Note

This is a continuation of a tutorial that starts here

Browse over 100,000 container images from software vendors, open-source projects, and the community. The perfect home for your teams' applications. Push images and make your app accessible to your team or with the Docker Community at large. Create and manage users and grant access to your repositories. Use automated builds and webhooks for easy. The Docker Desktop menu allows you to open the Docker Dashboard, run the Quick Start Guide, configure your Docker settings such as installation, updates, version channels, Docker Hub login, and more. This section explains the configuration options accessible from the Settings dialog.

For the rest of this tutorial, you'll be working with a simple todo list manager that is running in Node.js. If you're not familiar with Node.js, don't worry! No real JavaScript experience is needed!

At this point, your development team is quite small and you're simply building an app to prove out your MVP (minimum viable product). You want to show how it works and what it's capable of doing without needing to think about how it will work for a large team, multiple developers, and so on.

Get the app

Before you can run the application, you need to get the application source code onto your machine. For real projects, you will typically clone the repo. But, for this tutorial, we have created a ZIP file containing the application.

  1. If you're using Windows, make sure that you have Docker for Windows or Docker Community Edition installed on the local machine. See Docker for Windows installation documentation. The install process makes the ZIP file containing the sample available at the localhost address. For Mac, install Docker Desktop for Mac.

  2. Download the source for the app from the Docker repo. You can download the ZIP file for the repo. To download the ZIP file, use the green Code button and choose Download ZIP. Open the ZIP file and Extract All to extract the source of the app from the app folder to a folder on your hard drive.

  3. Once extracted, use your favorite code editor to open the project. If you're in need of an editor, you can use Visual Studio Code. You should see the package.json and two subdirectories (src and spec).

Building the app's container image

In order to build the application, you need to use a Dockerfile. A Dockerfile is simply a text-based script of instructions that is used to create a container image. If you've created Dockerfiles before, you might see a few flaws in the Dockerfile below. But, don't worry! We'll go over them.

  1. Create a file named Dockerfile in the same folder as the file package.json with the following contents.

    Please check that the file Dockerfile has no file extension like .txt. Some editors may append this file extension automatically and this would result in an error in the next step.

  2. If you haven't already done so, open a terminal and go to the app directory with the Dockerfile. Now build the container image using the docker build command.

    Alternatively, you can also right-click on the Dockerfile and choose Build Image... and then specify the tag at the prompt.

    This command used the Dockerfile to build a new container image. You might have noticed that a lot of 'layers' were downloaded. This is because you instructed the builder that you wanted to start from the node:12-alpine image. But, since you didn't have that on your machine, that image needed to be downloaded.

    After the image was downloaded, you copied in your application and used yarn to install your application's dependencies. The CMD directive specifies the default command to run when starting a container from this image.

    Finally, the -t flag tags your image. Think of this simply as a human-readable name for the final image. Since you named the image getting-started, you can refer to that image when you run a container.

    The . at the end of the docker build command tells that Docker should look for the Dockerfile in the current directory.

Starting an app container

Now that you have an image, run the application! To do so, use the docker run command (remember that from earlier?).

  1. Start your container using the docker run command and specify the name of the image you just created:

    Remember the -d and -p flags? You're running the new container in 'detached' mode (in the background) and creating a mapping between the host's port 3000 to the container's port 3000. Without the port mapping, you wouldn't be able to access the application.

  2. After a few seconds, open your web browser to http://localhost:3000.You should see the app!

  3. Go ahead and add an item or two and see that it works as you expect. You can mark items as complete and remove items. Your frontend is successfully storing items in the backend! Pretty quick and easy, huh?

At this point, you should have a running todo list manager with a few items, all built by you! Now, let's make a few changes and learn about managing your containers.

If you take a quick look at the VS Code extension, you should see your two containers running now (this tutorial and your freshly launched app container)!

Recap

In this short section, you learned the very basics about building a container image and created a Dockerfile to do so. Once you built an image, you started the container and saw the running app!

Next, you're going to make a modification to the app and learn how to update the running application with a new image. Along the way, you'll learn a few other useful commands.

Update to the Docker Desktop terms

Professional use of Docker Desktop in large organizations (more than 250 employees or more than $10 million in revenue) requires users to have a paid Docker subscription. While the effective date of these terms is August 31, 2021, there is a grace period until January 31, 2022, for those that require a paid subscription. For more information, see Docker Desktop License Agreement.

Welcome to Docker Desktop for Windows. This page contains information about Docker Desktop for Windows system requirements, download URL, instructions to install and update Docker Desktop for Windows.

Note

Docker only supports Docker Desktop on Windows for those versions of Windows 10 that are still within Microsoft’s servicing timeline.

Containers and images created with Docker Desktop are shared between alluser accounts on machines where it is installed. This is because all Windowsaccounts use the same VM to build and run containers. Note that it is not possible to share containers and images between user accounts when using the Docker Desktop WSL 2 backend.

Nested virtualization scenarios, such as running Docker Desktop on aVMWare or Parallels instance might work, but there are no guarantees. Formore information, see Running Docker Desktop in nested virtualization scenarios.
