Gitian building vagrant
Preparing the Gitian builder host
The first step is to prepare the host environment that will be used to perform the Gitian builds. This guide explains how to set up the environment, and how to start the builds.
- A machine with at least 64b of disk space
- 16GB of RAM
- Several installed tools:
After you have installed each of these tools, you will need to create an ubuntu xenial vagrant "box." This is most easily done using the box-cutter project. (Note: Canonical provides a vagrant box, however its disk space is insufficient for this guide.)
pushd cd /tmp/ git clone https://github.com/boxcutter/ubuntu.git cd ubuntu git checkout 7d1820c186d76122445c092bc2b872a8a94166ce packer build -var-file=ubuntu1604.json -only=virtualbox-iso ubuntu.json vagrant box add --name abc-xenial box/virtualbox/ubuntu1604-0.1.0.box popd
After completion you should be able to run add the box to vagrant as "abc-xenial"
vagrant box add --name abc-xenial <path_to_packer_output.box>
The final step for running vagrant is:
cd contrib/gitian/ vagrant up vagrant ssh
This should drop you into a Xenial prompt as the user
Setting up the Gitian image
Gitian needs a virtual image of the operating system to build in. Currently this is Debian Buster x86_64. This image will be copied and used every time that a build is started to make sure that the build is deterministic. Creating the image will take a while, but only has to be done once.
Execute the following as user
cd gitian-builder ./bin/make-base-vm --lxc --distro debian --suite buster --arch amd64
There will be a lot of warnings printed during the build of the image. These can be ignored.
