What Happened?
- You want to know how to choose an appropriate image for your certified hardware.
Environment
- F5® Distributed Cloud
- Site Management
Answer/Resolution
Choosing an appropriate image for your certified hardware will ensure that your site is deployed properly and operates as expected. Here are some basic rules:
- Use an image from the correct vendor. In other words, use a Dell image for a Dell, use an AWS image for deployment in AWS, etc.
- Generic images that include a wlan0 device should be used only for devices with wifi. Here is a list of supported generic images:
-
generic-single-nic
-
generic-single-nic-volstack-combo
-
generic-multi-nic-voltmesh
-
- Choose an image with the correct number of interfaces. If you choose an image with one interface (eth0) for a machine with 2 interfaces, the other interface will not be provisioned, and this may cause an error.
Additional Information
In the F5® Distributed Cloud Console (Console), select the Cloud and Edge Sites service. Then in the left navigation pane, select Manage->Site Management->Certified Hardware.
This shows the list of certified hardware with three columns showing additional information.
The Name column provides the name of the hardware and gives hints for the intent of the image. For instance, kvm-voltmesh would be intended for a Kernel-based Virtual Machine (KVM) with a single network interface card (NIC) with Distributed Cloud Mesh. You can see the description for the name by clicking the right-arrow next to the name to see the JSON specifications.
The Devices column shows which devices are used for the hardware. Multiple devices will be shown as either a list, eth0, eth1, as an array, ver [0 - 3], or both. You can get more details about the devices for the hardware by looking in the get_spec->devices object in the JSON.
The Images column shows the list of images to use with the hardware. These images correspond to the images you can select or download (depending on the hardware) on the Certified Hardware Images page. The example below is for generic-single-nic, which specifies three images, one for Amazon Web Services (AWS), one for the Intel NUC, and one for Microsoft Azure.
