Installation by Docker

Apache IoTDB' Docker image is released on https://hub.docker.com/r/apache/iotdbopen in new window
Add environments of docker to update the configurations of Apache IoTDB.

Have a try

# get IoTDB official image
docker pull apache/iotdb:1.3.0-standalone
# create docker bridge network
docker network create --driver=bridge --subnet=172.18.0.0/16 --gateway=172.18.0.1 iotdb
# create docker container
docker run -d --name iotdb-service \
              --hostname iotdb-service \
              --network iotdb \
              --ip 172.18.0.6 \
              -p 6667:6667 \

              -e dn_rpc_port=6667 \
              apache/iotdb:1.3.0-standalone              
# execute SQL
docker exec -ti iotdb-service /iotdb/sbin/start-cli.sh -h iotdb-service

External access:

# <IP Address/hostname> is the real IP or domain address rather than the one in docker network, could be 127.0.0.1 within the computer.
$IOTDB_HOME/sbin/start-cli.sh -h <IP Address/hostname> -p 6667

Notice:The confignode service would fail when restarting this container if the IP Adress of the container has been changed.

# docker-compose-standalone.yml
version: "3"
services:
  iotdb-service:
    image: apache/iotdb:1.3.0-standalone
    hostname: iotdb-service
    container_name: iotdb-service
    ports:
      - "6667:6667"
    environment:
      - cn_internal_address=iotdb-service
      - cn_internal_port=10710
      - cn_consensus_port=10720
      - cn_seed_config_node=iotdb-service:10710

      - dn_internal_address=iotdb-service
      - dn_rpc_port=6667

networks:

    external: true

If you'd like to limit the memory of IoTDB, follow these steps:

  1. Add another configuration of volumes: ./iotdb-conf:/iotdb/conf and then start the IoTDB docker container. Thus, there are some configuration files in directory of iotdb-conf.
  2. Change the memory configurations in confignode-env.shopen in new window and datanode-env.shopen in new window of iotdb-conf, and then restart the IoTDB docker container again.

deploy cluster

Until now, we support host and overlay networks but haven't supported bridge networks on multiple computers.
Overlay networks see 1C2Dopen in new window and here are the configurations and operation steps to start an IoTDB cluster with docker using host networks。

Suppose that there are three computers of iotdb-1, iotdb-2 and iotdb-3. We called them nodes.
Here is the docker-compose file of iotdb-2, as the sample:

version: "3"
services:
  iotdb-confignode:
    image: apache/iotdb:1.3.0-confignode
    container_name: iotdb-confignode
    environment:
      - cn_internal_address=iotdb-2
      - cn_seed_config_node=iotdb-1:10710
      - cn_internal_port=10710
      - cn_consensus_port=10720
      - schema_replication_factor=3
      - schema_region_consensus_protocol_class=org.apache.iotdb.consensus.ratis.RatisConsensus
      - config_node_consensus_protocol_class=org.apache.iotdb.consensus.ratis.RatisConsensus
      - data_replication_factor=3
      - data_region_consensus_protocol_class=org.apache.iotdb.consensus.iot.IoTConsensus
    volumes:
      - /etc/hosts:/etc/hosts:ro
      - ./data/confignode:/iotdb/data
      - ./logs/confignode:/iotdb/logs
    network_mode: "host"

  iotdb-datanode:
    image: apache/iotdb:1.3.0-datanode
    container_name: iotdb-datanode
    environment:
      - dn_rpc_address=iotdb-2
      - dn_internal_address=iotdb-2
      - dn_seed_config_node=iotdb-1:10710
      - data_replication_factor=3
      - dn_rpc_port=6667
      - dn_mpp_data_exchange_port=10740
      - dn_schema_region_consensus_port=10750
      - dn_data_region_consensus_port=10760
      - data_region_consensus_protocol_class=org.apache.iotdb.consensus.iot.IoTConsensus
       - schema_replication_factor=3
      - schema_region_consensus_protocol_class=org.apache.iotdb.consensus.ratis.RatisConsensus
      - config_node_consensus_protocol_class=org.apache.iotdb.consensus.ratis.RatisConsensus
    volumes:
      - /etc/hosts:/etc/hosts:ro
      - ./data/datanode:/iotdb/data/
      - ./logs/datanode:/iotdb/logs/
    network_mode: "host"

Notice:

  1. The cn_seed_config_node and dn_seed_config_node of three nodes must the same and they are the first starting node of iotdb-1 with the cn_internal_port of 10710。
  2. In this docker-compose file,iotdb-2 should be replace with the real IP or hostname of each node to generate docker compose files in the other nodes.
  3. The services would talk with each other, so they need map the /etc/hosts file or add the extra_hosts to the docker compose file.
  4. We must start the IoTDB services of iotdb-1 first at the first time of starting.
  5. Stop and remove all the IoTDB services and clean up the data and logs directories of the 3 nodes,then start the cluster again.
