ROS1 autocomplete for interactive container not working

[jmehami1]

Hi, I have been running ROS1 containers on two different computers with OSs Ubuntu 22.04 and Ubuntu 20.04 to avoid local installations. I start the containers interactively using the following command on both systems:
docker run -it --rm --network host osrf/ros:noetic-desktop-full

I'm assuming the script ros_entrypoint.sh sources the setup.bash file when container is started. I try to type and autocomplete ROS commands. For example, when I type "ros" and press TAB I find all the relevant ROS commands.

The issue appears when finding subcommands. For example, If I want to run the rosbag command and I want to see its subcommands, they do not appear when I press TAB and instead directories are shown as follows:

In order to fix this I have to source the setup.bash script as follows:
source /opt/ros/noetic/setup.bash
After sourcing the setup.bash script, I can now see the subcommands when autocompleting with TAB as follows:

Why do I have to source the setup.bash script after the ros_entrypoint.sh has already carried out the command.

The ros_entrypoint.sh is as follows:

Looks like some catkin environment hooks dont carry over to the new shell.

The environment does but it must work differently for the autocompletion stuff from rosbash 🤷

I appreciate the fast response. I guess I will just keep sourcing setup.bash script each time I start up a ROS container. I'll set up a keybinding to automate it.

The setup is sources by the Dockerfile entrypoint, so that sets the ENV, but like @mikaelarguedas hypothesizes, perhaps something shell specific is not carrying over to the bash process you start via docker run that the entrypoint would then exec?

docker run -it --rm osrf/ros:noetic-desktop-full bash

Perhaps you could add the source setup to the bashrc of the desired user you want to start the container from? E.g.

docker run -it --rm --user root osrf/ros:noetic-desktop-full echo 'source /opt/ros/$ROS_DISTRO/setup.bash' >> ~/.bashrc && bash

Hi,
Thanks for the recommendation. I have fixed the issue as follows:

docker run -it --rm --network host ros:noetic-ros-core bash -c "echo 'source /opt/ros/noetic/setup.bash' >> ~/.bashrc && source ~/.bashrc && bash"

Both rosbag and rostopic are autocompleting for subcommands. You will have to manually add the ros version (noetic) to the path, you can't use "$ROS_DISTRO" because it doesn't exist on your PC.
