[edit]Team Business
[edit]- split the team/meetings up? (moved to end of meeting)
- The team overall likes being informed of all others activities.
- Peoplel can always set their own meetings to go deeper in details.
- Our team is slightly different than features, so one per week meeting is just fine.
- RelEng/QA things at the Hackathon
- https://phabricator.wikimedia.org/T92565
- Antoine has no clues / too many to pick :(
Escalation
[edit]- LocalizationUpdate issues:
- Chad / Mukunda will look at it
Team Quarterly Goals
[edit]https://phabricator.wikimedia.org/maniphest/query/O9isnUt5IGLP/#R
Scrum of Scrums
[edit]- https://phabricator.wikimedia.org/project/board/64/
- Blocked on us: https://phabricator.wikimedia.org/maniphest/?statuses=open%2Cstalled&allProjects=PHID-PROJ-arpazvuktn2l647rb6us#R
Beta Cluster stability
[edit]- https://phabricator.wikimedia.org/project/board/497/?order=priority
- Quarterly Priority: Green nightly builds on staging: https://phabricator.wikimedia.org/T88701
- Quarterly Priority: Stable uptime metrics of the Staging cluster: https://phabricator.wikimedia.org/T88705
- groundwork done mostly: ENC, Autosigner, autopuppetmaster, tin and palladium are functional
- Chad has ES patch (I think) Tyler has MX patch for operations puppet
- Next steps--think it's time to move on to apps
Test history
[edit]- Quarterly Priority: By team test history: https://phabricator.wikimedia.org/T88706
Slamed by MW-V things last week.
Isolated CI instances
[edit]- https://phabricator.wikimedia.org/tag/continuous-integration/board/?order=priority
- Quarterly Priority: Disposable VMs - https://phabricator.wikimedia.org/T47499
- Ops responds with a question: How many VMs, and what other hardware will this require?
- Roughly 10 at start, then ~ 50 which is the number of executors we have on current Jenkins. The pool size will depends on the speed to spawn a new instance and replenish the pool being consumed.
- The idea is to start with a few projects (ex: releng repos), then extend to the rest progressively starting end of June.
- 10 is not a problem, but for 50 we'll need to allocate new virt hardware.
- Some ops (_joe_, specifically) want to discuss using chroots instead. Andrew is struggling to get someone to respond to Antoine directly.
- We had exchanges last summer about isolation. chroots can be escaped, lxc/docker needs some additional isolation work. kvm is isolated out of the box and using openstack as a provider let us reuse the NodePool software already written. Though ideally we would use OpenStack + LXC to speed up the vm spawning.
- Ops responds with a question: How many VMs, and what other hardware will this require?
- Zuul package ready for precise and trusty
- need a review by an opsen (fillipo/godog)
- Antoine to contact fillipo
- Antoine to create procurment ticket
- This is the next big timesink/blocker
- Might need servers to be physically moved between racks.
- Antoine to loopback with Andrew B / Yuvi to present the arch and more or less validate it.
