elasticsearch-jupiter

A Elasticsearch 2.x run in Docker

Build image

./build.sh -t 2.4.5-1

Configs

Since it will change the ulimit, fs_max and max_map_count, the image must be run in privileged mode, e.g.

docker run --privileged=true elasticsearch2:2.4.5-1

Supported ENV variables as configs

Name	Default	Description
CLUSTER_NAME	elasticsearch-jupiter	The ES cluster name
ES_HEAP_SIZE	512m	The heap memory size of the node
HTTP_ENABLE	true	True if the node will expose REST API port - 9200
NODE_DATA	true	True if the node will run in data mode
NODE_MASTER	true	True if the node will run in master mode
ZEN_HOSTS	""	The comma separated list of IP addresses of ES cluster nodes, e.g. `"172.27.2.20","172.27.2.21","172.27.2.22","172.27.2.23"`
NUMBER_OF_MASTERS	1	The minimum number of master nodes
NUMBER_OF_REPLICAS	0	The number of replicas of the index
NUMBER_OF_SHARDS	1	The number of shards of the index

Note:

Both master and data mode can be true, that means this node is master and data node,
Both master and data mode can be false, that means this node is only for clients with REST API, a.k.a. client mode,
If HTTP is disabled, it cannot be connected using REST API

Example

This example run 4 nodes in the same VM, with

1 node for master only
2 nodes for master and data
1 node for data only
Heap size as 1Gi each

Because we want set the IP address of the docker instance, we use a customized Docker network.

docker network create --driver=bridge --subnet=172.27.2.0/24 --ip-range=172.27.2.0/24 --gateway=172.27.2.1 esnet

Run the 1 node for master only

chmod 777 /opt/es/d0
docker run --name=es-master --privileged=true -d \
           -e ES_HEAP_SIZE=1g -e NODE_DATA=false \
           -e ZEN_HOSTS="172.27.2.20","172.27.2.21","172.27.2.22","172.27.2.23" \
           --network esnet --ip 172.27.2.20 \
           -v /opt/es/d0:/data \
           elasticsearch2:2.4.5-1

Run the 2 nodes for master and data

chmod 777 /opt/es/d1
docker run --privileged=true -d
           -e ES_HEAP_SIZE=1g \
           -e ZEN_HOSTS="172.27.2.20","172.27.2.21","172.27.2.22","172.27.2.23" \
           --network esnet --ip 172.27.2.21 \
           -v /opt/es/d1:/data \
           elasticsearch2:2.4.5-1

chmod 777 /opt/es/d2
docker run --privileged=true -d \
           -e ES_HEAP_SIZE=1g \
           -e ZEN_HOSTS="172.27.2.20","172.27.2.21","172.27.2.22","172.27.2.23" \
           --network esnet --ip 172.27.2.22 \
           -v /opt/es/d2:/data \
           elasticsearch2:2.4.5-1

Run the 1 node for data only

chmod 777 /opt/es/d3
docker run --name=es-data --privileged=true -d \
           -e ES_HEAP_SIZE=1g \
           -e NODE_MASTER=false \
           -e HTTP_ENABLE=false \
           -e ZEN_HOSTS="172.27.2.20","172.27.2.21","172.27.2.22","172.27.2.23" \
           --network esnet --ip 172.27.2.23 \
           -v /opt/es/d3:/data \
           elasticsearch2:2.4.5-1
