The preferred choice for millions of developers that are building containerized apps. Docker Desktop is an application for MacOS and Windows machines for the building and sharing of containerized applications. Access Docker Desktop and follow the guided onboarding to build your first containerized application in minutes.

- Docker Desktop is the easiest way to get started with either Swarm or Kubernetes. A swarm is a group of machines that are running Docker and joined into a cluster. After that has happened, you continue to run the Docker commands you’re used to, but now they are executed on a cluster by a swarm manager.
- Newer Windows systems meet the requirements for Docker Desktop for Windows and do not need VirtualBox. Step 7: Update the application Because the application code is now mounted into the container using a volume, you can make changes to its code and see the changes instantly, without having to rebuild the image.
Development frameworks, platforms, and tools that do not offer a rich development experience will ultimately lack in adoption. Docker is an amazing technology but, what is the development experience like? Not too long ago, I wrote about creating and debugging an ASP.NET Core Docker container in two different ways.
- Visual Studio 2017 (Windows)
- Visual Studio Code (Linux)
With the launching of Visual Studio 2019 recently, I felt compelled to target one more IDE 🙂 .
Prerequisites
The first step is making sure Visual Studio is set up correctly. This is a simple as installing Visual Studio 2019 with the .NET Core cross-platform development workload installed. More specifically, if you select Individual Components, you need to ensure that the Container Development Tools component is selected as shown below.

Creating an ASP.NET Core Docker Container
As explained in this blog post, the new project dialog in Visual Studio has been given an overhaul. I have become quite accustomed to the previous version however, I must admit the improvements are very intuitive. For this tutorial, we will select the ASP.NET Core Web Application template and click Next.
Once this is done, we can give our new project a name, location, and solution name. As you can see, this process is much more like a wizard as opposed to the monolithic dialog that was used in previous versions.
Now we can provide some more specifics for our new application. For the purposes of this example we will select the API project template. That said, a key piece can be found in the advanced section. Here we want to select Enable Docker Support and make sure Linux is selected in the following drop-down.
Similar to when working with Visual Studio 2017, a Dockerfile is generated with four named build stages (base, build, publish, and final). Multistage builds are helpful to optimize layers and keep our Dockerfile easy to maintain.

Next lets take a look at how our application gets built and deployed as a container.
Building The Container
Prior to building or debugging our application, we will already notice some activity in the Container Tools output in the output window.
This is a new optimization added to Visual Studio 2019. In order to allow our application to build, deploy, and run quickly Visual Studio preemptively creates a container. We can see the container by running docker ps from the command line.
With the http and https ports exposed, the container is primed and ready to go. If we open a browser and browse to the http port, 49558 in my case, we see that we do not get a response yet. This makes sense because while our container is started, nothing is actually deployed to it yet.

To build and deploy our application to the running container, we must debug using the Docker configuration profile. This should be selected by default. Once we are up and running, we can see that our application is available through http/https ports that were exposed in our Docker container.
We can also see that the same container that was started when we created our application is still running. When we run our application a new container isn’t created, rather the output from our project is copied into the running container. We can see this by observing the running containers which shows or original container is still running.
Visual Studio remotely attaches to the process running inside the container. This gives us the ability to set breakpoints and debug our application while it is running.
The development experience in Visual Studio 2019 is very similar to Visual Studio 2017 as it pertains to building Docker containers. That said, there are some nice enhancements under the hood that make the development process even more seemless. It is great to Microsoft’s continued investment in this great new technology!

Step 2: Customize and Push to Docker Hub
The last step used a Docker image which Microsoft publishes and maintains. Next step, create your own custom image. You should have a Docker ID, you probably created it to download Docker Desktop.
In your favorite text editor create a file called Dockerfile in the same C:temp directory. No extension, just Dockerfile. Paste in this code and save the file:
This tells Docker to use the same IIS base image, and create a layer that adds in the HTML you created in the last step. Instead of manually copying a file into the container, you will create an image with your HTML already inside it. To build the image, in your terminal, type:

Two things, first replace <YourDockerID> with your Docker ID. Also notice the “.” at the end of the line. That tells Docker to build in the context of this directory. So when it looks to COPY the file to /inetpub/wwwroot it will use the file from this directory.
You can run it:
And go to http://localhost:8081 to see the page - note your original container is still running and you can see it at http://localhost:8080.
Finally push to Docker Hub:

You may be asked to login if you haven’t already. Then you can go to hub.docker.com, login and check your repositories

Finally, stop and remove the running containers:
