Initializing Docker Assets, Running the Application, and Summary

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/docker/docker-dotnet-sample ``` ## Initialize Docker assets Now that you have an application, you can use `docker init` to create the necessary Docker assets to containerize your application. Inside the `docker-dotnet-sample` directory, run the `docker init` command in a terminal. `docker init` provides some default configuration, but you'll need to answer a few questions about your application. Refer to the following example to answer the prompts from `docker init` and use the same answers for your prompts. ```console $ docker init Welcome to the Docker Init CLI! This utility will walk you through creating the following files with sensible defaults for your project: - .dockerignore - Dockerfile - compose.yaml - README.Docker.md Let's get started! ? What application platform does your project use? ASP.NET Core ? What's the name of your solution's main project? myWebApp ? What version of .NET do you want to use? 8.0 ? What local port do you want to use to access your server? 8080 ``` You should now have the following contents in your `docker-dotnet-sample` directory. ```text ├── docker-dotnet-sample/ │ ├── .git/ │ ├── src/ │ ├── .dockerignore │ ├── compose.yaml │ ├── Dockerfile │ ├── README.Docker.md │ └── README.md ``` To learn more about the files that `docker init` added, see the following: - [Dockerfile](/reference/dockerfile.md) - [.dockerignore](/reference/dockerfile.md#dockerignore-file) - [compose.yaml](/reference/compose-file/_index.md) ## Run the application Inside the `docker-dotnet-sample` directory, run the following command in a terminal. ```console $ docker compose up --build ``` Open a browser and view the application at [http://localhost:8080](http://localhost:8080). You should see a simple web application. 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 `docker-dotnet-sample` 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). You should see a simple web application. 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 .NET application using Docker. Related information: - [Dockerfile reference](/reference/dockerfile.md) - [.dockerignore file reference](/reference/dockerfile.md#dockerignore-file) - [Docker Compose overview](/manuals/compose/_index.md) ## Next steps In the next section, you'll learn how you can develop your application using Docker containers.

After cloning the repository, the guide instructs users to use the `docker init` command to create the necessary Docker assets for containerizing the application. It shows an example of the prompts and expected answers during the initialization process. After initialization, the guide explains how to run the application using `docker compose up --build` and how to access it in a web browser. Additionally, it covers running the application in the background using the `-d` option and stopping it with `docker compose down`. The section concludes with a summary of the containerization process and provides related Docker documentation links.
