Docker Desktop is an easy-to-install application for your Mac, Windows or Linux environment that enables you to build and share containerized applications and microservices. Docker Desktop includes the Docker daemon (dockerd), the Docker client (docker), Docker Compose, Docker Content Trust, Kubernetes, and Credential helper
Docker Desktop is a comprehensive GUI-based application designed to bridge the gap between non-Linux operating systems (Windows and macOS) and the Linux-native container world.
On Windows: It primarily uses WSL 2 (Windows Subsystem for Linux), which offers near-native performance by sharing resources with the host.
On macOS: It uses a custom hypervisor (Apple Hypervisor framework) to run a slim Linux kernel.
Networking & Filesystem: Docker Desktop includes proprietary 'proxy' logic to map your local localhost:3000 to the container's port inside the VM, and to sync your local source code into the container (via virtiofs or gRPC FUSE) with minimal latency.
Docker Dashboard: A GUI to manage containers, images, and volumes without touching the CLI.
Kubernetes: A single-node K8s cluster that you can toggle on/off with one click—perfect for testing your local microservices.
Docker Scout: Integrated security that automatically scans your images for vulnerabilities (CVEs) as you build them.
Docker Extensions: A marketplace that lets you plug in tools like Snyk, Aqua Security, or Disk Usage viewers directly into the dashboard.
Docker Build Cloud: (New for 2025/2026) Allows you to offload heavy container builds to AWS/cloud servers to save your local CPU/RAM.
