What is Docker Desktop?
Docker Desktop is a user-friendly interface for running Docker on Windows and Mac OS. It provides a simple way to manage and orchestrate containerized applications. Docker Desktop is designed to make it easy to develop, test, and deploy applications that use containers. It includes a range of features that make it a popular choice for developers and system administrators, including support for Docker Compose, Docker Swarm, and Kubernetes.
With Docker Desktop, users can create and manage containers, images, and volumes. It also provides a range of tools for debugging and troubleshooting containerized applications. Docker Desktop is free to download and use, making it a great option for developers who want to try out containerization without committing to a paid solution.
Key Features of Docker Desktop
Support for Docker Compose
Docker Desktop includes support for Docker Compose, which makes it easy to define and run multi-container applications. With Docker Compose, users can define the services that make up an application in a YAML file, and then use Docker Desktop to build and run the application.
VM Snapshots and Restore Points
Docker Desktop includes a feature called VM snapshots and restore points, which allows users to create snapshots of their virtual machine at specific points in time. This makes it easy to roll back to a previous version of the VM if something goes wrong. VM snapshots and restore points are especially useful for enterprise hosts who need to ensure that their containers are running smoothly and efficiently.
