• Please make sure that you have Docker
• Open your terminal
• Create a new directory: mkdir dekaf && cd ./dekaf
• Download the docker-compose.yaml file and start it:

wget https://raw.githubusercontent.com/tealtools/dekaf/main/docker-compose.yaml
docker compose pull && docker compose up

• Open http://localhost:8090
• Wait until Pulsar is ready
• Enjoy ☕️

We also run a demo application that produces data for two new tenants in this quick start.

If you don't see the demo-schema-types and demo-shop tenants in the tenant list, try to wait for a few seconds and reload the page.

If you want to disable the demo application, remove it from the docker-compose.yaml file.

• If the pulsar container cannot start, we recommend ensuring that you have 6GB or more Docker memory limit. We'll adjust the docker-compose memory for a lower limit later.
• In case, you observe bookie-related errors from the pulsar container, the simplest way to fix it is to remove the corresponding Docker volume. In case you need the volume data, make a backup first. Otherwise follow these steps:
  • Stop containers by running docker compose down
  • Run docker volume ls | grep pulsar-data to find the proper <volume_name>
  • Run docker volume rm <volume_name> to delete the volume
  • Restart containers by running docker-compose up
