Things like fedora-review and fedora-create-review (and bodhi!) are a huge help. But there are plenty of inefficient "blocking" points in the process. For instance, once a new package is approved, only then does the submitter declare what branches they want with an scm admin request. They then wait for an scm admin to declare that they have created their branches, and then wait for a cronjob to run that gives them permission to push on those branches (manually). They then wait for their koji builds to finish to (manually) submit bodhi updates. It would be nice if we could automate that whole process -- once a package is approved, if there were a "make-it-so" button that required no further intervention from the packager (but still required the keen eye of an scm admin). There are further sequences down the pipeline like requesting that packages in testing be pushed to stable, but there are good arguments against automating that. 2) Continuous deployment for infrastructure. It has been tossed around in IRC, possibly at FUDCon as well. If application developers could "git push" on the develop branch and have those changes automatically roll out to our staging infrastructure -- that would save a lot of time. Packaging our apps, building rpms, signing them, copying them to our infra yum repos, rebuilding those repos, clearing the cache on the target machines, performing a yum update <-- that process is cumbersome. I suspect that the "release only when we have accumulated enough changes to warrant enduring the burdensome release process" mode of deployment (as opposed to "release early, release often") also poses somewhat of a barrier to new contributors. They contribute a patch.. nice! When does it go live? When one of our overstretched sysadmin-mains can get around to it (it is required that one of them sign the package). Caveat #2.1: There are some ways around this. Individuals can get around the requirement of having a sysadmin-main touch their test release by installing their rpm directly on the target machine. They still have to jump through some hoops to make it happen. Caveat #2.2: This is one of the reasons we put so much work into our private cloud (dev nodes). There is no barrier there for teams to set up their own continuous deployment mechanism. This meets most needs, but we don't have a way to iterate rapidly on some of the more important pieces of our infrastructure. Apps/services that interact with each other don't quite work out on isolated cloud nodes. The bodhi masher? Koji? fedmsg? mirror manager? We can't necessarily test those on dev nodes (and some we can't test in staging -- resolving this down the road would save some headaches).

----- Original Message ----- This would be super. And yes - I think that the "instant gratification" combined with having to know what is likely a lot less process seems like it would yield additional contributions. Do we have tiers for apps according to their "must stay-up" level - things that are critical vs. NTH? It seems like something where we could probably pick a non-critical app or two and work out what the process would be and basically take that process for a in-production-test-run. So I'm definitely treading into "woefully technically unedumacated" territory - but could we not just take snapshots of the associated apps/services/databases, test whatever changes are incoming against the snapshots, and if it passes, push the changes to production and dump the tested nodes? (I realize this is simplifying things - we might have changes that require changes in both places, etc - but just wondering if I'm totally off-base here.) Or is this just a matter of "the infra things aren't running in the same place"? -robyn

Off the top of my head: - I would LOVE to have the nightly-compose stuff automated. I just never get time to work on it. Ideally it would just be part of rawhide or branched compose scripts, run the builds, generate a nice web page that has FAILED or OK or whatever on it, as well as sending a report to the devel/test lists with things like packages added, packages removed, size change, etc. - For that matter I know Dennis has wanted a compose app for a long time that would be better than our current cron jobs to compose branched/rawhide/testcomposes/release candidates. Such an app could continue to provide email reports, but could also have a dashboard so you could see what was what and view logs easily, etc. - Longer term/down the road, it would be nice if koji had cloud awareness. Instead of having a static pool of builders preallocated, if it could just talk to a openstack cloud or something and ask for a instance, wait for it, use it, terminate it. Kevin
