🐳 kafka-docker-playground

✨ Fully automated Apache Kafka® and Confluent® Docker (and CFK) based examples

👷‍♂️ Easily build examples or reproduction models

🍿 See it in action

More clips (run menu, topics, logs, source code, repro model, benchmark, Claude Code, analyze...) on the website, and 2–3 minute narrated walkthroughs, from the symptom to the HTML report, in the 🎬 Bite size sessions.

📚 Documentation

Check out kafka-docker-playground.io to learn how to use the playground, how it works and how to build your own reproduction models !

✨ Features

• 🔗 170+ onprem (or self-managed) connectors examples
• 🌤️ 100+ fully-managed connectors examples
• 🔐 10+ secured environments (SASL, RBAC, SSL...)
• ☁️ Confluent Cloud examples
• 💸 Confluent commercial features (Tiered Storage, Control Center, Audit logs...)
• ♻️ Cluster Linking, Replicator and MirrorMaker 2 examples
• 🎯 Run examples with any Confluent Platform or connector versions
• 🧠 Easily run commands with playground CLI
• 📈 Benchmark a connector: throughput, version comparison, and where the time of the tasks goes (Java Flight Recorder)
• 📊 Find what is wrong with shareable reports: thread dumps, GC logs, flight recordings, network captures, connector benchmarks, SMT tests, Oracle XStream and CFK diagnostics
• 🎬 Learn with bite size sessions: short narrated videos, each about one thing the playground does for you, with the commands to copy
• 🍪 Master a family of commands with the deep dives: mental model, what runs under the hood, gotchas, a hands-on lab replayed nightly by CI, and recipes for support repros
• 🤖 Use it with Claude Code: project guide, skills to add examples, review PRs, change the CLI or analyze Oracle XStream reports
• 🎓 Learn how the playground works
• 🧰 Build your own examples or reproduction models with the reproduction toolkit
• ✨ Work remotely with VS Code using playground ec2 CLI command
• 🦭 Run examples with Podman through its Docker-compatible API
• 🤖 Automated testing using Github Actions CI
• ☸️ Run any onprem connector example using Confluent For Kubernetes (CFK) completely transparently using --environment cfk CLI option
• 👾 And even more playgrounds...

🏁 Getting Started

Check out the How to Use section, then select an example in the Content section and run it !

💡 Ideology

Most of the examples in the playground are very basic, but it allows to quickly test components in an automated way (and with any versions) and most importantly to easily build your own reproduction models !
