+> **Acknowledgment**
+>
+> Docker would like to thank [Pradumna Saraf](https://twitter.com/pradumna_saraf) for his contribution to this guide.
+
+* Containerize and run a Bun application using Docker
+* Set up a local environment to develop a Bun application using containers
+* Configure a CI/CD pipeline for a containerized Bun application using GitHub Actions
+* Deploy your containerized application locally to Kubernetes to test and debug your deployment
+
+After completing the Bun getting started modules, you should be able to containerize your own C++ application based on the examples and instructions provided in this guide.
+
+Start by containerizing an existing Bun application.

+description: Learn how to configure CI/CD using GitHub Actions for your Bun application.
+---
+
+## Prerequisites
+
+Complete all the previous sections of this guide, starting with [Containerize a Bun application](containerize.md). 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 value.
+
+4. Create a new [Personal Access Token (PAT)](../../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.
+
+2. Select **set up a workflow yourself**.
+
+   This takes you to a page for creating a new GitHub actions workflow file in
+   your repository, under `.github/workflows/main.yml` by default.
+
+3. In the editor window, copy and paste the following YAML configuration and commit the changes.
+
+   ```yaml
+   name: ci
+   
+   on:
+     push:
+       branches:
+         - main
+   
+   jobs:
+     build:
+       runs-on: ubuntu-latest
+       steps:
+         -
+           name: Login to Docker Hub
+           uses: docker/login-action@v3
+           with:
+             username: ${{ vars.DOCKER_USERNAME }}
+             password: ${{ secrets.DOCKERHUB_TOKEN }}
+         -
+           name: Set up Docker Buildx
+           uses: docker/setup-buildx-action@v3
+         -
+           name: Build and push
+           uses: docker/build-push-action@v6
+           with:
+             platforms: linux/amd64,linux/arm64
+             push: true
+             tags: ${{ vars.DOCKER_USERNAME }}/${{ github.event.repository.name }}:latest
+   ```
+
+   For more information about the YAML syntax for `docker/build-push-action`,
+   refer to the [GitHub Action README](https://github.com/docker/build-push-action/blob/master/README.md).
+
+## Step three: Run the workflow
+
+Save the workflow file and run the job.
+
+1. Select **Commit changes...** and push the changes to the `main` branch.
+
+   After pushing the commit, the workflow starts automatically.
+
+2. Go to the **Actions** tab. It displays the workflow.
+
+   Selecting the workflow shows you the breakdown of all the steps.
+
+3. When the workflow is complete, go to your
+   [repositories on Docker Hub](https://hub.docker.com/repositories).
+
+   If you see the new repository in that list, it means the GitHub Actions
+   successfully pushed the image to Docker Hub.
+
+## Summary
+
+In this section, you learned how to set up a GitHub Actions workflow for your Bun application.
+
+Related information:
+ - [Introduction to GitHub Actions](../../build/ci/github-actions/_index.md)
+ - [Workflow syntax for GitHub Actions](https://docs.github.com/en/actions/using-workflows/workflow-syntax-for-github-actions)
+
+## Next steps
+
+Next, learn how you can locally test and debug your workloads on Kubernetes before deploying.

+
+## Prerequisites
+
+* You have a [Git client](https://git-scm.com/downloads). The examples in this section use a command-line based Git client, but you can use any client.
+
+## Overview
+
+This section walks you through containerizing and running a Bun application.
+
+## Get the sample application
+
+Clone the sample application to use with this guide. Open a terminal, change directory to a directory that you want to work in, and run the following command to clone the repository:
+
+```console
+$ git clone https://github.com/PradumnaSaraf/bun-docker.git
+```
+
+You should now have the following contents in your `bun-docker`
+directory.
+
+```text
+├── bun-docker/
+│ ├── compose.yml
+│ ├── Dockerfile
+│ ├── LICENSE
+│ ├── server.js
+│ └── README.md
+
+```
+
+To learn more about the files in the repository, see the following:
+ - [Dockerfile](../../reference/dockerfile.md)
+ - [.dockerignore](../../reference/dockerfile.md#dockerignore-file)
+ - [compose.yml](/reference/compose-file/_index.md)
+
+## Run the application
+
+Inside the `bun-docker` directory, run the following command in a
+terminal.
+
+```console
+$ docker compose up --build
+```
+
+Open a browser and view the application at [http://localhost:3000](http://localhost:3000). You will see a message `{"Status" : "OK"}` in the browser.
+
+In the terminal, press `ctrl`+`c` to stop the application.
+
+### Run the application in the background
+
+You can run the application detached from the terminal by adding the `-d`
+option. Inside the `bun-docker` directory, run the following command
+in a terminal.
+
+```console
+$ docker compose up --build -d
+```
+
+Open a browser and view the application at [http://localhost:8080](http://localhost:8080).
+
+
+In the terminal, run the following command to stop the application.
+
+```console
+$ docker compose down
+```
+
+For more information about Compose commands, see the [Compose CLI
+reference](/reference/cli/docker/compose/_index.md).
+
+## Summary
+
+In this section, you learned how you can containerize and run your Bun
+application using Docker.
