This is just a shorter version of this blog entry, but building on equuleus instead of crux.

podman pull vyos/vyos-build:equuleus
git clone -b equuleus --single-branch https://github.com/vyos/vyos-build
cd vyos-build
sudo podman run --rm -it --privileged -v $(pwd):/vyos -w /vyos vyos/vyos-build:equuleus bash

./configure --architecture amd64 --build-by "me@example.com" --build-type release --version 1.3.2 --custom-package "mosh ripgrep"

sudo make iso

ls -lah build/vyos-1.3.2-amd64.iso
-rw-r--r-- 1 root root 321M Sep 10 02:06 build/vyos-1.3.2-amd64.iso

I'm not sure why the container needs to be run as privileged, but I have been too lazy to test what happens if it's not. :-) The build took approx. 10 minutes on my fairly old Skylake CPU.

It might be worth noting that the version number specified in the configuration above is nothing magical – it's just telling the build script what it should be called. I built in the latest commit which today just happened to be the right commit (7ce865118886358efde71a5d3782d21063b01a22) for 1.3.2. If I'd been more picky I'd checked out the right tag for this branch, which can be found here: https://github.com/vyos/vyos-build/tags

Install it, I first copied (scp) my iso to /tmp/vyos-1.3.2-amd64.iso:

$ add system image /tmp/vyos-1.3.2-amd64.iso
Checking SHA256 checksums of files on the ISO image... OK.
Done!
What would you like to name this image? [1.3.2]:
OK.  This image will be named: 1.3.2
Installing "1.3.2" image.
