Hello, we will meet on November 9, 2021 at 19:00UTC in #opendev-meeting with this agenda (note the DST change in many parts of the world): == Agenda for next meeting == * Announcements * Actions from last meeting * Specs Review * Topics ** Improving OpenDev's CD throughput (clarkb 20211109) *** We can run many of our jobs in parallel in all of our CD pipelines. But this requires we properly document/address dependencies **** Need to understand our job dependencies and properly note them in Zuul config or address them by combining jobs. ***** Example 1: Combine service-gitea-lb and service-gitea jobs. ***** Example 2: Combine letsencrypt and nameserver jobs ***** Example 3: Have all jobs with webserver config express a dependency on the letsencrypt job **** Suggest we document the known job dependencies in a human readable format, then encode this into zuul, then we can switch to parallel runs. **** https://review.opendev.org/c/opendev/system-config/+/807672 ***** should list dependencies for all jobs ***** zuul doesn't trigger on this? not sure on best approach to make it mergable **** https://review.opendev.org/c/opendev/base-jobs/+/807807 ***** currently every executor adds keys for bridge, then logs in and clones system-config before running playbooks ***** this change makes split jobs to do this. however, production remains the same as both are called. **** https://review.opendev.org/c/opendev/system-config/+/807808 ***** this is a follow-on that adds a base job to clone system-config, and stops the other production jobs re-cloning. ***** this job must run first, but then all other jobs can run in parallel, as they are all in the same buildset and using the same "view" of system-config for that particular run ** Gerrit Account cleanups (clarkb 20211109) *** 33 conflicts remain. Clarkb has written notes on proposed plans for each user in the comments of review02:~clarkb/gerrit_user_cleanups/audit-results-annotated.yaml ** Zuul multi scheduler setup (clarkb 20211109) *** Zuul is currently running with two schedulers (zuul01.o.o and zuul02.o.o with zuul02.o.o being "primary") *** We have tracked down a number of bugs Monday with corvus fixing many of them. *** Overall seems stable enough. *** Note the "flapping" status page can be weird. ** User management on our systems (clarkb 20211109) *** Be explicit about uid/gid ranges: https://review.opendev.org/c/opendev/system-config/+/816869/ **** 0-999 system, 1000-1999 unallocated, 2000-2999 for infra-root users, 3000-9999 host level users, 10k - 64k container users that need uids on the host as well for bind mounts. *** Clean up unused bootstrapping users: https://review.opendev.org/c/opendev/system-config/+/816771 *** Give gerritbot and matrix-gerritbot a shared user: https://review.opendev.org/c/opendev/system-config/+/816769/ *** Eventually convert mariadb container's from uid 999 to something that makes more sense on the system. * Open discussion
