Hi Lenny,


Even I am working on zuulv2 to v3 migration for IBM PowerKVM - https://wiki.openstack.org/wiki/ThirdPartySystems/IBMPowerKVMCIand so far we have setup a test VM wherein we have installed zuulv3 and Nodepool version: 3.7.2 and have migrated 4 of our jenkins jobs to ansible to work with zuulv3. Zuulv3 doesn't have much info online apart from the official documentation but I found the following blogs quite useful while doing the migration:
https://zuul-ci.org/docs/zuul/admin/quick-start.html- This is a very good installation tutorial to get a hang of zuulv3 that needs a single VM and it installs different components in docker containers. I started with this which helped me to understand how different components are configured.
Also, the following articles are good read.
1. https://www.softwarefactory-project.io/cicd-workflow-offered-by-zuulnodepool-on-software-factory.html
2. https://www.softwarefactory-project.io/zuul-hands-on-part-2-your-first-gated-patch-with-zuul.html
3. https://www.softwarefactory-project.io/zuul-hands-on-part-3-use-the-zuul-jobs-library.html

Openstack has migrated to zuulv3, so you can also check out their project configuration here - https://opendev.org/openstack/project-config

I am planning to write my experience of migration in a blog which I will let you know once complete. Let me know if you got any doubts while setting up zuulv3


Thanks and Regards,
