Besides Ubuntu, MAAS allows users to deploy different operating systems, such as CentOS. Ubuntu Advantage customers can additionally deploy Red Hat Enterprise Linux (RHEL), OpenSUSE, SLES, Window Server and Windows HyperV.
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 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)
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 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>
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:
- SLES 11 and SLES 12
- Redhat Enterprise Linux 7 (RHEL7)
The MAAS Image Builder is a script that allows users to generate their own
maas-image-builder only supports the generation of CentOS
and RHEL images. To install
maas-image-builder, please follow the
sudo apt-add-repository ppa:maas-maintainers/stable sudo apt-get install maas-image-builder
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,
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
