What is Tranqulity?

From the Tranquility Github page:

Tranquility helps you send real-time event streams to Druid and handles partitioning, replication, service discovery, and schema rollover, seamlessly and without downtime.

How to use?

This is best used as part of a docker-compose.yml file with Druid also being created. By default, the container launches the Tranquility server with no pre-loaded configs, but you can also provide a config file by mounting one and specifying its location via the TRANQUILITY_CONFIG_FILE environment variable.

So assuming you have a config file located at conf/tranquility/config.json in your local working directory and a full druid stack + zookeeper running on your local machine (or in containers w/ exposed ports), you could spin up tranquility with the following:

docker run -it \
  --network host \
  -v `pwd`/conf/tranquility:/etc/tranquility \
  -e TRANQUILITY_CONFIG_FILE=/etc/tranquility/config.json \
  -e TRANQUILITY_ZOOKEEPER_CONNECT=localhost:2181 \
  -p 8200:8200 \

Alternately, you could add this as a service in a docker-compose file as follows:

version: "2"
services:
  zookeeper:
    image: confluentinc/cp-zookeeper:latest
    environment:
      ZOOKEEPER_CLIENT_PORT: 2181
      ZOOKEEPER_TICK_TIME: 2000
    ports:
      - 2181:2181
  tranquility:
    image: rusnyder/tranquility:latest
    volumes:
      - ./conf/tranquility:/etc/tranquility
    environment:
      TRANQUILITY_CONFIG_FILE: /etc/tranquility/config.json
      TRANQUILITY_PROPERTIES_ZOOKEEPER_CONNECT: zookeeper:2181
    ports:
      - 8200:8200
