Thus, as long as you have a GitHub repo with a project and a `Dockerfile`, you can complete this part of the tutorial.
## Enable access to Docker Hub
The [Docker Hub](https://hub.docker.com/) is a hosted repository service provided by Docker for finding and sharing container images.
Before we can publish our Docker image to Docker Hub, we must grant GitHub Actions access to Docker Hub API.
To set up the access to Docker Hub API:
1. Create a new Personal Access Token (PAT) for Docker Hub.
* Go to the [Docker Hub Account Settings](https://hub.docker.com/settings/security) and then click **New Access Token**.
* Let's call this token `docker-gs-ping-ci`. Input the name and click **Create**.
* Copy the token value, we'll need it in a second.
2. Add your Docker ID and PAT as secrets to your GitHub repo.
* Navigate to your GitHub repository and click **Settings** > **Secrets** > **New secret**.
* Create a new secret with the name `DOCKER_HUB_USERNAME` and your Docker ID as value.
* Create a new secret with the name `DOCKER_HUB_ACCESS_TOKEN` and use the token value from the step (1).
Your GitHub repository **Secrets** section would look like the following.
![GitHub Secrets](../../ci-cd/images/github-secrets.png){:width="500px"}
Now it will be possible to refer to these two variables from our workflows. This will open up an opportunity to publish our image to Docker Hub.
## Set up the CI workflow
In the previous section, we created a PAT and added it to GitHub to ensure we can access Docker Hub from any GitHub Actions workflow. But before setting out to build the images for releasing our software, let's build a CI pipeline to run the tests first.

Now, let’s create a GitHub Actions workflow to build and store the image for our application in Docker Hub. We can achieve this by creating two Docker actions:
