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
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).
We've talked about this for ages. ;) It was going to be part of a new
pkgdb, then standalone, then in a composedb thing. Not sure where it
is now. ;)
The scm admin script currently in use is pretty easy... it's usually
that we simply only have one scm admin at a time thats processing
There are further sequences down the pipeline like requesting
packages in testing be pushed to stable, but there are good
arguments against automating that.
To some extent thats already automated with the karma system. ;)
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.
yeah, but I think of that as more a dev thing than staging. Staging is
something you keep very close to production and only right before you
intend to go to production do you update staging.
Others might have differing thoughts on that...
I suspect that the "release only when we have accumulated
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).
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.
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
Yeah, something to ponder on for sure.
