Advanced Configuration with WSL 2
Docker Desktop leverages Windows Subsystem for Linux 2 (WSL 2) to provide seamless container development experience. WSL 2 offers enhanced performance and full system call compatibility for Linux containers.
Sample Container Deployment
## Pull Ubuntu image
docker pull ubuntu:latest
## Run interactive container
docker run -it ubuntu:latest /bin/bash
## Inside container, perform operations
apt-get update
apt-get install nginx
Docker Desktop provides integrated tools for monitoring container performance, resource allocation, and system-level insights, enabling developers to optimize their container development workflow efficiently.
