A First Look at Docker Desktop Enterprise

Delivered as part of Docker Enterprise 3.0, Docker Desktop Enterprise is a new developer tool that extends the Docker Enterprise Platform to developers’ desktops, improving developer productivity while accelerating time-to-market for new applications.

It is the only enterprise-ready Desktop platform that enables IT organizations to automate the delivery of legacy and modern applications using an agile operating model with integrated security. With work performed locally, developers can leverage a rapid feedback loop before pushing code or docker images to shared servers / continuous integration infrastructure.

\Imagine you are a developer & your organization has a production-ready environment running Docker Enterprise. To ensure that you don’t use any APIs or incompatible features that will break when you push an application to production, you would like to be certain your working environment exactly matches what’s running in Docker Enterprise production systems. This is where Docker Enterprise 3.0 and Docker Desktop Enterprise come in. It is basically a cohesive extension of the Docker Enterprise container platform that runs right on developers’ systems. Developers code and test locally using the same tools they use today and Docker Desktop Enterprise helps to quickly iterate and then produce a containerized service that is ready for their production Docker Enterprise clusters.

The Enterprise-Ready Solution for Dev & Ops

Docker Desktop Enterprise is a perfect devbed for enterprise developers. It allows developers to select from their favourite frameworks, languages, and IDEs. Because of those options, it can also help organizations target every platform. So basically, your organization can provide application templates that include production-approved application configurations, and developers can take those templates and quickly replicate them right from their desktop and begin coding. With the Docker Desktop Enterprise graphical user interface (GUI), developers are no longer required to know lower-level Docker commands and can auto-generate Docker artifacts.

Let us talk about the various features of Docker Desktop Enterprise 2.0 which is discussed below:

  • Version selection: Configurable version packs ensure the local instance of Docker Desktop Enterprise is a precise copy of the production environment where applications are deployed, and developers can switch between versions of Docker and Kubernetes with a single click.
    • Docker and Kubernetes versions match UCP cluster versions.
    • Administrator command line tool simplifies version pack installation.
  • Application Designer: Application Designer provides a library of application and service templates to help developers quickly create new container-based applications. Application templates allow you to choose a technology stack and focus on the business logic and code, and require only minimal Docker syntax knowledge.
    • Template support includes .NET, Java Spring, and more.
    • Single service and multi-services applications are supported.
    • Deployable to Kubernetes or Swarm orchestrators
    • Supports Docker App format for multi-environment, parameterized application deployments and application bundling
  • Device management:
    • The Docker Desktop Enterprise installer is available as standard MSI (Win) and PKG (Mac) downloads, which allows administrators to script an installation across many developer workstations.
  • Administrative control:
    • IT organizations can specify and lock configuration parameters for creation of a standardized development environment, including disabling drive sharing and limiting version pack installations. Developers can then run commands using the command line without worrying about configuration settings.

Under this blog post, we will look at two of the promising features of Docker Desktop Enterprise 2.0:

  • Application Designer 
  • Version packs
Installing Docker Desktop Enterprise

Docker Desktop Enterprise is available both for Microsoft Windows and MacOS. One can download via the below links:

The above installer includes:

E8065780 09f6 4429 af90 9c21f4229979

If you want to use a different version of the Docker Engine and Kubernetes for development work install version pack Enterprise 2.0, you can download version pack Enterprise 2.0 via this link.

Version packs are installed manually or, for administrators, by using the command line tool. Once installed, version packs can be selected for use in the Docker Desktop Enterprise menu.

Installing Additional Version Packs

When you install Docker Desktop Enterprise, the tool is installed under C:\Program Files\Docker\Desktop location. Version packs can be installed by double-clicking a .ddvp file. Ensure that Docker Desktop is stopped before installing a version pack. The easiest way to add Version Pack is through CLI running the below command:

Open up Windows Powershell via “Run as Administrator” and run the below command:

dockerdesktop-admin.exe’ -InstallVersionPack=’C:\Program Files


Uninstalling Version Packs

Uninstalling Version Pack is a matter of single-line command as shown below:

dockerdesktop-admin.exe’ -UninstallVersionPack <VersionPack>

In my next blog post, I will show you how to leverage Application Designer tool to build custom application.
