This is intended to simplify efficient driver implementation by isolating ZooKeeper and other internal Nodepool logic from cloud implementation, while at the same time reducing the need for threads. It is based on the simple driver interface, but by using state machines, it can accomodate clouds (like Azure and OpenStack) which require multiple steps to create an instance. It's currently only suitable for use with a single pool, because the launcher's poolworkers are multiple threads. However, we should be able to collapse them into one thread which would make this safe for use with multiple pools. We may also need to adjust some of the sleep times in the launcher to accomodate the idea that the pool worker threads will be more active in driving the state machine polling.

Nodepool
Nodepool is a system for managing test node resources. It supports launching single-use test nodes from cloud providers as well as managing access to pre-defined pre-existing nodes. Nodepool is part of a suite of tools that form a comprehensive test system, including Zuul.
The latest documentation for Nodepool is published at: https://zuul-ci.org/docs/nodepool/
The latest documentation for Zuul is published at: https://zuul-ci.org/docs/zuul/
Getting Help
There are two Zuul-related mailing lists:
- zuul-announce
-
A low-traffic announcement-only list to which every Zuul operator or power-user should subscribe.
- zuul-discuss
-
General discussion about Zuul, including questions about how to use it, and future development.
You will also find Zuul developers in the #zuul channel on Freenode IRC.
