How to create an Ubuntu docker image and container with Arena SDK

This knowledge base article will describe how to create a docker image and docker container within Ubuntu 22.04 that can run LUCID’s Arena SDK.

Install Docker Engine on Ubuntu

Before you install Docker Engine for the first time on a new host machine, you need to set up the Docker repository. Afterward, you can install and update Docker from the repository.

Set up the repository:

1. Update the apt package index and install packages to allow apt to use a repository over HTTPS:

$ sudo apt-get update

$ sudo apt-get install \
    ca-certificates \
    curl \
    gnupg \
    lsb-release

2. Add Docker’s official GPG key:

$ sudo mkdir -p /etc/apt/keyrings
$ curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo gpg --dearmor -o /etc/apt/keyrings/docker.gpg

3. Use the following command to set up the repository:

$ echo \
  "deb [arch=$(dpkg --print-architecture) signed-by=/etc/apt/keyrings/docker.gpg] https://download.docker.com/linux/ubuntu \
  $(lsb_release -cs) stable" | sudo tee /etc/apt/sources.list.d/docker.list > /dev/null

Install Docker Engine:

1. Update the apt package index:

$ sudo apt-get update

Install Docker Engine, containerd, and Docker Compose.

2. To install the latest version, run:

$ sudo apt-get install docker-ce docker-ce-cli containerd.io docker-compose-plugin

3. Verify that the Docker Engine installation is successful by running the hello-world image:

$ sudo docker run hello-world

This command downloads a test image and runs it in a container. When the container runs, it prints a confirmation message and exits.

 

You have now successfully installed and started Docker Engine. The docker user group exists but contains no users, which is why you’re required to use sudo to run Docker commands. Continue to Linux post-install to allow non-privileged users to run Docker commands and for other optional configuration steps.

 

Get the Dockerfile, Install Docker image and run the Docker Container:

Download the complete Docker container directory and all associated files in this zip file. This file also contains the Python wheel ( 2.7.1) and Areana SDK (v0.1.95).

Here is the directory structure:

/Docker

── docker-compose.yml   

├── Dockerfile

├── README.md 

 ├── resources 

 │   ├── arena_api  << This directory contains the Python wheel.

│   └── ArenaSDK << This directory contains the Arena SDK.  

├── ros2_arena_setup.sh   

├── ros2_ws   

│   ├── arena_api-2.0.0-py3-none-any.whl   

│   ├── build 

│   ├── install

 │   ├── log   

│   ├── ros2_ws_and_software.code-workspace

│   ├── src   

│   └── usefull_cmnds.txt 

└── _VERSION_PY_

 

After copying the SDK and .whl file to the directory folders open up the terminal:

$ cd back to arena_camera_ros2-master/

$ sudo docker build -f Dockerfile -t osrf/ros:eloquent-desktop-lucid-camera-v.1.0 .

$ sudo docker images

Next, list all the docker images built –

$ sudo docker run -it --network host osrf/ros:eloquent-desktop-lucid-camera-v.1.0 .

The docker container will open.

Head to the compiled examples folder in ArenaSDK_Linux_x64 and run Cpp_Acquisition.cpp

Optionally, we can create a MACVLAN network  which assigns a MAC address to the docker container and bridges it to the physical network on the host system.

To create a MacVLan network:

$ sudo docker network create -d macvlan --subnet 169.254.0.0/16 --gateway 169.254.0.1 --ip-range 169.254.0.253/32 -o parent=enp2s0 custommacvlan
