This is a curated list of demos that showcase Apache Kafka® stream processing on the Confluent Platform. Some demos run on local Confluent Platform installs (download Confluent Platform) and others run on Docker (install Docker and Docker Compose).
The best demo to start with is cp-demo, which spins up a Kafka event streaming application using KSQL for stream processing.
cp-demo also comes with a playbook and video series, and is a great configuration reference for Confluent Platform.

For local installs:
- Confluent Platform 5.2
- Env var
CONFLUENT_HOME=/path/to/confluentplatform - Env var
PATHincludes$CONFLUENT_HOME/bin - Each demo has its own set of prerequisites as well, documented in each demo's README
For Docker:
- Docker version 17.06.1-ce
- Docker Compose version 1.14.0 with Docker Compose file format 2.1
As a next step, you may want to launch just the services in Confluent Platform with no pre-configured connectors, data sources, topics, schemas, etc. Then you can manually configure any connectors or applications that you want to use.
We have several resources for this purpose:
- cp-all-in-one: this Docker Compose file launches all services in Confluent Platform, and runs them in containers in your local host.
- cp-all-in-one-cloud: use this with your pre-configured Confluent Cloud instance. This Docker Compose file launches all services in Confluent Platform (except for the Kafka brokers), runs them in containers in your local host, and automatically configures them to connect to Confluent Cloud.
- Confluent CLI: for local, non-Docker installs of Confluent Platform. This CLI launches all services in Confluent Platform, and runs them on your local host.
- Generate test data: Hello world for launching Confluent Platform, plus different ways to generate more interesting test data for your topics
