Summary
Play with Docker (PWD) is a free, browser-based Docker playground created by Marcos Liljedhal and Jonathan Leibiusky, sponsored by Docker Inc. It provides an Alpine Linux VM in-browser where users can run Docker commands, build and run containers, and create Docker Swarm clusters, all backed by Docker-in-Docker (DinD).
Play with Docker（PWD）是由 Marcos Liljedhal 和 Jonathan Leibiusky 創建、Docker Inc 贊助的免費瀏覽器 Docker 遊樂場。它在瀏覽器中提供 Alpine Linux 虛擬機，用戶可以運行 Docker 命令、構建和運行容器，以及創建 Docker Swarm 集群，底層使用 Docker-in-Docker（DinD）實現。
Key Points
- Browser-based Docker playground: no local install required, ready in seconds
- Provides free Alpine Linux VMs in-browser using Docker-in-Docker (DinD) technology
- Supports Docker Swarm Mode: can simulate multi-node cluster topologies
- Companion training site at training.play-with-docker.com with labs and quizzes from beginner to advanced
- Great for quickly testing Docker commands, exploring container networking, and practicing cluster operations
Insights
PWD lowers the barrier to Docker experimentation to near zero — it removes the “install and configure first” friction that stops beginners. DinD is the enabling technology: by running Docker inside Docker, the platform can simulate multiple nodes without requiring physical or cloud VMs. For learners, the integrated training site adds structured progression that a raw terminal alone doesn’t provide.

Raw Excerpt
PWD is a Docker playground which allows users to run Docker commands in a matter of seconds. It gives the experience of having a free Alpine Linux Virtual Machine in browser, where you can build and run Docker containers and even create clusters in Docker Swarm Mode.
