Docker Setup Guide for Ubunto ROS2- Jazzy

This documentation provides a step-by-step guide on how to install Docker locally on a Linux system and use it as a container for Ros2/Jazzy.

---

1. Install Docker on Your Host Machine

To install Docker easily, use the following script:

curl -fsSL get.docker.com -o get-docker.sh
sudo sh get-docker.sh

Run Docker as a Non-Root User

It is recommended to run Docker as a non-root user to prevent your build folder from being owned by root. Execute the following commands in a new terminal:

# Create docker group (may not be required)
sudo groupadd docker

# Add your user to the docker group.
sudo usermod -aG docker $USER

Now log out and log back in before using Docker!!

---

2. Build the Docker Image

The following command builds the Docker image on your host machine. This step is required only once unless you modify the Dockerfile.

git clone https://github.com/alisrour97/Docker_ubunto_24-Ros_jazzy.git
cd Docker_ubunto_24-Ros_jazzy
./build.bash Jazzy

---

3. Run the Docker Container

Before running the docker Copy the create_dc_ros2.sh script inside Ros2-ws. Each time you need to enter the Docker container, execute the following steps:

chmod +x create_dc_ros2.sh
./create_dc_ros2.sh

This starts the Docker container, and its name will be dc_ros2. Just as a note chmod +x is required only once to give permission.

---

4. Managing the Docker Container

If you need to open another instance in a separate terminal, use:

docker exec -u 0 -it dc_ros2 bash

To close the container, simply press Ctrl+D inside the container.

To restart it later, use:

docker start dc_ros2
docker attach dc_ros2

If you want to remove the container:

docker rm dc_ros2

If the ./create_dc_ros2.sh script does not open the container, an old instance may still be running. Remove it using:

docker rm dc_ros2

Then, re-run the script:

./create_dc_ros2.sh
