This feature is available in MAAS versions 1.7 and above.
13
Besides Ubuntu, MAAS allows users to deploy different operating
14
systems, such as CentOS. Ubuntu Advantage customers can
15
additionally deploy Redhat Enterprise Linux (RHEL), OpenSUSE, SLES,
16
Window Server and Windows HyperV.

Generated Images vs. Custom Images
20
----------------------------------
22
MAAS supports two different classes of OS images, `Generated images`
25
`Generated images` are images of the OS' that MAAS team fully
26
supports. Currently supported OS' are CentOS and Windows.
28
`Custom images` are images that MAAS can deploy, but may have been
29
customized and differ from those that the MAAS team supports. Custom
30
images can include any Ubuntu, CentOS or Windows image. Additionally,
31
Redhat Enterprise Linux (RHEL), OpenSUSE and SLES images also fall

Installing Generated Images
39
^^^^^^^^^^^^^^^^^^^^^^^^^^^
41
Installing MAAS Generated Images (CentOS or Windows) can be done with
44
$ maas admin boot-resources create name=<os/series>
45
architecture=<architecture> [filetype=ddtgz]
48
The list of supported Operating Systems under `Generated Images` is:
50
* CentOS 6.5 (centos/centos65)
51
* CentOS 7 (centos/centos7)
52
* Windows Server 2012 (windows/win2012)
53
* Windows Server 2012 R2 (windows/win2012r2)
54
* Windows Hyper-V (windows/win2012hv)
55
* Windows Hyper-V R2 (windows/win2012hvr2)
59
$ maas admin boot-resources create name=centos/centos7
60
architecture=amd64/generic content@=centos7-amd64-root-tgz
62
$ maas admin boot-resources create name=windows/win2012
63
architecture=amd64/generic filetype=ddtgz
64
content@=win2012-amd64-ddtgz
66
Installing Custom Images
67
^^^^^^^^^^^^^^^^^^^^^^^^
69
Installing custom images require the user to specify a unique
70
identifier for the OS and Release, as well as the title of the
73
$ maas admin boot-resources create name=custom/<os-release-id>
74
title=<title> architecture=amd64/generic content@=<image-name>
78
$ maas admin boot-resources create name=custom/rhel7
79
title="RedHat Enterprise Linux 7" architecture=amd64/generic
80
content@=rhel7-amd64-root-tgz
82
The list of tested Operating Systems under `Custom Images` is:
86
* Redhat Enterprise Linux 7 (RHEL7)
92
The MAAS Image Builder is a script that allows users to generate their
93
own images. However, ``maas-image-builder`` only supports the generation
94
of CentOS and RHEL images. To install ``maas-image-builder``, please
95
follow the instructions::
97
$ sudo apt-add-repository ppa:maas-maintainers/stable
98
$ sudo apt-get install maas-image-builder
101
Creating and Installing CentOS MAAS Images
102
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
106
Supported CentOS versions are CentOS 6.5 (centos65) and CentOS 7 (centos7).
109
To create a MAAS CentOS image, no ISO is needed as all of the required
110
software to create the image is downloaded (from CentOS repositories) as part
111
of the image generation process. To create the MAAS CentOS image,
112
``maas-image-builder`` can be used as::
114
$ maas-image-builder -a amd64 -o centos7-amd64-root-tgz centos --edition 7
116
The created image, ``centos7-amd64-root-tgz``, needs to be uploaded into the
117
MAAS Region Controller. This image will be listed under the `Generated` Image
118
Section in the `MAAS Image` page. This image can be uploaded with::
120
$ maas admin boot-resources create name=centos/centos7
121
architecture=amd64/generic content@=./build-output/centos7-amd64-root-tgz
