Thanks for the release, especially after lxc-ci files were updated to work with incus!

Do I understand the code changes that distrobuilder is now incompatible with lxd? I.e., you can’t create lxd images anymore with it? Although I’d think the image format itself hasn’t changed much.

4

Right, all the commands were renamed from lxd over to incus though at this point the image format hasn’t diverged so you can just use the incus command and consume the image with LXD.

That’s effectively what anyone using LXD and consuming images from https://images.linuxcontainers.org (images remote) is doing today.

Just checked images.linuxcontainers and VyOS images are not there yet. Guessing it’s just the distrobuilder update for now. Will these images appear there as well?

6

While distrobuilder supports building VyOS images, nobody has yet contributed the config needed to have those builds happen on our infrastructure.

For anyone interested who knows enough about VyOS to get things up and running, we’d need a pull request at: GitHub - lxc/lxc-ci: LXC continuous integration and build scripts

7

Related to linux based router OS, do you know if IPFire is supported? I will eventually take a look at it and, if it is supported, I might spend some time to learn on how to configure it for distrobuilder. I might not do it for VyOS though.

8

I don’t know if they support running in containers, but if they do, then someone could add a source and package manager definition to the distrobuilder source so it would be possible to build those images.

9

Any plans to package and deliver Distrobuilder as non-snap?

10

You’d need to talk to packagers for your distro of choice.
As an upstream project, what we release are tarballs and git tags :slight_smile:

The snap was created back when we were all still at Canonical and as it hasn’t failed yet, we’ve just kept it on auto-pilot (it automatically builds itself).

For our own systems, we just use go install to download and build distrobuilder from source when needed.
