When we do the integration testing, the system get up and down, and we found that kafka seems have to start after zookeeper.
We have to run the following script to workaround it.
docker stop dockerfiles_dmaap_1
docker stop dockerfiles_kafka_1
docker stop dockerfiles_zookeeper_1
docker start dockerfiles_zookeeper_1
docker start dockerfiles_kafka_1
docker start dockerfiles_dmaap_1
