I think it's a great idea - it's related to ideas in this thread: https://lists.ceph.io/hyperkitty/list/dev@xxxxxxx/thread/UD43OL6YBN5A2QHLKRUQLYQRXMHM5FKJ/
The main idea there is to make it simple to update containers so you can run teuthology tests against code you just changed with very little overhead (no need to wait for hours for package + container complete rebuilds).
Zack Cerza has made a lot of progress on the teuthology side of this - running the tests locally using an existing container image. The 2nd half, of making it easy and fast to update a container image, is still TBD.

JohnI think your proposal to separate the build process such that the user can select an os flavor of their liking is a fantastic idea.I'm not familiar with the process to assist but would love to follow if this proposal is accepted._______________________________________________On Thu, Aug 11, 2022, 1:37 PM John Mulligan <phlogistonjohn@xxxxxxxxxxxxx> wrote:On the user's list one thread about the packages took a turn into discussing
building in containers [1]. This is a topic that I have had some idle
conversations about with Adam King and so I figured that I would raise this to
a wider audience.
My thought is to use container images specifically for building ceph - and not
just it's container images. The builds may continue to produce packages, but a
container would be used as an abstraction between the actual OS and the build
process of (do_cmake.sh, etc.).
Builder images would be be available for use both by the build system (jenkins
builders) as well as individual users. One advantage of this is that the user
can build the packages for distros that don't match the local distro. I've
also found it advantageous for my own builds to use the container to limit
memory and CPU for the build.
I'm curious if anyone has discussed this before. Does it interest anyone? I
am willing to volunteer some time to help as well.
Thanks for reading!
