When we export and import image data (for backup/restore purposes), we need to reset the ZK sequence counter for image builds in order to avoid collisions. The only way we can do that is to create and then delete a large number of znodes. Some sites (including OpenDev) have sequence numbers that are in the hundreds of thousands. To avoid this time-consuming operation (which is only intended to be run to restore from backup -- when operators are already under additional stress!), this change switches the build IDs from integer sequences to UUIDs. This avoids the problem with collisions after import (at least, to the degree that UUIDs avoid collisions). The actual change is fairly simple, but many unit tests need to be updated. Since the change is user-visible in the command output (image lists, etc), a release note is added. A related change which updates all of the textual references of build "number" to build "id" follows this one for clarity and ease of review. Change-Id: Ie7c68b094bc9733914a808756eeee8b62f696713
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.
