Latest Docker Desktop Version - What is New?

Docker Desktop is a Graphical User Interface (GUI) tool that covers a virtual machine installation. Docker components are unrestricted for Windows, Mac, and Linux, and most Docker containers operate on Linux; Desktop is only open for Windows and Mac. This virtual machine is not required on Linux, as the Docker Engine can execute directly here. Docker Desktop is utilized on Windows and Mac to handle various Docker components and functions, including containers, images, volumes, local Kubernetes, etc. If you're a container creator, using the latest runtime engine version is always advisable. Jack Wallen shows you how to install that most up-to-date Docker version.  

However, the most recent Desktop Docker release is 4.12.0(released June 6, 2021). It may not contain bold new features, but it will undoubtedly include bug fixes and various patches—upgraded kernel to 5.10.124. In specific circumstances, it benefits from installing the latest Docker version. The below article will talk about the overview, features, installation, etc. of the Docker Desktop latest version. Anyone interested in learning Docker will benefit from the Docker online course. This DCA course also is well-suited for freshers, Software developers, Software engineers, Technical leads, System administrators etc. 

Docker Desktop Overview

One of the most reasonable ways to start with Docker is installing Docker Desktop on Mac or Windows. Everyone would wonder, "What is Docker Desktop, and how's it distinguishable from the Docker Engine (open-source)?"   

Docker Desktop version is a GUI on top of Docker Engine and is an easy-to-install application. It includes Docker Engine, Docker CLI client, Docker Compose version, Docker Content Trust, Kubernetes, and Credential Helper. Docker Desktop still utilizes Docker Engine at its core. These tools seamlessly integrate, and interoperability makes Docker Desktop user-friendly—regardless of the experience with Docker.  

Following are the features we get after installing and using Docker Desktop.  

1. Easy to use and install the environment to build, ship, and run your containers. 
2. An effortless way to design and manage using volumes. 
3. Management within Locally or remotely of Docker images. 
4. Collaborating in a better way by sharing repeatable and reproducible development from your local machine to the container. 
5. Straightforward, one-click Kubernetes setup for your local machine. 
6. A dashboard for a quick summary of containers running, images, and volumes. 
7. Support for developing and employing multi-architecture images. 

Docker Desktop adds features atop open-source tooling, allowing it to maintain, monitor easily, and update Docker tooling. Docker Desktop collaborates easily using Docker Dev Environments, authorizing teams to transmit the work with one click via Git or Docker Hub.  

It has an easy-to-use UI with everyday actions: 

1. Starting a container  
2. Pausing and resuming a container  
3. Stopping a container 
4. Establishing a single-node local Kubernetes cluster 
5. Designing or deleting volumes  

GUI and CLI are also always available to you based on your preferences.

Rolling Back to a Previous Version of Docker Desktop

Navigate to docker to find a list of all releases with links to download for Windows, macOS, and various Linux distros. 

Download the release to roll back the installer. It will prompt you to replace the current version of Docker Desktop with the new one; click yes or no to abort the installation. 

Images and volumes that you had previously should still be available after the replacement. 

Unfortunately, this doesn’t always work for all versions or operating systems. For example, it would be necessary to uninstall the existing version and install the new one on Windows. It is a bit more inconvenient than replacing the current version since it is required to rebuild the whole image, but in the end, it does let you roll back to an older version!
