@soltysh On what SIG can I discuss this feature? I want to have a longer discussion about third-party resources for this feature and why we feel it needs to be built into core.

Let's use SIG-Apps for now. There has not been a lot of discussion of controllers there, that I have seen, but lets try and see how it goes.

Is this being considered for exclusion from the core? I had thought the proposal was already accepted.

My understanding was that this was accepted into core, while job workflow was rejected for core. In fact we had originally planned to have it in 1.3.

@soltysh I interpreted the comment as implying that it would be in core (based on the mention of alpha/beta and the statement "If someone were to produce a third-party version of scheduledJob, well before 1.4, and show that was comparably useful, that would be persuasive argument for the latter path" where the latter path was ThirdParty).

@davidopp that comment was made when I thought SJ would be Beta in 1.4. Now it is going to Alpha in 1.4. The philosophy was that we can cancel an alpha feature for whatever reason, but we should have a pretty high bar for cancelling a beta feature.

Also, to all working on SJ: we should continue work at full speed, despite the above conversation. Much of the work will apply either way, and we need to get some kind of feature out to users so they can give feedback.

All SJ work is at full speed, the only remaining problem (hopefully) is to have kubernetes/kubernetes#29187 in. I'm hoping to discuss this issue with @smarterclayton today or over the weekend and have it merged so next week we should see one after the other SJ PRs being merged.

@janetkuo I usually mark them done once they merge. With that in mind I've checked the one against branch 1.4, the other will wait for merge.

This feature is still attached to milestone 1.4, and the 1.6 milestone spreadsheet doesn't mention anything about Cron/ScheduledJobs.

Is this still on-schedule for a 1.6 beta release? As a GKE customer, I would love to start moving all our out-of-cluster crons onto the cluster itself (without using cronetes).

Indeed. This a much needed feature has been dragging on from 1.3 version if I am not mistaken. Myself I am in the same position - can not wait till it comes across so I can start pulling the on premise jobs onto GKE.

I've modified the milestone to next, there are still quite a lot of work to be done for CronJobs to stabilize them, I'd love to push it forward more aggressive, but unfortunately the lack of time is the main factor I can't atm.

@idvoretskyi partially, the promotion to beta was targeted for 1.8 and happened in that timeframe. There's no milestone set for this, b/c there's no clear plan for the future promotion to stable, yet.

For the 1.10 milestone there are 3 topics:

  1. TimeZone support in CronJob (kubernetes/kubernetes#47266) - @iterion see this comment for reasoning why
  2. CronJob manual instantiation (kubernetes/kubernetes#53988) - @erhudy
  3. (?) Re-write the controller to use shared informers (kubernetes/kubernetes#17130) - @soltysh

Controller re-write to satisfy kubernetes/kubernetes#17130 but I'm still struggling with time. So this is more of a wishful thinking than actual plans 😉
