Unable to build qemu image using vyos-build docker container


I’m running into an issue trying to build the qemu image inside the vyos-build docker container. Starting with a Debian 9 VM, I had no issues building the docker container, then building the ISO using ‘make iso’. Trying to build the qemu image after that fails though, relevant output below:

I can provide the full list of commands used to get here, but they pretty much mirror the instructions in the github repo. I had the same results in a local VM and a cloud VM. I haven’t tried using a different docker host OS, but I can’t see why that should matter.

I’m also unable to build the GCE target, but that can get its own topic, since I don’t think its related to this error.

I’m up for contributing some documentation on building images using the vyos-build docker container if I can get this all working.


My in-progress documentation, which also serves as instructions to reproduce the above issue is here: https://wiki.vyos.net/wiki/Building_images_using_vyos-build_Docker_container


I figured this one out - the timing was a little too tight in the packer script, at least on my machine. I slowed a few of the steps down and got a successful build. Not sure if this is actually a bug, per se, since the performance is going to be machine dependant - but at least on the 4 machines I tried, the existing timing is too short.

Here’s the boot_command section of my edited packer.json:

"install image<enter><wait5>",
"set interface ethernet eth0 address dhcp<enter><wait20>",
"set service ssh<enter><wait5>",
"delete interface ethernet eth0 hw-id<enter><wait5>",

Some of the timing is probably a little slower than it needs to be, but I don’t think I waste more than a few minutes. I can submit a pull request with these changes if the devs are interested.


That worked for me. Thank you.
