VSCodium task to launch container's openvscode-server.
```

:::{caution}
It is easy to confuse to which system a shell is attached!
:::


Below is an example of a shell in VSC running in a container and one *outside*
the container on the host machine. ROS 2 commands will not work in the shell on
your computer!


## Running Commands
In these tutorials there will be text like the following:
:::{div} grouped-block

```console
$ ros2 launch test_pkg test_node
```

Expected output

```console
git version 2.50.0
Docker version 29.5.1, build 123123123
Docker Compose version 5.1.0
Hello from Docker!
...
```
