Operating Systems Support
=========================
.. note::
This feature is available in MAAS versions 1.7 and above.
Besides Ubuntu, MAAS allows users to deploy different operating
systems, such as CentOS. Ubuntu Advantage customers can
additionally deploy Redhat Enterprise Linux (RHEL), OpenSUSE, SLES,
Window Server and Windows HyperV.
Generated Images vs. Custom Images
----------------------------------
MAAS supports two different classes of OS images, `Generated images`
and `Custom images`.
`Generated images` are images of the OS' that MAAS team fully
supports. Currently supported OS' are CentOS and Windows.
`Custom images` are images that MAAS can deploy, but may have been
customized and differ from those that the MAAS team supports. Custom
images can include any Ubuntu, CentOS or Windows image. Additionally,
Redhat Enterprise Linux (RHEL), OpenSUSE and SLES images also fall
under this category.
Installing MAAS Images
----------------------
Installing Generated Images
^^^^^^^^^^^^^^^^^^^^^^^^^^^
Installing MAAS Generated Images (CentOS or Windows) can be done with
the command::
$ maas admin boot-resources create name=<os/series>
architecture=<architecture> [filetype=ddtgz]
content@=<image-name>
The list of supported Operating Systems under `Generated Images` is:
* CentOS 6.5 (centos/centos65)
* CentOS 7 (centos/centos7)
* Windows Server 2012 (windows/win2012)
* Windows Server 2012 R2 (windows/win2012r2)
* Windows Hyper-V (windows/win2012hv)
* Windows Hyper-V R2 (windows/win2012hvr2)
Examples::
$ maas admin boot-resources create name=centos/centos7
architecture=amd64/generic content@=centos7-amd64-root-tgz
$ maas admin boot-resources create name=windows/win2012
architecture=amd64/generic filetype=ddtgz
content@=win2012-amd64-ddtgz
Installing Custom Images
^^^^^^^^^^^^^^^^^^^^^^^^
Installing custom images require the user to specify a unique
identifier for the OS and Release, as well as the title of the
Image::
$ maas admin boot-resources create name=custom/<os-release-id>
title=<title> architecture=amd64/generic content@=<image-name>
Examples::
$ maas admin boot-resources create name=custom/rhel7
title="RedHat Enterprise Linux 7" architecture=amd64/generic
content@=rhel7-amd64-root-tgz
The list of tested Operating Systems under `Custom Images` is:
* OpenSUSE
* SLES 11 and SLES 12
* Redhat Enterprise Linux 7 (RHEL7)
MAAS Image Builder
------------------
The MAAS Image Builder is a script that allows users to generate their
own images. However, ``maas-image-builder`` only supports the generation
of CentOS and RHEL images. To install ``maas-image-builder``, please
follow the instructions::
$ sudo apt-add-repository ppa:maas-maintainers/stable
$ sudo apt-get install maas-image-builder
Creating and Installing CentOS MAAS Images
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
.. note::
Supported CentOS versions are CentOS 6.5 (centos65) and CentOS 7 (centos7).
To create a MAAS CentOS image, no ISO is needed as all of the required
software to create the image is downloaded (from CentOS repositories) as part
of the image generation process. To create the MAAS CentOS image,
``maas-image-builder`` can be used as::
$ maas-image-builder -a amd64 -o centos7-amd64-root-tgz centos --edition 7
The created image, ``centos7-amd64-root-tgz``, needs to be uploaded into the
MAAS Region Controller. This image will be listed under the `Generated` Image
Section in the `MAAS Image` page. This image can be uploaded with::
$ maas admin boot-resources create name=centos/centos7
architecture=amd64/generic content@=./build-output/centos7-amd64-root-tgz
