Running Dekaf

If you have an existing Apache Pulsar instance, you can run Dekaf by using this command:

docker run \
  -it \
  -e DEKAF_PULSAR_BROKER_URL="pulsar://0.0.0.0:6650" \
  -e DEKAF_PULSAR_WEB_URL="http://0.0.0.0:8085" \
  -p 8090:8090 \
  tealtools/dekaf:latest

This command will run Dekaf Free edition connected to your Apache Pulsar instance.

Configuration

You can configure Dekaf by mounting the YAML configuration file to the /dekaf/config.yaml path.

Configuring application using environment variable is also supported.

See the Configuration Reference page for more details.

Data Directory

Dekaf allows users to create reusable objects like pre-configured filters and consumer sessions. These objects are stored in the directory specified by the dataDir configuration property.

That means that in production setup you should persist this directory data to make it available after the Dekaf container restart.
