this is more a statement than an issue. If you are like me not having always time to sit for hours in front of the course. It could happen that you loose all the images when you log off !
The last section takes two hours and it could happen for sure.
To ease life I have created that little script
start=$(date +%M%s) docker pull osrf/ros:noetic-desktop-full docker pull osrf/ros:humble-desktop docker build -f dockerfile_nvidia_ros -t nvidia_ros . docker build -f dockerfile_nvidia_ros2 -t nvidia_ros2 . docker build -f dockerfile_tb3 -t turtlebot3_base . docker build -f dockerfile_tb3_overlay -t turtlebot3_overlay . end=$(date +%M%s) echo "Done Elapsed Time: $(($end-$start)) seconds"
but be aware it can take up to 40 minutes to recreate all images so not sure if that helps
At the construct
It would be great if docker containers could persist as of the above
