This article shows you how to install ROS2 and how to use docker environment. The content is concise and easy to understand. It will definitely make your eyes shine. I hope you can gain something from the detailed introduction of this article.

Why Docker?

Docker is a container that can be used to load images. I can package my base environment into a docker image, and everyone can use this image.

During the process of learning ROS, I found that the installation process would encounter many problems. I believe many students were blocked by the problems during installation, so I thought I could make a mirror of ROS for myself and everyone to use. So I chose docker, and found that there is a ready-made mirror directly---easy to start.

After improvement, it can also be packaged into its own mirror image.

Docker installation

1 Update software list

sudo apt-get update

2 Install docker

sudo apt-get install -y docker.io

3 Configuration Boot Start

systemctl start docker systemctl enable docker

4 Test installation successful

sudo docker --version

Pull ROS mirror

I use the foxy version.

1 Download image file, 3 multi-G need to wait a while

sudo docker pull osrf/ros:foxy-desktop

s2 View mirror information

sudo docker images

3 Start mirroring

sudo docker run -it osrf/ros:foxy-desktop

4 enjoy for your Ros

This step shows ROS2 help information, ROS2 has been installed, isn't it fast!!!

ros2 -h

Run ROS Turtle ros2 run turtlesim turtlesim_node

Open a new terminal, restart the image to enter the docker environment

sudo docker run -it osrf/ros:foxy-desktopros2 run turtlesim turtle_teleop_key The above content is about ROS2 installation and docker environment use. Have you learned knowledge or skills?
