Hosts > Installation Media
Installation media are packages used to install the base operating system during the provisioning process.
An installation medium in orcharhino represents the installation files for one or more operating systems, which must be accessible via the network, either via an URL or an NFS server location.
It is usually either a mirror or a CD or DVD image.
Pointing the URL of the installation medium to a local copy (e.g.
http://orcharhino.example.com/pub/installation_media/) may improve provisioning time and reduce network load.
Every operating system depends on exactly one path of an installation medium, whereas installation media paths may serve different operating systems at the same time.
For CentOS and RHEL, this can be done by using the keywords
$minor in the path, which will be filled in when accessing the URL.
Debian, Ubuntu, and SLES do not support such variables.
Installation media for multiple versions of Debian may be bundled in one path, e.g. a repository containing packages for both Debian 9 Stretch as well as Debian 10 Buster.
This also works for Ubuntu.
Refer to the orcharhino installation guide on how to add installation media for SLES and Oracle Linux.
The Create Medium button (1) allows you to create a new installation media.
The list of installation media (2) displays all currently available installation media. Existing installation media can be edited by clicking their name.
Clicking the Delete button (3) allows you to delete an installation media.
The list of displayed installation media is sensitive to context.
This means only those installation media associated with the currently selected context (
Select any organization and any location from the context menu to see all existing installation media. For the sake of users with restricted access, make sure installation media are associated with the proper organizations and locations.
The Name field (1) should be unique and meaningful, e.g.
The Path field (2) specifies the location of the installation media. It supports the inclusion of variables such as
$release. Using variables, a single installation medium entry in orcharhino can be used to point to different versions of the installation media for a single distribution. This field would typically be the URL to an internet mirror for the relevant Linux distribution (e.g.
http://mirror.example.com/pub/centos/$version/os/$arch) or an NFS path to a copy of an installation disk image (e.g.
The Operating System Family drop down menu (3) assigns an operating system family to the installation media.
Clicking Submit (4) saves your changes to orcharhino.
Remember to also fill out the Location and Organization context (5) for the new installation media.
A clean installation of orcharhino should already include some preconfigured installation media.
Editing an installation media is essentially the same as creating an installation media, with the difference that fields will be prefilled with the settings of the installation media being edited.
