Building VyOS using Docker

This will guide you though the process of building a VyOS ISO yourself using Docker and works best on a fresh installation of Debain 9 (Stretch).


Starting with VyOS 1.2 the developers have decided to change their release model. VyOS is now free as in speech, but not as in beer, meaning that while VyOS is still an open source project, the release ISO’s are no longer free and can only be obtained via subscription, or by contributing to the community. Since the source code is still public you can build your own ISO using the process described here.

Installing Docker and it’s prequisites

root@build:~$ apt update
root@build:~$ apt install apt-transport-https ca-certificates curl gnupg2 software-properties-common
root@build:~$ curl -fsSL | sudo apt-key add -
root@build:~$ add-apt-repository "deb [arch=amd64] $(lsb_release -cs) stable"
root@build:~$ apt update
root@build:~$ apt install docker-ce

Adding you user to the docker group to be able to execute the docker command without sudo

root@build:~$ usermod -aG docker user


It is recommended to use a non-root user from here on out

Cloning the vyos-build crux branch and creating the docker container

user@build:~$ git clone -b crux --single-branch
user@build:~$ cd vyos-build
user@build:~/vyos-build$ docker build -t vyos-builder docker

Running the container and building the ISO

user@build:~$ docker run --rm -it --privileged -v $(pwd):/vyos -w /vyos vyos-builder bash
vyos_bld@d4220bb519a0:/vyos# ./configure --architecture amd64 --build-by "your@email.tld" --build-type release --version 1.2.0
vyos_bld@d4220bb519a0:/vyos# sudo make iso

You may use these options to customize you ISO

-h, --help            show this help message and exit
--architecture ARCHITECTURE
                      Image target architecture (amd64 or i586 or armhf)
--build-by BUILD_BY   Builder identifier (e.g.
--custom-package CUSTOM_PACKAGES
                      Custom packages to install from repositories
--build-type BUILD_TYPE
                      Build type, release or development
--debian-security-mirror DEBIAN_SECURITY_MIRROR
                      Debian security updated mirror
--version VERSION     Version number (release builds only)
--debian-mirror DEBIAN_MIRROR
                      Debian repository mirror for ISO build
--vyos-mirror VYOS_MIRROR
                      VyOS package mirror
--pbuilder-debian-mirror PBUILDER_DEBIAN_MIRROR
                      Debian repository mirror for pbuilder env bootstrap
--debug               Enable debug output
--custom-apt-entry CUSTOM_APT_ENTRY
                      Custom APT entry

Your freshly built ISO should now be in the build directory. Good luck!
