925912 - Create Docker images or chroot tarballs from puppetagain systems

Status: RESOLVED WONTFIX

(Infrastructure & Operations :: RelOps: Puppet, task)

Description

[Dustin J. Mitchell [:dustin] (he/him)]

Right now, if a dev wants access to a system that's functionally identical to a releng system, there are two options: set up a whole PuppetAgain environment and build one, or borrow one from releng.  The first is really time-consuming, so nobody's ever done it (that I know of).  The second is pretty easy.  But what if we had an in-between option?

There are lots of tools out there that allow you to run lightweight virtual environments on linux: good old "chroot" and Docker come to mind.

Could we release either a chroot tarball, built from a freshly-imaged, stripped linux build host, periodically?  Similarly, could we do that with Docker, so devs can really easily spin up an LXC containing a build system from a certain date?

Dupe of bug 896023?

Why did nobody copy me on that :(

Comment 3

Ah, now that I carefully read the first comment, that's about archiving the mock environments, not the whole system.  So, different (and probably more useful to you).

Comment 4

My contention in bug 896023 is that because we are using chroots for the build environment, the "outer" operating system is all but irrelevant. It's only important for RelEng AFAICT.

We talk about this as an idea every few months.  However, it's not required yet, so no reason to work on it.  Re-open if/when it's required.
