Hello @paakwabenajecteynyarko1,

Thanks for posting in the Isaac ROS forum!

Isaac ROS dev containers are designed with a bind mount at ~/workspaces/isaac_ros-dev/, so anything under that path on the host survives every container restart.
The container image itself, however, is ephemeral, packages you apt install/pip install inside the running container disappear when the container is recreated.
That’s why you’re having to reinstall every time.

Two ways to make it stick:

  1. Clone the repo into src/ and build from source.
    Because src/ and install/ are inside the bind mount, both the source and the built install survive. After the one-time build, you only need to source /workspaces/isaac_ros-dev/install/setup.bash each time you enter the container (which you can put in ~/.bashrc to automate).

  2. docker commit to bake the installed packages into a new image
    It works, but the image grows over time and the changes aren’t version-controlled, and it could be harder to maintain or reproduce on another machine.
