Installation

Requirements

The recommended system requirements are 512 MiB RAM and 2 GiB storage.

Getting the software

Registered subscribers can download stable release (LTS) images. If you log into https://support.vyos.io/ as a registered subscriber, you will see the “Downloads” link there.

Non-subscribers can get the LTS release by building it from source. Just follow the instructions in https://github.com/vyos/vyos-build

Everyone can dowload VyOS rolling images from https://downloads.vyos.io/

Preparing software verification

This subsection and the following one applies to dowloaded LTS images, for other cases please jump to Install.

LTS images are signed by VyOS lead package-maintainer private key. If you have our public key, you will be able to verify the authenticity of the package.

First you need to install GPG or another OpenPGP implementation. On most GNU+Linux distributions it is installed by default because package managers use it to verify package signatures. On other systems you may need to find and install the package.

Then you need VyOS public key. If you already have it, you can jump to GPG verification. If you don’t have it yet, you can get it from a key server.

gpg --recv-keys FD220285A0FE6D7E

Or open your web browser, visit a key server and copy our public key from there: https://pgp.mit.edu/pks/lookup?op=get&search=0xFD220285A0FE6D7E

Or from this block below.

Then you can paste that text in a new file, and import the file into GPG:

gpg --import file_with_the_public_key

You can now check your GPG software has our public key.

$ gpg --list-keys
...
pub   rsa4096 2015-08-12 [SC]
    0694A9230F5139BF834BA458FD220285A0FE6D7E
uid           [ unknown] VyOS Maintainers (VyOS Release) <maintainers@vyos.net>
sub   rsa4096 2015-08-12 [E]

GPG verification

As you have our public key, you just need the signature of the software you want to verify.

Note

In order to get the signature, go to your web browser and append .asc to the URL of your dowloaded VyOS image. You will download a small .asc file, that’s the signature of your image.

So finally you can verify the authenticity of your image.

$ gpg2 --verify vyos-1.2.1-amd64.iso.asc  vyos-1.2.1-amd64.iso
gpg: Signature made So 14 Apr 12:58:07 2019 CEST
gpg:                using RSA key FD220285A0FE6D7E

Install

The VyOS ISO is a Live CD and will boot to a functional VyOS image. To login to the system, use the default username vyos with password vyos.

The programs included with the Debian GNU/Linux system are free software;
the exact distribution terms for each program are described in the
individual files in /usr/share/doc/*/copyright.

Debian GNU/Linux comes with ABSOLUTELY NO WARRANTY, to the extent
permitted by applicable law.
vyos@vyos:~$

vyos@vyos:~$ uname -a
Linux vyos 4.18.11-amd64-vyos #23 SMP Mon Oct 1 17:29:22 CEST 2018 x86_64 GNU/Linux

Unlike general purpose Linux distributions, VyOS uses “image installation” that mimics the user experience of traditional hardware routers and allows you to keep multiple VyOS versions on the same machine and switch to a previous version if something breaks after upgrade. Every version is contained in its own squashfs image that is mounted in a union filesystem together with a directory for mutable data (configs etc.).

Note

Older versions used to support non-image installation (install system command). Support for this is removed from VyOS 1.2 (crux) and newer releases

This installation method has been deprecated since the time image installation was introduced (long before the fork), and does not provide any version management capabilities. You should not use it for new installations even if it’s still available in new versions. You should not worry about older systems installed that way though, they can be upgraded with add system image.

To install VyOS, run install image.

vyos@vyos:~$ install image
Welcome to the VyOS install program.  This script
