Deploy IoT applications with Balena Cloud and Arm Virtual Hardware
Introduction
Prepare a custom Balena OS image
Install Balena OS on AVH
Deploy an application to your device
Next Steps
Deploy IoT applications with Balena Cloud and Arm Virtual Hardware
Sign up for Balena Cloud
The free Balena Cloud service manages IoT devices and applications. You can deploy Balena apps without Balena Cloud using the open source OpenBalena project , but for simplicity this Learning Path uses the hosted service.
Navigate to the Balena Cloud Sign up form and create a new account. The free account lets you manage up to 10 devices with no cost. This Learning Path requires only one device.
After you’ve created your account, you can create a fleet. A fleet is a collection of devices serving as a single target for deploying applications.
Create a new fleet and name it AVH-Testing.
Download the Balena OS image
Add a device to your fleet. Navigate to the Devices section of your fleet and click on the Add Device button. This opens a dialog to create a custom device image.
Add Device dialog window
You can use the Raspberry Pi 4 device on Arm Virtual Hardware (AVH) as the new device.
Select Raspberry Pi 4 (using 64-bit OS) as the device type.
Select Development for the edition.
Leave the default values for everything else.
Download the image by clicking on the drop-down arrow on the right side of the Flash button and select Download balenaOS.
There’s no need to install Balena Etcher, the tool used to write SD cards.
The file is large so the download may take some time.
Convert the download to an AVH custom image
When the download finishes, you can convert the Balena OS device image into a custom AVH image that you can upload to the AVH service and run on a Raspberry Pi 4 device.
The conversion can be done using a Linux shell script.
Download the script
and save it as mkbalenaosimg.sh on your computer.
The conversion script requires a Linux environment with root access. If needed, copy the script and the Balena OS image .zip file to a Linux machine and log in to the machine. The zip and unzip commands are also required. Install them using your Linux package manager.
On a Linux machine, execute the script as root with the downloaded Balena OS image file as the only parameter:
bash ./mkbalenaosimg.sh balena-cloud-AVH-Testing-raspberrypi4-64-2.115.7+rev4-v14.11.2.img.zip
If successful, the conversion script creates a new file named balenaos_rpi4b.zip in the same directory.
If needed, copy the balenaos_rpi4b.zip file back to your original machine.
You are now ready to install Balena OS on a Raspberry Pi 4 in AVH.
