ROS2, the improved version of ROS (ROS1), is quickly becoming the standard for developing robotics applications.

In this post, we will learn how to release a ROS2 package as a binary file. Binary files are pre-built executables. They are easier to install because they do not require building from the source code. Binary files are perfect if you want to easily distribute a package to other people.

You can easily install them with apt-get install PKG_NAME, or sudo dpkg -i pkg-name.deb, for example.

This is the first post in a series of two posts.

Opening the rosject

In order to release a ROS 2 binary package, we need to have ROS2 installed in our system, and it is also useful to have some simulations. To make your life easier, we already prepared a rosject with a simulation for that:

You can download the rosject on your own computer if you want to work locally, but just by copying the rosject (clicking the link), you will have a setup already prepared for you.

After the rosject has been successfully copied to your own area, you should see a Run button. Just click that button to launch the rosject (below you have a rosject example).

After pressing the Run button, you should have the rosject loaded. Let’s now head to the next section to really get some real practice.


We assume you have a GitHub account. If you don’t have it yet, you can easily create it by following this link:

Creating a ‘release repository’

When a release process runs, it outputs files for instance .md and .yaml files. This output is known as release artifacts. In ROS2, these artifacts need to be stored in a separate repository from the source code files. This repository is what we call the release repository.

So, if your repository name is wall_follower_ros2, you have to create a new repository that you can call, for instance, wall_follower_ros2-release to be used as a release repository for your package.

The ROS2 release process will use that repository to store artifacts as the automated release process runs.

I’m going to create a release repository for
To make your life easier, assuming you may not have a repository with the same name, you can start by forking the repository aforementioned.
After that, please go to and create a repository. The package name can be wall_follower_ros2-release.

You can leave the repository Public, and hit the “Create repository” button.

Creating a release package on GitHub

Creating a release package on GitHub

Start a new release team

release team is a group of users within an organization who has permission to manage all release operations.

If a release team exists in your organization, you can join that team by completing the Update Release Team Membership issue template.

Here, we will assume that no release team exists for our package yet. To request a new release team to be created we must complete the New Release Team issue template.

This form will allow you to create a new release team and add the release repository to your new team in one go.

Below we have an example of the New Release Team issue filled:

After creating the issue, you submit it and wait for the ROS2 team to take it into account.


Installing the tools required on your machine

In order to install the required tools, we need to have a terminal. If you are on The Construct, after having opened a rosject, let’s open a terminal:

Open a new Terminal

Open a new Terminal


Let’s take the chance and also open the Code Editor to be easier to modify our files:

Open the IDE - Code Editor

Open the IDE – Code Editor


Now, let’s go to the terminal and use apt to install bloom together with the python3-catkin-pkg modules.


sudo apt update

sudo apt install python3-bloom python3-catkin-pkg


The package should have been installed with no problems.

Let’s now move to the next step.


Creating a GIT access token to authenticate

Every time you interact with a remote Git repository on the command line (for example, doing a pull, or push operation), you are asked for your GitHub username and password. In this step, we create a Git Access Token to prevent Git from repeatedly prompting for your username and password during the release operation.

You can create an Access Token by clicking the “Generate new token” button in the link below:

When filling out the form, set Note to a descriptive name such as Bloom, set Expiration to No expiration, and select the public_repo and workflow checkboxes.

After clicking on Generate token the page will display a string like CTA2AK1UMAPKSJGSZDR8HWS3GVRAFIQYYETWELT4.

This string is the token, copy it to your clipboard. Make sure to store it safely since you can’t display the token again in the GitHub interface.

In case you need more information on personal access tokens, please follow the link below:

Use the GIT access token to authenticate

Now that we have the Access Token, using the terminal, let’s create a folder named .config:

mkdir -pv ~/.config


Inside that folder, let’s create a file named boom:

cd ~/.config

touch bloom


Using the code editor, insert your GitHub username and PAT into it with the format shown below:

    "github_user": "<your-github-username>", 
    "oauth_token": "<token-you-created-for-bloom>" 


Since hidden files do not appear by default in the Code Editor, you have to click File Open in order to find the .config folder.

Please remember to save your ~/config/boom file by pressing CTRL+S (or File -> Save)


Congratulations. We are halfway through the release of a ROS2 Binary package. We hope this post was really helpful to you. The second post is coming soon. If you want a live version of this post, please check the video in the next section.
