EasyGitian provides a means of building a Virtual Machine in Virtualbox (more coming) capable of building coin projects with LXC containers as described in bitcoincore's gitian-building and release-process documents.
EasyGitian provides scripts for OSX & Linux to operate Vagrant & Virtualbox, (VPS providers coming soon) and a Vagrantfile to get your build system up and running quickly
EasyGitian is usuable on Windows, but requires the builder to use vagrant to operate the Virtual Machine directly, rather than having most operations scripted (batch/powershell scripts welcome!)

EasyGitian will attempt to install what is needed to build a VM and install gitian The build environment is configured, and you'll be asked
You should be able to build most coins that provide a contrib/gitian-descriptors directory in the same fashion as Bitcoin, BitcoinCash, Maza.
EasyGitian will attempt to read the gitian-descriptors files to determine what build system and architecture you need in your build environment to build your chosen coin. (please post errors in the github issues in this repo)
Look in the repo library for your chosen coin for {coin}-detached-sigs and gitian.sigs repositories (i.e. https://github.com/mazacoin/gitian.sigs https://github.com/pivx-project/pivx-detached-sigs) These are needed to assert and/or verify your build. When EasyGitian configures your build, it will ask for these URLs and ask if you'd like to Verify the builds.
When EasyGitian verifies the build, it will ensure you have the keys found in (i.e. https://github.com/mazacoin/maza/contrib/gitian-keys) and compare the hashes from your build to those found in the gitian.sigs repo, and show you any mismatches.
Future versions will fully support developer's assertions and commit assertions to the gitian.sigs repo

If these are on the same volume, 50GB is sufficientIf you need assistance installing GPG and Xcode tools and getting this repo cloned via git, an installer is provided:
(Open a Terminal)
curl -O https://raw.githubusercontent.com/mazaclub/easygitianbuilder/v0.1.0/Install_EasyGitian.sh
cat Install_EasyGitian.sh
chmod +x Install_EasyGitian.sh
./Install_EasyGitian.shYou'll be given a choice to install GPG from GPGTools.org or via Homebrew, and install either Xcode or the required Developer Command Line tools. This repo will be cloned, and EasyGitian will be started for you.
If your system already has this, you can simply clone the repo, and get started:
git clone https://github.com/mazaclub/EasyGitianBuilder easygitianbuilder
cd ./easygitianbuilder
./EasyGitianVagrant & Virtualbox will be downloaded, verified, and installed A Vagrant "base box" (debian-contribjessie) will be downloaded EasyGitian will build a Vagrant/Virtualbox VM and setup a build environment A build will begin.
To run another build, simply open a terminal and
cd $HOME/easygitianbuilder
./EasyGitianAdditional help is available in easygitianbuilder/USAGE.md or
cd $HOME/easygitianbuilder
./EasyGitian -hOpen a Terminal window
git clone https://github.com/mazaclub/easygitianbuilder
cd ./easygitianbuilder
./EasyGitianVagrant downloaded, verified, and installed, your apt-sources will be updated, and Virtualbox (and extension pack) will be installed via apt.
A Vagrant "base box" (debian-contribjessie) will be downloaded EasyGitian will build a Vagrant/Virtualbox VM and setup a build environment A build will begin.
To run another build, simply open a terminal and
cd $HOME/easygitianbuilder
./EasyGitianAdditional help is available in easygitianbuilder/USAGE.md or
cd $HOME/easygitianbuilder
./EasyGitian -hOperation in Windows10 works with Ubuntu in Windows Subsystem for Linux An Installer for WSL and Ubuntu is provided at https://raw.githubusercontent.com/mazaclub/easygitianbuilder/v0.1.0/Install_WSL_EasyGitian.ps1 Download that script, right click and run it a few times and Ubuntu will appear.
If you have WSL and ubuntu already, EasyGitian should work for you. Download this to your home directory
chmod +x Install_EasyGitian.shNow, however you've done the above run
source EasyGitian.env
./EasyGitianSee README-Windows.md
Gitian building is generally too difficult for most people to get done easily, and reliably. Instructions are less than clear if you don't have a background in most of the tech being used, and the tech though widely used isn't necessarily well understood by most users.
gitian-builder provides a Vagrantfile to pull cloud boxes from ubuntu for several different versions, and the stock bin/make-base-vm and libexec/make-clean-vm support virtualbox, but it's unclear the intended use or operation of these VMs.
LXC based building is an interim step - gitian-builder's gbuild script doesn't fully support bulding in virtualbox or other cloud-based VMs.
A similar project gitian-docker provides nearly the same functionality but is less portable due to docker's changing handling of host filesytem access on Windows and OSX. Vagrant orchestrated virtual machines seem more reliable on local systems than docker. Vagrant provides the ability to expand to several VPS providers (notably AWS, DigitalOcean, Vultr), and will allow for EasyGitian to spawn high-powered ephemeral build machines
EasyGitian will attempt to ensure that you have Vagrant and Virtualbox installed, and download and help you to install them if needed.
Tested with: Vagrant 2.1.4 VirtualBox 5.2.18
You'll then be given the opportunity to download Xcode from the Apple Developers site, and produce the SDK tarball required to build OSX version of coins.
Vagrant is used to create and launch a Virtualbox VM, and provision it with all your needs to build with gitian. A clean snapshot is saved for refreshing your build host, and a build is begun.
Environment variables needed to run the build are requested at the begining of the build, or may be made and saved prior to the second build.
Gitian building is done inside the VM in an lxc container VM.
Results, binaries, cached compiled dependencies are all saved in this directory for you.
EasyGitian Usage documented in USAGE.md Manual operation is possible, and outlined below
Debian, Ubuntu and CentOS are supprted directly by Vagrant Currently, only Debian based systems are supported in EasyGitian
Linux operation is similar but mostly untested
On debian stretch & jessie virtualbox is installed via apt On other debian based systems (including ubuntu for now) an attempt is made to download the .deb file for your host system and install via dpkg
EasyGitian will attempt to install Vagrant 2.1.4 and Virtualbox 5.2.18 on Debian9 Vagrant 2.0 and VirtualBox 5.1.28 will be installed on other debian based systems
