Setup a new Workspace

This use-case describes how to setup a new ROS workspace using scripts from the ROS Team Workspace (RosTeamWS) framework. Besides the creation of a local workspace, creation of a Ubuntu-based docker container is supported. For more details have a look below in the Docker workspace section.

Local workspace

The setup-ros-workspace command creates a new workspace in the current folder. If you supply a path relative to your home directory, the workspace is created there.

Usage of the script for setting up a new ROS workspace.

setup-ros-workspace WS_FOLDER ROS_DISTRO

All parameters are optional but they are positional. If you want to omit any of the input parameters use "-" as argument. The script creates a new ROS workspace with name <WS_FOLDER> in <CURRENT_WORKING_DIRECTORY>/<WS_FOLDER>. However if you pass a folder name relative to your $HOME directory, like for example: setup-ros-workspace ~/<WS_FOLDER> ROS_DISTRO, then a new workspace is created inside $HOME/<WS_FOLDER>. The passed ROS distribution <ROS_DISTRO> is sourced as base if no other workspace is sourced. After the workspace has been created, you have to open a new terminal and can then type the new created alias _<WS_FOLDER>. This is going to source the new workspace and you can then switch to its root|source|install|build folders by executing respectively rosd|rosds|rosdi|rosdb.

Example:

Example usage of the script for setting up a new ROS workspace.

setup-ros-workspace subfolder/my_new_workspace rolling

Creates in the current folder a subfolder subfolder and then creates a new workspace called my_new_workspace. Opening a new terminal and executing _my_new_workspace is going to source this workspace.

Default value for <WS_FOLDER> is “workspace”.

Docker workspace

How to setup a workspace inside a docker container.

setup-ros-workspace-docker WS_FOLDER ROS_DISTRO

Like the setup-ros-workspace script, the setup-ros-workspace-docker script creates a new local ROS workspace. Then a Ubuntu docker container is built and the new created workspace is mounted inside the docker container under the same directory as in the host. The first time a docker container is built can take quite a while. When the first build is finished you are directly connected as user inside the container. You can verify this by checking if your hostname has changed. To exit a container simply type the exit command.

Reconnect to a container

If you exited a container and want to reconnect as a user, you have to run the rtw_switch_to_docker command. However before executing this, you have to source your workspace with the alias _<WS_FOLDER>. If you want to connect as a root user, you can execute rtw_switch_to_docker_root.

Recreate a container

If you removed an image, you can recreate it by switching into the .rtw_docker_defines folder inside your workspace and then executing the ./recreate_docker.sh command. After the process is finished you should be able to normally start, reconnect and stop the container.

CLI overview

Overview of the cli
command	description
`setup-ros-workspace-docker`	Creates a new workspace and maps the workspace inside a docker container. You can then switch to docker using `rtw_switch_to_docker`.
`rtw_switch_to_docker`	Starts the docker container if it has been stopped and connects to the container as user.
`rtw_switch_to_docker_root`	Starts the docker container if it has been stopped and connects to the container as root-user.
`rtw_stop_docker`	Stops the docker container.
