macedigital/elasticsearch repository overview

⁠Elasticsearch on CentOS

Elasticsearch 2.x on CentOS 7.2 Docker image.

⁠Usage

Running a standalone node is as easy as typing:

docker run -p 9200:9200 -v /host/data/path:/var/lib/elasticsearch macedigital/elasticsearch

The above command exposes the Elasticsearch HTTP interface on port 9200 and uses the host's filesystem to store persistent data.

⁠Configuration

There are a number of runtime environment variables with which you can configure Elasticsearch.

CLUSTER: Set custom cluster name, default is 'elasticsearch'.

CLUSTER_FROM: Migrate data between clusters, ignored if CLUSTER is empty.

NODE_NAME: Set node name, a random name will be chosen if left empty.

MULTICAST: Host(s) for multi-casting. Will install discovery-multicast plugin if set.

UNICAST_HOSTS: Host(s) for unicasting to form a cluster.

PUBLISH_AS: Host+IP setting for using custom transport communication between nodes.

PLUGINS: Comma-separated list of plugins to install on node.

⁠Volumes

/usr/share/elasticsearch/conf:

Override the configuration to you liking by mounting a directory which contains elasticsearch.yml and/or other configuration files.

/var/lib/elasticsearch/data:

Data will be saved in this folder, so you can bind custom volumes for persistence.

⁠Example

The following docker-compose.yml example illustrates how to create a Elaticsearch cluster on the same host:

version: '2'
services:
  master:
    image: macedigital/elasticsearch
    environment:
      - NODE_NAME=es_master
      - PLUGINS=lmenezes/elasticsearch-kopf
    ports:
      - 9200:9200
    container_name: es_master
    volumes:
      - /var/lib/elasticsearch

  node:
    image: macedigital/elasticsearch
    environment:
      - UNICAST_HOSTS=es_master
    links:
      - master
    volumes_from:
      - master
