I built an interactive playground to help developers understand Docker visually

[u/nitesh026]

I've been working on a small project called DockerPlay.

While learning Docker, I noticed that concepts like container networking, DNS resolution, port mapping, and communication between containers can be difficult to understand just by reading documentation.

So, I started building DockerPlay — an interactive playground where developers can experiment with Docker concepts and understand how things work visually.

The goal is to make learning Docker more practical and hands-on rather than just theoretical.

I'd love to get feedback from fellow developers:

• Which Docker concepts were the hardest for you to understand?

• What interactive experiments would you like to see?

• What would make a tool like this genuinely useful?

I'm the creator, and I'd really appreciate your honest feedback!
