Step 2: Docker Account Setup
Step 2: Docker Account Setup#
Duckietown leverages containerization to ensure software portability and reproducibility.
Most procedures entail the use of
docker operations behind the scene.
That is why we need to set up the logins for docker within
We use DockerHub to distribute the containerized version
of its software modules, and most Duckietown procedures entail some
docker operations behind the scenes.
If you are unfamiliar with Docker, we strongly recommend reading the following reference page to gain a working understanding of this tool: The Duckietown Intro to Docker
1) Create a DockerHub account#
If you do not have one already, you can sign up for a DockerHub account at this link.
2) Log in to Docker#
Once you have an account on DockerHub and an access token, you can test them by logging in using the command,
docker login -u DOCKER_USERNAME
DOCKER_USERNAME is the username you chose when signing up on DockerHub.
You will then be prompted for your password, paste the access token we created earlier and press
3) Configure shell#
We are now going to provide the same username and access token to the shell in order to automate most of the back-end operations involving docker.
These credentials are only stored locally;
Never use your account password instead of an access token;
You can pass wour DockerHub credentials to the Duckietown Shell by running the following command,
dts config docker credentials set \
--username DOCKERHUB_USERNAME \
With an extra positional argument, one could specify a custom docker registry server other than
dts config docker set --help for more details.
Before we move on, let us make sure you have set our credentials correctly.
Never skip a checkpoint!
If you have trouble with any of these commands, see the FAQs section below.
If your Docker login was successful, you should be able to run
dts config docker credentials info
You should see an output similar to the following,
. registry: docker.io
. username: DOCKERHUB_USERNAME
. secret: DOCKERHUB_ACCESS_TOKEN
If you continue past a test that did not work, you will have further software issues down the line, and they will be more complex to fix. Instead, if you do not get the expected outcome at any checkpoint:
First check the troubleshooting guide below.

I mistakenly set a wrong/unwanted username or password. How can I update the credentials?
Just run the command again with the correct credentials. Only the latest inputs are stored for the same docker registry.
I would like to remove my stored docker credentials. How could I achieve that?
Simply use a text editor to remove the section
