My ROS2 Humble docker container.
I use this as my ROS2 environment on my laptop, as well as a devcontainer for vs code.
To be able to use the script from anywhere, symlink it to some folder in your path or ad an alias to your .bashrc or simmilar.
After that you can run ros2-docker to start the container and mount the current working directory to it.
If the container is allready running, ros2-docker will just attache a new shell.
To stop the container run ros2-docker stop.
If you want to build the container localy, change the directory in the ros2-docker.sh file to matche the location on your pc. After that you can run ros2-docker build to build it.
