<title>Official Debian images</title>
|
|
<para>Since January 2015,
|
|
<link xlink:href="http://cdimage.debian.org/cdimage/openstack/">Debian
|
|
provides images for direct download</link>. They are now made at the
|
|
same time as the CD and DVD images of Debian. However, until Debian 8.0
|
|
(aka Jessie) is out, these images are the weekly built images of the
|
|
testing distribution.</para>
|
|
<para>If you wish to build your own images of Debian 7.0 (aka Wheezy, the
|
|
current stable release of Debian), you can use the package which is
|
|
used to build the official Debian images. It is named
|
|
<package>openstack-debian-images</package>, and it
|
|
provides a simple script for building them. This package is available
|
|
in Debian Unstable, Debian Jessie, and through the wheezy-backports
|
|
repositories. To produce a Wheezy image, simply run:
|
|
<screen><prompt>#</prompt> <userinput>build-openstack-debian-image -r wheezy</userinput></screen></para>
|
|
<para>If building the image for Wheezy, packages like
|
|
<package>cloud-init</package>, <package>cloud-utils</package> or
|
|
<package>cloud-initramfs-growroot</package> will be pulled from
|
|
wheezy-backports. Also, the current version of
|
|
<package>bootlogd</package> in Wheezy doesn't support logging to
|
|
multiple consoles, which is needed so that both the OpenStack
|
|
Dashboard console and the <command>nova console-log</command>
|
|
console works. However, a <link
|
|
xlink:href="http://archive.gplhost.com/debian/pool/juno-backports/main/s/sysvinit/bootlogd_2.88dsf-41+deb7u2_amd64.deb">
|
|
fixed version is available from the non-official GPLHost
|
|
repository</link>. To install it on top of the image, it is possible
|
|
to use the <option>--hook-script</option> option of the
|
|
<command>build-openstack-debian-image</command> script, with this
|
|
kind of script as parameter:
|
|
<programlisting language="bash">#!/bin/sh
|
|
|
|
cp bootlogd_2.88dsf-41+deb7u2_amd64.deb ${BODI_CHROOT_PATH}
|
|
chroot ${BODI_CHROOT_PATH} dpkg -i bootlogd_2.88dsf-41+deb7u2_amd64.deb
