How to access Red Hat update servers (RHUI 3)
UKCloud has implemented a Red Hat Update Infrastructure (RHUI) to provide automatic updates to our Red Hat customers in the Assured OFFICIAL and Elevated OFFICIAL security domains. The benefits over the existing system are the reliable availability of patch updates and Red Hat approved OS templates.
Before you attempt to establish a connection to RHUI Content Delivery Systems (CDS), you need to make sure your virtual machines (VMs) can communicate with the RHUI, which exists outside of your cloud organisation. This may involve editing the NAT and firewall settings within your edge gateway to allow traffic to traverse into your virtual data centre (VDC). For how to do this, see the articles for creating NAT and firewall rules.
This article is intended for customers who have migrated their systems to use RHUI v3.
New Red Hat VM templates
Certain Red Hat templates within the UKCloud public catalogue are automatically configured to receive updates from UKCloud's RHUI. The templates are:
RHEL6.Latest - UKCloud-RHEL6
RHEL7.Latest - UKCloud-RHEL7
RHEL8.Latest - UKCloud-RHEL8
These templates have the following properties:
Red Hat Update Infrastructure enabled for standard packages
VMware Tools / Guest Customization enabled
60GB disk space / 1 x vCPU / 2GB RAM (default, adjust as required)
To configure the root password for the VM, Guest Customisation MUST be run.
You can adjust the VM properties as required and you'll be billed per the standard VM sizes as described in the UKCloud Pricing Guide. You will not be billed on additional storage until you reach the 60GiB of provisioned disk space.
Old Red Hat VM templates
If you've already deployed a Red Hat VM using the old templates, you can configure it to access the latest RHUI by following the steps in How to install Red Hat Update Infrastructure (RHUI) on an existing virtual machine (RHUI v3).
High Availability (HA) is a premium Red Hat service, therefore you'll need to notify UKCloud for access to HA repositories or bring your own licenses to support this service. If required, we can provide access to additional repositories such as Scalable File System, Load Balancer or Resilient Storage. To access these services, raise a Service Request via the My Calls section in the UKCloud Portal.
