v3 branch
Nodepool v2 branching now as nodepool/shade integration has landed
Estimate 2 months of effort to be at initial feature complete for OpenStack

Zuul v3 Future need

Supporting expanded userbases outside of OpenStack adds importance to original wishlist features +
- Github Integration
- Container Integration
- Non-OpenStack Cloud (AWS, GCE, Azure)
+
Github support for the v2 branch already written, not merged pending v3
Initial design for container integration done +
- Need a deeper detailed spec
+
Non-OpenStack Cloud simple to implement in nodepool v2

+ +

Zuul v2.5

Waiting for Zuul v3 got costly
Zuul "2.5" is a release-valve to solve immedate problems +
- Jenkins replaced by Ansible
- Ansible workers directly read Jenkins Job Builder templates
- Accelerating review of github PR patches with view of landing in weeks
