- -
- -Note - -
- -Starting with VyOS 1.2 the release model of VyOS has changed. VyOS -is now **free as in speech, but not as in beer**. This means that while -VyOS is still an open source project, the release ISOs are no longer free -and can only be obtained via subscription, or by contributing to the -community. - -The source code remains public and an ISO can be built using the process -outlined in this chapter. - -
- -### Native Build - -To build VyOS natively you require a properly configured build host with the -following Debian versions installed: - -- Debian Jessie for VyOS 1.2 (crux) -- Debian Buster for VyOS 1.3 (equuleus) -- Debian Bookworm for VyOS 1.4 (sagitta) -- Debian Bookworm or updated for VyOS 1.5 (circinus, current) - aka the - rolling release - -To start, clone the repository to your local machine: - -``` none -# For VyOS 1.2 (crux) -$ git clone -b crux --single-branch https://github.com/vyos/vyos-build - -# For VyOS 1.3 (equuleus) -$ git clone -b equuleus --single-branch https://github.com/vyos/vyos-build - -# For VyOS 1.4 (sagitta) -$ git clone -b sagitta --single-branch https://github.com/vyos/vyos-build - -# For VyOS 1.5 (circinus, current) -$ git clone -b current --single-branch https://github.com/vyos/vyos-build - -$ cd vyos-build - -# For VyOS 1.2 (crux) and VyOS 1.3 (equuleus) -$ ./configure --architecture amd64 --build-by "j.randomhacker@vyos.io" -$ sudo make iso - -# For VyOS 1.4 (sagitta) and VyOS 1.5 (circinus, current) -$ sudo make clean -$ sudo ./build-vyos-image iso --architecture amd64 --build-by "j.randomhacker@vyos.io" -``` - -For the packages required, you can refer to the `docker/Dockerfile` file -in the [repository](https://github.com/vyos/vyos-build). The `./build-vyos-image` script will also warn you if any -dependencies are missing. - -### Docker - -This will guide you through the process of building a VyOS ISO using [Docker](https://www.docker.com). -This process has been tested on clean installs of Debian Bullseye (11) and -Bookworm (12). - -Installing [Docker](https://www.docker.com) and prerequisites: - -
- -
- -Hint - -
- -Due to the updated version of Docker, the following examples may -become invalid. - -Due to differences in version updates and build processes, content related -to VyOS 1.3 and below is no longer included below. - -
- -[On Debian](https://docs.docker.com/engine/install/debian/) - -``` none -# Add Docker's official GPG key: -$ sudo apt-get update -$ sudo apt-get install ca-certificates curl gnupg -$ sudo install -m 0755 -d /etc/apt/keyrings -$ curl -fsSL https://download.docker.com/linux/debian/gpg | sudo gpg --dearmor -o /etc/apt/keyrings/docker.gpg -$ sudo chmod a+r /etc/apt/keyrings/docker.gpg - -# Add the repository to Apt sources: -$ echo \ - "deb [arch=$(dpkg --print-architecture) signed-by=/etc/apt/keyrings/docker.gpg] \ - https://download.docker.com/linux/debian \ - $(. /etc/os-release && echo "$VERSION_CODENAME") stable" | \ - sudo tee /etc/apt/sources.list.d/docker.list > /dev/null - -$ sudo apt-get update -$ sudo apt-get install docker-ce docker-ce-cli containerd.io docker-buildx-plugin docker-compose-plugin -``` - -To be able to use [Docker](https://www.docker.com) without `sudo`, the current non-root user must be -added to the `docker` group by calling: `sudo usermod -aG docker yourusername`. - -
- -
- -Hint - -
- -Doing so grants privileges equivalent to the `root` user! It is -recommended to remove the non-root user from the `docker` group after -building the VyOS ISO. See also [Docker as non-root](https://docs.docker.com/engine/install/linux-postinstall). - -
- -
- -
- -Note - -
- -The build process needs to be built on a local file system, building -on SMB or NFS shares will result in the container failing to build properly! -VirtualBox Drive Share is also not an option as block device operations -are not implemented and the drive is always mounted as "nodev" - -
- -#### Build Container - -The container can be built by hand or by fetching the pre-built one from -DockerHub. Using the pre-built containers from the [VyOS DockerHub -organisation](https://hub.docker.com/u/vyos) will ensure that the container is always up-to-date. A rebuild -is triggered once the container changes (please note this will take 2-3 hours -after pushing to the vyos-build repository). - -##### Dockerhub - -To manually download the container from DockerHub, run: - -``` none -$ docker pull vyos/vyos-build:sagitta # For VyOS 1.4 -$ docker pull vyos/vyos-build:current # For rolling release -``` - -##### Build from source - -The container can also be built directly from source: - -``` none -# For VyOS 1.4 (sagitta) -$ git clone -b sagitta --single-branch https://github.com/vyos/vyos-build - -# For VyOS 1.5 (circinus, current) -$ git clone -b current --single-branch https://github.com/vyos/vyos-build - - -$ cd vyos-build -$ docker build -t vyos/vyos-build:sagitta docker # For VyOS 1.4 -$ docker build -t vyos/vyos-build:current docker # For rolling release -``` - -
- -
- -Note - -
- -Since VyOS has switched to Debian (12) Bookworm in its `current` -branch, It is recommended to use the official Docker Hub container image -to build `equleus` and `crux`. - -
- -#### Tips and Tricks - -You can create yourself some handy Bash aliases to always launch the latest - -per release train (current or sagitta) - container. Add the following to -your `.bash_aliases` file: - -``` none -alias vybld='docker pull vyos/vyos-build:current && docker run --rm -it \ - -v "$(pwd)":/vyos \ - -v "$HOME/.gitconfig":/etc/gitconfig \ - -v "$HOME/.bash_aliases":/home/vyos_bld/.bash_aliases \ - -v "$HOME/.bashrc":/home/vyos_bld/.bashrc \ - -w /vyos --privileged --sysctl net.ipv6.conf.lo.disable_ipv6=0 \ - -e GOSU_UID=$(id -u) -e GOSU_GID=$(id -g) \ - vyos/vyos-build:current bash' - -alias vybld_sagitta='docker pull vyos/vyos-build:sagitta && docker run --rm -it \ - -v "$(pwd)":/vyos \ - -v "$HOME/.gitconfig":/etc/gitconfig \ - -v "$HOME/.bash_aliases":/home/vyos_bld/.bash_aliases \ - -v "$HOME/.bashrc":/home/vyos_bld/.bashrc \ - -w /vyos --privileged --sysctl net.ipv6.conf.lo.disable_ipv6=0 \ - -e GOSU_UID=$(id -u) -e GOSU_GID=$(id -g) \ - vyos/vyos-build:sagitta bash' -``` - -Now you are prepared with two new aliases `vybld` and `vybld_sagitta` to -spawn your development containers in your current working directory. - -
- -
- -Note - -
- -Some VyOS packages (namely vyos-1x) come with build-time tests which -verify some of the internal library calls that they work as expected. Those -tests are carried out through the Python Unittest module. If you want to -build the `vyos-1x` package (which is our main development package) you -need to start your Docker container using the following argument: -`--sysctl net.ipv6.conf.lo.disable_ipv6=0`, otherwise those tests will -fail. - -
- -## Build ISO - -Now as you are aware of the prerequisites we can continue and build our own -ISO from source. For this we have to fetch the latest source code from GitHub. -Please note as this will differ for both current and crux. - -``` none -# For VyOS 1.4 (sagitta) -$ git clone -b sagitta --single-branch https://github.com/vyos/vyos-build - -# For VyOS 1.5 (circinus, current) -$ git clone -b current --single-branch https://github.com/vyos/vyos-build -``` - -Now a fresh build of the VyOS ISO can begin. Change directory to the -`vyos-build` directory and run: - -``` none -$ cd vyos-build - -# For VyOS 1.4 (sagitta) -$ docker run --rm -it --privileged -v $(pwd):/vyos -w /vyos vyos/vyos-build:sagitta bash - -# For VyOS 1.5 (circinus, current) -$ docker run --rm -it --privileged -v $(pwd):/vyos -w /vyos vyos/vyos-build:current bash -``` - -``` none -# For MacOS (crux, equuleus, sagitta) -$ git clone https://github.com/vyos/vyos-utils-misc -$ cd build-tools/macos-build - -# For VyOS 1.2 (crux) -$ os=jessie64 branch=crux make build - -# For VyOS 1.3 (equuleus) -$ os=buster64 branch=equuleus make build - -# For VyOS 1.4 (sagitta) -$ os=buster64 branch=sagitta make build -``` - -Start the build: - -``` none -# For VyOS 1.4 (sagitta) and For VyOS 1.5 (circinus, current) -vyos_bld@8153428c7e1f:/vyos$ sudo make clean -vyos_bld@8153428c7e1f:/vyos$ sudo ./build-vyos-image iso --architecture amd64 --build-by "j.randomhacker@vyos.io" -``` - -When the build is successful, the resulting iso can be found inside the -`build` directory as `live-image-[architecture].hybrid.iso`. - -Good luck! - -
- -
- -Hint - -
- -Building VyOS on Windows WSL2 with Docker integrated into WSL2 will -work like a charm. No problems are known so far! - -

The -file `data/defaults.toml` hosts a TOML definition of the kernel version used -`kernel_version` and the `kernel_flavor` of the kernel which represents the -kernel's LOCAL_VERSION. Both together form the kernel version variable in the -system: - -``` none -vyos@vyos:~$ uname -r -6.1.52-amd64-vyos -``` - -- Accel-PPP -- Intel NIC drivers -- Inter QAT - -Each of those modules holds a dependency on the kernel version and if you are -lucky enough to receive an ISO build error which sounds like: - -``` none -I: Create initramfs if it does not exist. -Extra argument '6.1.52-amd64-vyos' -Usage: update-initramfs {-c|-d|-u} [-k version] [-v] [-b directory] -Options: - -k version Specify kernel version or 'all' - -c Create a new initramfs - -u Update an existing initramfs - -d Remove an existing initramfs - -b directory Set alternate boot directory - -v Be verbose -See update-initramfs(8) for further details. -E: config/hooks/live/17-gen_initramfs.chroot failed (exit non-zero). You should check for errors. -``` - -The most obvious reasons could be: - -- `vyos-build` repo is outdated, please `git pull` to update to the latest - release kernel version from us. -- You have your own custom kernel \*.deb packages in the packages folder but - neglected to create all required out-of tree modules like Accel-PPP, Intel - QAT or Intel NIC drivers - -#### Building The Kernel - -The kernel build is quite easy, most of the required steps can be found in the -`vyos-build/packages/linux-kernel/Jenkinsfile` but we will walk you through -it. - -Clone the kernel source to \`vyos-build/packages/linux-kernel/\`: - -``` none -$ cd vyos-build/packages/linux-kernel/ -$ git clone https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git -``` - -Check out the required kernel version - see `vyos-build/data/defaults.toml` -file (example uses kernel 4.19.146): - -``` none -$ cd vyos-build/packages/linux-kernel/linux -$ git checkout v4.19.146 -Checking out files: 100% (61536/61536), done. -Note: checking out 'v4.19.146'. - -You are in 'detached HEAD' state. You can look around, make experimental -changes and commit them, and you can discard any commits you make in this -state without impacting any branches by performing another checkout. - -If you want to create a new branch to retain commits you create, you may -do so (now or later) by using -b with the checkout command again. Example: - - git checkout -b - -HEAD is now at 015e94d0e37b Linux 4.19.146 -``` - -Now we can use the helper script `build-kernel.sh` which does all the -necessary voodoo by applying required patches from the -vyos-build/packages/linux-kernel/patches folder, copying our kernel -configuration `x86_64_vyos_defconfig` to the right location, and finally -building the Debian packages. - -
- -
- -Note - -
- -Building the kernel will take some time depending on the speed and -quantity of your CPU/cores and disk speed. Expect 20 minutes -(or even longer) on lower end hardware. - -

The rules we have are not there to punish you - the -rules are in place to help us all. What does it mean?

This seems to be a bit odd -nowadays but as some people also work remotely or program using vi(m) this is -a fair good standard which I hope we can rely on. - -In addition this also helps when browsing the GitHub codebase on a mobile -device if you happen to be a crazy scientist. - -``` python -#!/usr/bin/env python3 -# -# Copyright (C) 2020 VyOS maintainers and contributors -# -# This program is free software; you can redistribute it and/or modify -# it under the terms of the GNU General Public License version 2 or later as -# published by the Free Software Foundation. -# -# This program is distributed in the hope that it will be useful, -# but WITHOUT ANY WARRANTY; without even the implied warranty of -# MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.

No other function is allowed to call the `vyos.config. Config` object method directly. The rationale for it is that when config reads -are mixed with other logic, it's very hard to change the config syntax since -you need to weed out every occurrence of the old syntax.

It should use non-disruptive reload whenever possible. It may execute -disruptive operations such as daemon process restart if a particular component -does not support non-disruptive reload, or when the expected service degradation -is minimal (for example, in case of auxiliary services such as LLDPd). In case -of high impact services such as VPN daemon and routing protocols, when non- -disruptive reload is supported for some but not all types of configuration -changes, scripts authors should make effort to determine if a configuration -change can be done in a non-disruptive way and only resort to disruptive restart -if it cannot be avoided. - -Unless absolutely necessary, configuration scripts should not modify the active -configuration of system components directly. Whenever at all possible, scripts -should generate a configuration file or files that can be applied with a single -command such as reloading a service through systemd init. Inserting statements -one by one is particularly discouraged, for example, when configuring netfilter -rules, saving them to a file and loading it with iptables-restore should always -be preferred to executing iptables directly. - -The `apply()` and `generate()` functions may `raise ConfigError` if, for -example, the daemon failed to start with the updated config. It shouldn't be a -substitute for proper config checking in the `verify()` function. All -reasonable effort should be made to verify that generated configuration is -valid and will be accepted by the daemon, including, when necessary, cross- -checks with other VyOS configuration subtrees. - -Exceptions, including `VyOSError` (which is raised by `vyos.config.Config` -on improper config operations, such as trying to use `list_nodes()` on a -non-tag node) should not be silenced or caught and re-raised as config error. -Sure this will not look pretty on user's screen, but it will make way better -bug reports, and help users (and most VyOS users are IT professionals) do their -own debugging as well. - -For easy orientation we suggest you take a look on the `ntp.py` or -`interfaces-bonding.py` (for tag nodes) implementation. Both files can be -found in the [vyos-1x](https://github.com/vyos/vyos-1x/tree/current/schema) repository. - -## XML (used for CLI definitions) - -The bash (or better vbash) completion in VyOS is defined in *templates*. -Templates are text files (called `node.def`) stored in a directory tree. The -directory names define the command names, and template files define the command -behaviour. Before VyOS 1.2 (crux) this files were created by hand. After a -complex redesign [process](https://blog.vyos.io/vyos-development-digest-10) the new style template are automatically generated -from a XML input file. - -XML interface definitions for VyOS come with a RelaxNG schema and are located -in the [vyos-1x](https://github.com/vyos/vyos-1x/tree/current/schema) module. This schema is a slightly modified schema from [VyConf](https://github.com/vyos/vyconf/tree/master/data/schemata) -alias VyOS 2.0 So VyOS 1.2.x interface definitions will be reusable in Nextgen -VyOS Versions with very minimal changes. - -The great thing about schemas is not only that people can know the complete -grammar for certain, but also that it can be automatically verified. The -scripts/build-command-templates script that converts the XML definitions to -old style templates also verifies them against the schema, so a bad definition -will cause the package build to fail. I do agree that the format is verbose, but -there is no other format now that would allow this. Besides, a specialized XML -editor can alleviate the issue with verbosity. - -Example: - -``` xml - - - - - - - - Task scheduler settings - - - - - Scheduled task - - <string> - Task name - - 999 - - - - - UNIX crontab time specification string - - - - - Execution interval - - <minutes> - Execution interval in minutes - - - <minutes>m - Execution interval in minutes - - - <hours>h - Execution interval in hours - - - <days>d - Execution interval in days - - - [1-9]([0-9]*)([mhd]{0,1}) - - - - - - Executable path and arguments - - - - - Path to executable - - - - - Arguments passed to the executable - - - - - - - - - - - -``` - -Command definitions are purely declarative, and cannot contain any logic. All -logic for generating config files for target applications, restarting services -and so on is implemented in configuration scripts instead. - -### GNU Preprocessor - -XML interface definition files use the xml.in file extension which was -implemented in `T1843`. XML interface definitions tend to have a lot of -duplicated code in areas such as: - -- VIF (incl. VIF-S/VIF-C) -- Address -- Description -- Enabled/Disabled - -Instead of supplying all those XML nodes multiple times there are now include -files with predefined features.
