Running a GUI
Allow host system to use X Display Server
Open your host terminal and run the following command: (The plus sign is optional)
xhost +local:podman
Using Docker
If you are running docker, change podman to docker in the corresponding command:
xhost +local:docker
Connect container display to current host display
For Non-NVIDIA users
If you don't have NVIDIA graphics card installed or NVIDIA graphics is not required in container, then you can use the following command:
podman run --security-opt=label=disable -v /tmp/.X11-unix:/tmp/.X11-unix -e DISPLAY=$DISPLAY -d --name <name> -i <image>
In the following command, -e DISPLAY=$DISPLAY syncs your environment variable DISPLAY from host system to container.
podman run -v /tmp/.X11-unix:/tmp/.X11-unix -e DISPLAY=$DISPLAY --security-opt=label=disable --hooks-dir=/usr/share/containers/oci/hooks.d/ -d --name <name> -i <image>
--hooks-dir
The --hooks-dir in the following command is related to NVIDIA Installation.
For example, if there exists a image tagged ros:latest on your system, the command would be:
podman run -v /tmp/.X11-unix:/tmp/.X11-unix -e DISPLAY=$DISPLAY --security-opt=label=disable --hooks-dir=/usr/share/containers/oci/hooks.d/ -v $PWD/ROS:/home/ROS:Z -d --name ros2 -i ros:latest
Aliasing
If you want to alias any word to automate this process, you can add the following line to your ~/.bashrc file: (For example, for ros2)
alias ros2="(xhost +local:podman) && (podman exec -it ros2 /bin/bash)"
For remaining steps, you can follow Container documentation.
