NAME
build-openstack-debian-image - build a Debian image to be used with OpenStack
SYNOPSIS
build-openstack-debian-image --release|-r <wheezy|jessie|stretch|buster|bullseye> [
OPTIONS ]
DESCRIPTION
The build-openstack-debian-image shell script will build a Debian image which can be used
in an OpenStack IaaS cloud. The resulting (Qcow2 and raw images) contains
initramfs-growroot so that the root partition will be resized (during the initramfs phase,
before mouting anything) to match the flavor selected when using "nova boot". Later on
during the boot process, cloud-init will resize the root partition on the fly (resize is
performed when the partition is already mounted read-write, since recent kernel allow that
for ext3).
Cloud-init is setup to use an Ec2 metadata server, which is what OpenStack is compatible
with. A "debian" (configurable with the use of the --login option) user will be used to
receive the ssh key from the user data blob. This user is setup without a password (eg:
adduser --disabled-password). Once logged as this "debian" user in your new virtual
machine, you can "sudo" to root from that user, without needing a password. The root
password is "password" by default, and ssh into the root user without using an ssh keypair
is disabled by default (PermitRootLogin without-password is set in /etc/ssh/sshd_config).
PARAMETERS
--release|-r wheezy|jessie|stretch|buster|bullseye
Sets the release name to be installed. Currently only 5 values a possible: wheezy
or jessie or stretch or buster or bullseye.
At the time of writing, bullseye is only here to prepare the future, and will not
work until it effectively becomes the new testing.
OPTIONS
--extra-packages|-e PACKAGE,PACKAGE,...
Select the PACKAGE you want to add to the image default is: bash-
completion,joe,most,screen,less,vim,bzip2 Note that this list of extra packages
isn't used if you use the --minimal option.
--debootstrap-url|-u <debootstrap-debian-mirror>
Select the URL of the Debian mirror to use to perform the debootstrap. For example:
http://ftp.fr.debian.org/debian
--debootstrap-keyring-file|-k <path-to-keyring>
Use the specified keyring file, and not the official debian archive keyring, when
verifying packages. This is useful when using an unofficial package repository
(e.g. a self-hosted aptly)
--copy-debootstrap-keyring-file
Copy the keyring file specified by --debootstrap-keyring-file into
/etc/apt/trusted.gpg.d and /usr/share/keyrings in the generated image. Note that
the prefered way to install and manage a keyring is to install it as a package
using --extra-packages.
--boot-manager|-bm <grub|syslinux>
Select what type of boot manager to use inside the image. The default is Grub, but
you can as well decide to use syslinux if you prefer.
--boot-type|-bt <mbr|uefi>
Select how to boot the image: using legacy MBR-style (aka BIOS or CSM) boot, or
UEFI. The default is mbr. Selecting uefi requires the use of Grub as the boot
manager, and will set up an extra EFI System Partition inside the image to support
UEFI boot.
--architecture|- <amd64|arm64>
Select the architecture to target for the output image. This will not cross build
for that architecture, but will pick the right architecture-specific components.
Supported options are "amd64" and "arm64"; "amd64" is default.
--sources.list-mirror|-s <source-list-mirror>
URL to use when building the sources.list inside the chroot. If this option is
omitted, then the global httpredir.debian.org redirector is used. For example, you
can use: http://ftp.fr.debian.org/debian
--minimal
Without this option, the following packages will also be installed: bash-completion
(and /etc/bash.bashrc will be setup to use bash-completion), joe (the text editor),
most, GNU screen, less and vim. If you believe that more things should be added in
the non-minimal image, suggestions are welcome.
--azure|-az
Build an image for the Microsoft Azure cloud. Note that this option is incompatible
with the --automatic-resize|-ar option, which will be ignored.
--image-size|-is <image-size>
Select the image size (default to 2 GBytes if this option is omitted). Only useful
if you need to use a custom script hook (see below).
--automatic-resize|-ar
Reduce the image to the minimum HDD size possible. The partition of the image will
be first shrinked with resize2fs -M, then the space it takes will be used to do a
2nd resize2fs adding a bit of extra space for the operating system to write runtime
data (see below). Since this option takes a lot of time, it is disabled by default.
--automatic-resize-space|-ars <supplementary-space>
Size of the supplementary space added to the partition after it is resized to the
minimum. If this option is omitted, then 50G is used. If --automatic-resize isn't
used, then it is useless to set this option, which will be ignored.
--login|-l <user-login>
Change the login name (default to debian) for the user created by Cloud-Init.
--password|-p <root-password>
Defines a default root password for your image. This option is dangerous, first
because it will show the root password to the user of the computer building the
image if using "ps", then also because it is best to not set a default root
password at all if possible. However, this option is still there, because
sometimes, you need to be able to debug your image, and login through the web
console of horizon. In a production environment, do not use this option.
--octavia-agent
Install the Octavia agent in order to build an Octavia Amphorae image, that will be
used for HA proxy based Load Balancer as a Service.
--manila-agent
Install the Manila agent in order to build OpenStack Manila share image.
--trove-agent
Install the Trove agent in order to build the OpenStack Trove image.
--extrepo <openstack-release>
Setup the OpenStack extrepo repository. This is mainly useful when the
--octavia-agent option is use, so the unofficial OpenStack backports repositories
can be used to setup the agent.
--kernel-from-backports <yes/no>
If set to yes, install the kernel from official Debian backports.
--editor <nano,vim>
List of editors to install in image.
--default-editor </bin/nano, /usr/bin/joe, /usr/bin/vi>
Set default alternative editor
--hook-script|-hs <hook-script>
If you wish to further customize the generated cloud image, you can use a hook
script. When called, build-openstack-debian-image will fill up some BODI_*
environment variable for the hook script to use as per below:
BODI_CHROOT_PATH path where the image is mounted
BODI_RELEASE name of the Debian release that is being bootstraped
--newer-qemu
Do not use the -o compat=0.10 option when converting to raw, and also, use -p -W -m
8 (ie: multi-thread + progress indicator convert).
EXAMPLE
Here is an example with the short parameter names:
build-openstack-debian-image -u http://ftp.fr.debian.org/debian -s
http://ftp.fr.debian.org/debian -is 5 -e libapache2-mod-php5 -hs ~/customize-my-image -ar
-ars 100
And the same but with long names for options:
build-openstack-debian-image --debootstrap-url http://ftp.fr.debian.org/debian
--sources.list-mirror http://ftp.fr.debian.org/debian --image-size 5 --extra-packages
libapache2-mod-php5 --hook-script ~/customize-my-image --automatic-resize
--automatic-resize-space 100
