Red Hat creates tools to help you manage the lifecycle of your Red Hat Enterprise Linux (RHEL) edge devices easily.  Edge management in the Red Hat Hybrid Cloud Console makes it easy to standardize, deploy and enhance the security posture throughout the lifecycle of all your edge devices. 

What makes RHEL different on edge devices? RHEL provides edge-optimized features that address deployment on systems with small resource footprints, scaling to hundreds or thousands of devices (or more). In particular, RHEL provides the following:

  • Custom OS image generation

  • Remote device update mirroring

  • Efficient over-the-air updates

  • Intelligent rollbacks

  • FIDO Device Onboard (FDO)

  • Edge management

In this article, I show you how to quickly deploy RHEL on an edge device with the Red Hat edge management service available on the Hybrid Cloud Console. You can also follow along through the Edge Management Lab.

Create an image for your edge device

When you first log into your Hybrid Cloud Console, navigate to the “Edge Management” menu.


Click the “Create new image” button.


The “Create image” menu will appear. Here we’ll create a new OS image to be installed on our edge device.

  1. Name the image. For this example, we’ll create a new image called “acme” for our fictional company

  2. Click the “Next” button


On the next menu, there is nothing to be done since we’re happy with the default setting of RHEL9 and we want to create a RHEL for Edge Installer iso. Click the “Next” button.


In the “Device registration” menu, we’ll fill in the details required to let us log into our edge device after it has been provisioned.

  1. Enter a username

  2. Copy the public key from your SSH Key Pair. For more information on generating an SSH Key Pair, read this

  3. Click the “Next” button


Click “Next” to skip to the "Additional packages" menu.


In the “Additional packages” menu, add the “vim-enhanced” package to the image. This menu is where we customize the software we want to install in our image.

  1. Add “vim-enhanced”

  2. Click “Next”


Finally, review the configuration of the image. Click the “Create image” button to create the image.


You’ll be taken to a dashboard showing your image build. This process can take around 15 minutes.


Installing the image

When the image build is complete, download the image to your local machine.

  1. Click on the kebab button

  2. Select “Download”

Save the image.

You can now write the image to a USB flash drive where it will automatically install itself on whatever computer you plug the flash drive into. For more information on writing ISO-formatted images to USB flash drives, see here.

In this example, we will load the image into a virtual machine. The Edge Management Lab provides instructions on how to do this on a RHEL host. The duration of the installation depends on the compute power of your host. You should see output like this:


Eventually, your host will reboot to complete the installation.

Now we’ll log back into the host and register it with the Hybrid Cloud Console. 

Log into your host and run the following command as root:

rhc connect --username <hybrid cloud console admin user for your org> --password <password>


Next, run the following command to collect and upload the information to the Hybrid Cloud Console.

insights-client --register

Go back to the Hybrid Cloud Console. The new edge device will be listed in the inventory (Edge Management > Inventory > Systems).


Let’s add a new package to the edge device from the Hybrid Cloud Console. Click on “Manage Images”. Look for the image and click on the kebab button to the right.

Click on "Update image".


Click "Next" until you arrive at the "Additional packages" menu. We’ll add a bunch of packages (nginx, php, tmux, wireshark). When you’re done, click "Next".


Now click on “Update image”.


Wait for the image to build.

Once the image has been built, go back to “Systems” in the “Inventory” menu. Click on the kebab button and select “Update” to update your edge device.


A menu will pop up asking you to confirm that you wish to update the edge device. Click on “Update system” to do so. 


The edge device will install the update and reboot, completing the update process. To check this, log into the device and enter the following command:

rpm-ostree status

You’ll see the following while the upgrade is taking place:


Here’s what it looks like when the upgrade is complete and the edge device has rebooted:


If you’d like to roll back to the previous deployment, just run rpm-ostree rollback:


Remember to reboot the device.
