Power Up Your Edge Computing: Easily Install Docker Compose on Advantech RSB-3720!

Are you using the Advantech RSB-3720 development board with Yocto 4.0 for edge computing development? Want to make your application deployment more flexible and efficient? Today, we’ll show you how to easily install Docker Compose on the RSB-3720, making your multi-container application management a breeze!

What is Docker Compose? Why Do You Need It?

#

Simply put, Docker Compose is like an orchestra conductor, coordinating multiple Docker containers to work together. Imagine your application needs a database, web server, caching system, and more, each running in an independent Docker container. Without Docker Compose, you would need to manually start and configure these containers one by one, which is very cumbersome.

With Docker Compose, you only need a simple docker-compose.yml file, defining the configuration and dependencies of all containers, and then start it with one click. All containers will automatically run according to your settings! This not only simplifies the deployment process but also makes your application easier to scale and maintain.

In the field of edge computing, Docker Compose has a wide range of applications. For example, you can use it to deploy a complete solution including sensor data collection, analysis, and visualization, or quickly build an environment for machine learning model training and inference.

Why Does Yocto System Require Manual Installation of Docker Compose?

#

The Yocto system is known for its high degree of customization and streamlining. To minimize system resource usage as much as possible, Yocto typically only includes the most core components. Therefore, by default, Docker Compose may not be included in the RSB-3720’s Yocto 4.0 system, requiring us to install it manually.

Don’t worry, the installation process is very simple and can be done in just a few steps!

Step-by-Step Tutorial: Installing Docker Compose on RSB-3720

#

Here are the detailed steps to manually install Docker Compose on the Advantech RSB-3720 development board (Yocto 4.0 system, Docker already installed):

Step 1: Download Docker Compose on Your Computer

1. Open your browser and go to the Docker Compose GitHub Releases page: https://github.com/docker/compose/releases
2. In the latest version, find the file named docker-compose-linux-aarch64 and download it to your computer.
3. Copy the downloaded docker-compose-linux-aarch64 file to your USB flash drive.

Step 2: Mount the USB Flash Drive on RSB-3720

1. Connect the USB flash drive containing the docker-compose-linux-aarch64 file to your RSB-3720 development board.
2. Open the terminal interface of the RSB-3720.
3. If the mount point does not exist, create one:

   sudo mkdir -p /mnt/usb
   

4. Mount your USB flash drive. Assuming your USB device is recognized as /dev/sda (you may need to use lsblk or dmesg to confirm the actual device name):

   sudo mount /dev/sda /mnt/usb
   

   If your USB device has a different name (e.g., /dev/sdb1), replace /dev/sda with the actual device name in the command.

Step 3: Copy Docker Compose to the Specified Directory

1. Use the cp command to copy the docker-compose-linux-aarch64 file from the USB flash drive to the Docker CLI plugins directory:

   sudo cp /mnt/usb/docker-compose-linux-aarch64 /usr/local/lib/docker/cli-plugins/docker-compose
   

Step 4: Grant Execution Permissions

1. Use the chmod command to add execution permissions to the copied docker-compose file:

   sudo chmod +x /usr/local/lib/docker/cli-plugins/docker-compose
   

Step 5: Test Docker Compose Installation

1. Run the following command in the terminal to verify that Docker Compose has been successfully installed and is working properly:

   docker compose version
   

2. If the installation is successful, you should see the Docker Compose version information output.

Step 6: Unmount the USB Flash Drive

1. After the file is copied, safely unmount your USB flash drive:

   sudo umount /mnt/usb
   

Now, you should be able to use the docker compose command on your RSB-3720 Yocto 4.0 system to manage your multi-container Docker applications!

Important Notes:

• Make sure Docker is properly installed on your RSB-3720 system.
• USB device names may vary depending on the system; please adjust the command according to the actual device name of your system.
• You may need to use the sudo command to perform operations that require root privileges.
