You must have a [GitHub](https://github.com/signup) account and a [Docker](https://hub.docker.com/signup) account to complete this section. ## Overview In this section, you'll learn how to set up and use GitHub Actions to build and test your Docker image as well as push it to Docker Hub. You will complete the following steps: 1. Create a new repository on GitHub. 2. Define the GitHub Actions workflow. 3. Run the workflow. ## Step one: Create the repository Create a GitHub repository, configure the Docker Hub credentials, and push your source code. 1. [Create a new repository](https://github.com/new) on GitHub. 2. Open the repository **Settings**, and go to **Secrets and variables** > **Actions**. 3. Create a new **Repository variable** named `DOCKER_USERNAME` and your Docker ID as a value. 4. Create a new [Personal Access Token (PAT)](/manuals/security/for-developers/access-tokens.md#create-an-access-token) for Docker Hub. You can name this token `docker-tutorial`. Make sure access permissions include Read and Write. 5. Add the PAT as a **Repository secret** in your GitHub repository, with the name `DOCKERHUB_TOKEN`. 6. In your local repository on your machine, run the following command to change the origin to the repository you just created. Make sure you change `your-username` to your GitHub username and `your-repository` to the name of the repository you created. ```console $ git remote set-url origin https://github.com/your-username/your-repository.git ``` 7. Run the following commands to stage, commit, and push your local repository to GitHub. ```console $ git add -A $ git commit -m "my commit" $ git push -u origin main ``` ## Step two: Set up the workflow Set up your GitHub Actions workflow for building, testing, and pushing the image to Docker Hub. 1. Go to your repository on GitHub and then select the **Actions** tab.

This section guides you through configuring CI/CD for a C++ application using GitHub Actions. It covers creating a GitHub repository, defining a workflow to build, test, and push Docker images to Docker Hub, and setting up necessary credentials and secrets.
