From a98b8707dc5606a5c119a123b1b66d5e7ab5a815 Mon Sep 17 00:00:00 2001 From: Giuseppe Mazzotta Date: Tue, 3 Jun 2014 11:40:24 +0200 Subject: [PATCH] Some documentation fixes + link to my Docker/LXC guide I added a link to my guide about using docker containers + LXC (I am planning to maintain this at work for future bitcoin versions), then I mentioned other virtualization options (KVM, LXC). This commit includes a fix issue for documentation issue #4269 that consists in telling users to checkout correct bitcoin version before using the gitian descriptors (otherwise all hell can break loose). Also, I replaced URL for Debian 7.4 ISO with a correct one and added link to official Debian ISO sources. --- doc/gitian-building.md | 45 +++++++++++++++++++++--------------------- 1 file changed, 23 insertions(+), 22 deletions(-) diff --git a/doc/gitian-building.md b/doc/gitian-building.md index 544bbc12c..378a45eda 100644 --- a/doc/gitian-building.md +++ b/doc/gitian-building.md @@ -34,19 +34,22 @@ Table of Contents - [Signing externally](#signing-externally) - [Uploading signatures](#uploading-signatures) +Preparing the Gitian builder host +--------------------------------- + +The first step is to prepare the host environment that will be used to perform the Gitian builds. +In this guide it is explained how to set up the environment, and how to get the builds started. + +Debian Linux was chosen as the host distribution because it has a lightweight install (in contrast to Ubuntu) and is readily available. +Any kind of virtualization can be used, for example: +- [VirtualBox](https://www.virtualbox.org/), covered by this guide +- [KVM](http://www.linux-kvm.org/page/Main_Page) +- [LXC](https://linuxcontainers.org/), see also [Gitian host docker container](https://github.com/gdm85/tenku/tree/master/docker/gitian-bitcoin-host/README.md). + +You can also install on actual hardware instead of using virtualization. + Create a new VirtualBox VM --------------------------- - -The first step is to create a new Virtual Machine, which will be explained in -this section.
