Did you know? In the latest Docker 19.03 Release, a new flag –gpus have been added for docker runnvidia-docker has already adopted this feature (see github), but deprecated --runtime=nvidia.
Last Dockercon, I met with a four-wheeled knee-high tiny cute food delivery robot called Kiwibot. Built by KiwiCampus Inc., Kiwibot is the robot counterpart of the pizza delivery person. Thanks to Dockercon for bringing this amazing piece of technology in-house for distributing swags, stickers, chocolates and goodies.
What’s so cool about Kiwibots?
Just open up your Wiki app and place an order for food. When you place an order online(facility to choose a participating restaurant), you get the option of delivery via Kiwi. Once you choose, one of the company’s fleet of super cool robots with insulated, locking storage compartments will swing by the place, your order is put within, and it brings it to your location. You can even watch the last bit live from the robot’s perspective as it rolls up to your place. Amazing, isn’t it?
Well, the super cute make and structure of these kiwibots looked interesting to me BUT what fascinated me really is the technology behind these small robots. A Kiwibot is equipped with six cameras and GPS to deliver the order at the right place. Nice ! Now here comes the best part. Only the person who has ordered will be able to open the Kiwibot and retrieve the order through the app which means it is intelligent enough to do object detection and analytics too. Interesting !!
Tell me more…
I went through the technology stack and was really amazed to learn that it uses NVIDIA Jetson TX2 system for all of the AI processing, imaging, and related computing tasks(see picture below). Jetson TX2 is a credit card-sized platform that puts AI computing to work in the world all around us. Obviously, GPU-based deep learning has given computers the ability to understand — and react to — the data streaming in from all these devices in uncanny new ways. Both through training — which creates smart systems — and through inference — which creates systems that are able to react intelligently to the world around them in real time.
Before I loose my patience any further, the day finally arrived when I was lucky enough to hold the most powerful AI platform in my hand.
The NVIDIA® Jetson Nano™ Developer Kit is purely an AI computer. It is a small, powerful computer that lets you run multiple neural networks in parallel for applications like image classification, object detection, segmentation, and speech processing. All in an easy-to-use platform that runs in as little as 5 watts. It is perfect for makers, learners, and developers that brings the power of modern artificial intelligence to a low-power, easy-to-use platform.
Some Really Useful Facts around NVIDIA Jetson Nano..
- There are 2 ways to power a Jetson Nano – either using Micro USB power supplies Or by using Barrel Jack 5V 4A(20W) power supplies. I don’t recommend using the normal micro-USB adapter which you use for mobile. Buy here if you are in India
- Jetson Nano works in 2 model – MAXN and 5 Watt. By default the Nano works at MAXN(10 Watt mode). If using a Micro USB adapter you should change that immediately to 5W mode. When using the barrel jack to connect a 5V 4A (20W) power supply, you should set the Nano into 10 Watt mode to allow maximum power usage. Learn more
- No WiFi module is shipped with this board. A user can easily get a wifi dongle or module that’s already been certified and plug it in for the usage
- Jetson Nano is supported by the comprehensive NVIDIA® JetPack™ SDK, and has the performance and capabilities needed to run modern AI workloads. JetPack includes:
- Jetson Nano comes with Full desktop Linux with NVIDIA driver, AI and Computer Vision libraries and APIs. developer tools & documentation and sample code.
Installing Docker 19.03 on NVIDIA Jetson Nano
Early this May 2019, I wrote a blog post around Docker 19.03 which comes with a new –gpus CLI plugin capability. With the recent 19.03 GA Release, now you don’t need to spend time in downloading the NVIDIA-DOCKER plugin and rely on nvidia-wrapper to launch GPU containers. All you can now use –gpus option with docker run CLI to allow containers to use GPU devices seamlessly.
As I wanted to try running CUDA containers on Jetson Nano, I couldn’t wait to update it to 19.03 release so as to see how containers can leverage the existing GPU device. Under this blog post, I will showcase how to get started with Docker 19.03 on Jetson Nano.
Preparing Jetson Nano
- Unboxing Jetson Nano Pack
- Preparing your microSD card
To prepare your microSD card, you’ll need a computer with Internet connection and the ability to read and write SD cards, either via a built-in SD card slot or adapter.
- Download the Jetson Nano Developer Kit SD Card Image, and note where it was saved on the computer.
- Write the image to your microSD card( atleast 16GB size) by following the instructions below according to the type of computer you are using: Windows, Mac, or Linux. If you are using Windows laptop, you can use SDFormatter software for formatting your microSD card and Win32DiskImager to flash Jetson Nano Image. In case you are using Mac, you will need Etcher software.
- To prepare your microSD card, you’ll need a computer with Internet connection and the ability to read and write SD cards, either via a built-in SD card slot or adapter
The Jetson Nano SD card image is of 12GB(uncompressed size).
Next, It’s time to remove this tiny SD card from SD card reader and plugin it to Jetson Board to let it boot.
Wow ! Jetson Nano comes with 18.09 by default
Yes, you read it correct. Let us try it once. First we will verify OS version running on Jetson Nano.

Hello from Docker!
This message shows that your installation appears to be working correctly.
To generate this message, Docker took the following steps:
1. The Docker client contacted the Docker daemon.
2. The Docker daemon pulled the "hello-world" image from the Docker Hub.
(arm64v8)
3. The Docker daemon created a new container from that image which runs the
executable that produces the output you are currently reading.
4. The Docker daemon streamed that output to the Docker client, which sent it
to your terminal.
To try something more ambitious, you can run an Ubuntu container with:
$ docker run -it ubuntu bash
