第 3 章 Deploying a RHEL image as a compute instance on Azure


To use a RHEL image on Microsoft Azure, convert the image to an Azure-compatible format and deploy a VM from the image to run as an Azure Compute VM. To create, customize, and deploy a RHEL virtual hard drive (VHD) as an Azure disk image format, you can use one of the following methods:

Before you begin, make sure to complete following steps:

3.1. Available RHEL image types for public cloud

To deploy your RHEL virtual machine VM on a certified cloud service provider (CCSP), you can use several options. The following table lists the available image types, subscriptions, considerations, and sample scenarios for the image types.

注意

To deploy customized ISO images, you can use RHEL image builder. With RHEL image builder, you can create, upload, and deploy these custom images specific to your chosen CCSP. For details, see Composing a Customized RHEL System Image.

Image typesSubscriptionsConsiderationsSample scenario

Deploy a Red Hat gold image

Use your existing Red Hat subscriptions

The subscriptions include the Red Hat product cost and support for Cloud Access images, while you pay the CCSP for all other instance costs

Select a Red Hat gold image on the CCSP. For details on gold images and how to access them on the CCSP, see the Red Hat Cloud Access Reference Guide

Deploy a custom image that you move to the CCSP

Use your existing Red Hat subscriptions

The subscriptions includes the Red Hat product cost and support for custom RHEL image, while you pay the CCSP for all other instance costs

Upload your custom image and attach your subscriptions

Deploy an existing RHEL based custom machine image

The custom machine images include a RHEL image

You pay the CCSP on an hourly basis based on a pay-as-you-go model. For this model, on-demand images are available on the CCSP marketplace. The CCSP provides support for these images, while Red Hat handles updates. The CCSP provides updates through the Red Hat Update Infrastructure (RHUI)

Select a RHEL image when you launch an instance on the CCSP cloud management console, or choose an image from the CCSP marketplace.

重要

You cannot convert an on-demand instance to a custom RHEL instance. For migrating from an on-demand image to a custom RHEL bring your own subscription (BYOS) image, do the following:

  • Create a new custom RHEL instance, then migrate data from your on-demand instance.
  • When you complete data migration, terminate the on-demand instance to avoid additional billing.
