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).

.. note:: 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

.. code-block:: sh

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

.. code-block:: sh

  root@build:~$ usermod -aG docker user

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


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

.. code-block:: sh

  user@build:~$ git clone -b crux --single-branch https://github.com/vyos/vyos-build.git
  user@build:~$ cd vyos-build
  user@build:~/vyos-build$ docker build -t vyos-builder docker
  
  
Running the container and building the ISO 


.. code-block:: sh

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