Is the Docker Playground free to try?

DeployU's Docker Playground provides access to a real container technology environment. A subscription is required for full access. No additional cloud billing or credit card needed.

What can I practice in the Docker Playground?

You can practice Docker Build, Docker Run, Docker Compose, Container Networking, Volumes, Multi-Stage Builds and more in a safe, sandboxed environment.

How long is a Docker Playground session?

Each Docker Playground session lasts 60 minutes and can be extended up to 3 times. Sessions are automatically cleaned up when they end.

Compose Multi-Service Applications , Not Watching

Go beyond single containers. Build full application stacks with Docker Compose: a Node.js API, a PostgreSQL database, a Redis cache, and an Nginx reverse proxy, all wired together. This is how real teams develop and test microservices.
