Preparing ZooKeeper and Elasticsearch containers

These procedures are intended for users with Docker knowledge. We do not provide Docker support, just provide guidelines on how to use it with our product. For more information about Docker, see https://docs.docker.com/

Preparing ZooKeeper and Elasticsearch images

Please check the correct component version in the Third-Party Component Compatibility page and edit the ZooKeeper and Elasticsearch versions in the configuration files.

To build ZooKeeper and Elasticsearch images

Create the following file:

zookeeper_elasticsearch/docker-compose.yml

services:
  zookeeper:
    image: zookeeper:3.9.4
    container_name: zookeeper
    mem_limit: 2g
    environment:
      - ZOO_4LW_COMMANDS_WHITELIST=ruok
    healthcheck:
      test: ["CMD-SHELL", "echo ruok | nc localhost 2181 | grep imok"]
      interval: 5s
      timeout: 10s
      retries: 3
    networks:
      - twc-net

    container_name: zoonavigator
    ports:
      - "9000:9000"
    environment:
      - "CONNECTION_MYZK_CONN=zookeeper:2181"
      - "CONNECTION_LOCAL_CONN=localhost:2181"
      - "AUTO_CONNECT_CONNECTION_ID=MYZK"
    depends_on:
      zookeeper:
        condition: service_healthy
    networks:
      - twc-net
