= Creating the {op-system} image for restricted network installations
|
|
|
|
Download the {op-system-first} image to install {product-title} on a restricted network
|
|
ifdef::osp[{rh-openstack-first}]
|
|
ifdef::vsphere[VMware vSphere]
|
|
environment.
|
|
|
|
.Prerequisites
|
|
|
|
* Obtain the {product-title} installation program. For a restricted network installation, the program is on your mirror registry host.
|
|
|
|
.Procedure
|
|
|
|
. Log in to the Red Hat Customer Portal's https://access.redhat.com/downloads/content/290[Product Downloads page].
|
|
|
|
. Under *Version*, select the most recent release of {product-title} {product-version} for RHEL 8.
|
|
+
|
|
[IMPORTANT]
|
|
====
|
|
The {op-system} images might not change with every release of {product-title}.
|
|
You must download images with the highest version that is less than or equal to
|
|
the {product-title} version that you install. Use the image versions that match
|
|
your {product-title} version if they are available.
|
|
====
|
|
|
|
ifdef::osp[]
|
|
. Download the *{op-system-first} - OpenStack Image (QCOW)* image.
|
|
endif::osp[]
|
|
ifdef::vsphere[]
|
|
. Download the *{op-system-first} - vSphere* image.
|
|
endif::vsphere[]
|
|
|
|
ifdef::osp[]
|
|
. Decompress the image.
|
|
+
|
|
[NOTE]
|
|
====
|
|
You must decompress the image before the cluster can use it. The name of the downloaded file might not contain a compression extension, like `.gz` or `.tgz`. To find out if or how the file is compressed, in a command line, enter:
|
|
|
|
----
|
|
$ file <name_of_downloaded_file>
|
|
----
|
|
|
|
====
|
|
|
|
. Upload the image that you decompressed to a location that is accessible from the bastion server, like Glance. For example:
|
|
+
|
|
----
|
|
$ openstack image create --file rhcos-44.81.202003110027-0-openstack.x86_64.qcow2 --disk-format qcow2 rhcos-${RHCOS_VERSION}
|
|
----
|
|
+
|
|
[IMPORTANT]
|
|
====
|
|
Depending on your {rh-openstack} environment, you might be able to upload the image in either link:https://access.redhat.com/documentation/en-us/red_hat_openstack_platform/15/html/instances_and_images_guide/index[`.raw` or `.qcow2` formats]. If you use Ceph, you must use the `.raw` format.
|
|
====
|
|
+
|
|
[WARNING]
|
|
====
|
|
If the installation program finds multiple images with the same name, it chooses one of them at random. To avoid this behavior, create unique names for resources in {rh-openstack}.
|
|
====
|
|
endif::osp[]
|
|
ifdef::vsphere[]
|
|
. Upload the image you downloaded to a location that is accessible from the bastion server.
|
|
endif::vsphere[]
|
|
|
|
The image is now available for a restricted installation. Note the image name or location for use in {product-title} deployment.
