docker-compose up -d

If you're on MacOS set an environment variable like:

export DOCKER_KAFKA_HOST=$(ipconfig getifaddr en0)

that is afterwards used in docker-compose.yml to identify the KAFKA_ADVERTISED_HOST_NAME. Some similar workaround has to exist for Windows users. For linux I assume you can just set it to localhost if you're only running on Kafka node. See github.com/wurstmeister/kafka-docker/wiki/Connectivity.
