This is a toy example of using docker-compose to run a classic ROS master, talker and listener nodes in separate containers, yet linked together via a common project network. For the host to simply connect to the containers while maintaining transparent domain resolution to preserve the methodology of ROS's messaging networkwe'll include a service in the compose file named "resolvable" that serves as a Docker DNS resolver for the host.
With in this directory foo that should contain just the files from this giststart the example by running:. You'll see the ROS nodes come online and wait for roscore to spin up. Then you'll begin to watch the simple exchange of the talker and listener through the output printed to the screen from each container.
You should see docker-compose form an output like so:. Now with the project launched by compose, we can ping each container from the host using its domain name by default, the name of the service in this case. Now on the host, we should also be able to query the master about topics, and once more, even subscribe to messages directly from nodes inside the containers! Ok, lets play around with this example as see what all the parts do. We'll resume by stopping our example and cleaning the containers from the project:.
Restart the project again via docker-compose upand in a new terminal on the host, take a look and the network by inspecting the project network. Notice the default bridge driver is engaged here, and the all our project services can be found under this network.
ROS 2 CI with GitHub Actions
Above you'll notice that the Gateway is set to You can see this by running ifconfig on the host and finding the interface with the same hash id as the project network. To check this we can try out a simple netcat example by listening with the container and transmitting from the host:. Notice the echo's subscription never comes through, yet is registered just fine under the subscriber list.
So, even if the two can reach each other, it doesn't yet seem enough to receive subscribed ros topics. Specifying a custom IPAM config for the project's default network setting each services IP would be a slight improvement, yet still rigid and possibly conflicting with other networks.
Now lets switch back to what was previously working. Lets try the same thing that failed above, but now with our little host-level DNS gateway for docker running on the same project network. Yes, now we have what we wanted.
This is all made easy again thanks to the running gateway container. In fact, if we opened a second fresh terminal, leaving the one on the host above still echoing, we'll see our single host machine subscribed using two different URIs. Resolvable is providing a DNS entry for the Docker bridge interface address, by default for docker0but really the br-5f5df3fb in this case. This is used to communicate with services with a known port bound to the Docker bridge. What we've seen here is how we need to remain mindful while specifying ROS variables with respect to facilities of the network between the nodes and host.
As a recommendation, using a DNS entry for the Docker bridge interface perhaps the more flexible and simpler approach than using IP address.

A common example would be a test runner that is attached to source control. This runner can be scripted to intake new commits, proposed merges, etc. Other examples might include scripts that output packages or executables whenever a new release is tagged, or upload documentation to a web host whenever markdown or html files are touched.
Source code hosting providers like GitHub and GitLab offer tools to define these workflows and run them on your code for free with limitations, of course.
Other solutions include the external service Travis-CI formerly the de-facto solution for GitHub and the self hosted automation suite Jenkins. While a workflow can be defined line by line with a large shell script, actions can automate large chunks of script.
A GitHub action for running a specific linter for instance, ESLint would handle installing and invoking the linter, while an action for uploading files to an S3 bucket would take arguments for destination url and keys and handle authenticating and uploading the target. A number of actions are being maintained by the tooling working group specifically for working with ROS packages.
The action-ros-ci-template repository contains a minimal example of running a number of linters across the codebase. However, If you want to ensure code style is enforced and users are aware of the formatting requirements, we recommend instead implementing explicit tests for the linters. That way, other contributors are explicitly notified of your code style conventions, and will be able acquire the linters with rosdep.
In your package, create a directory named. In it, create a workflow. Paste the following into it:.
Triggers to run this workflow. Here we state that any commit in a pull request, as well as any commit pushed to master will trigger this workflow. Block containing all the discrete jobs to run. Each job starts in a fresh container, and can only receive data from other jobs through artifacts. We define a single job, build-and-testand set low-level configuration options for it.
In this case, we want to run the test on the mainline supported operating systems, so we define a matrix, which means the job will run for each permutation of values in the matrix. In addition, we set fail-fast to false, so a failure on one platform does not cancel the others. We now enter the steps of the workflow itself, beginning with invoking the setup-ros2 action. We create a step, give it a name, and for its contents simply state that it uses the action in question, at a fixed version 0.
We use the with block to pass arguments to the setup-ros action, specifying that it should setup ROS 2 Eloquent only. This step is the meat of our pipeline — the action-ros-ci action will collect our package no need to use the checkout actiongrab any dependencies, setup a workspace, and build and test our package.

This will include teaching on how to design threat models for robotics, hardening the ROS ecosystem through SROS2 as well as using several penetration testing tools to verify that the robot is no longer vulnerable to those attacks.
Starting with the edition, ROSCon has a pre-conference workshops half-day, this workshop will thus take place on the afternoon of October 30th. Industry 4. When analyzed from a security point of view, the global picture is disheartening: robotics industry has not seriously allocated effort to follow good security practices in the robots produced. Instead, most manufacturers keep forwarding the problem to the end-users of these machines. As learned in previous technological revolutions, such as at the dawn of PCs or smartphones, action needs to be taken in time to avoid disastrous consequences.
In an attempt to provide the robotics and security communities with the right tools to perform assessments, in this paper we present aztarna, a footprinting tool for robotics. We discuss how such tool can facilitate the process of identifying vestiges of different robots, while maintaining an extensible structure aimed for future fingerprinting extensions. With this contribution, we aim to raise awareness and interest of the robotics community, robot manufacturers and robot end-users on the need of starting global actions to embrace security.
We open source the tool and disclose preliminary results that demonstrate the current insecurity landscape in industry. We argue that the robotic ecosystem is in need of generating a robot security community, conscious about good practices and empowered by the right tools.

Examples Turtlebot3 Session: github. External Links ROS2 github.Sometimes tutorials refer to ros2 demos and sometimes to ros2 examples and both are actively used. Eventually the demos may get refactored to some where else or just dropped entirely, but for now they are safe to study and use as examples.
They are kept up-to-date and are tested regularly. As much as possible they're meant to be "copy-paste-edit"-able, as a starting point for various tasks. And to that end they are built but not extensively tested as that would be invasive to the examples or their cmake code and are light on explanatory comments.
In contrast to the examples they will be highly commented and have comprehensive automated tests like the demosas we'll be referencing their code in stylized documentation again like the ROS 1 tutorial I linked to again. Also these tutorials will likely show one good way to do things, where as the examples have lots of different styles demonstrated, e.
