#elasticsearch

Dockerfile to create an elasticsearch instance that can be configured via environment variables. All these settings will default to the initial values from the elasticsearch.yml configuration file if you don't specify anything.

Currently available elasticsearch settings are as follows.

• es.cluster.name
• es.node.master
• es.index.number_of_shards
• es.index.number_of_replicas
• es.transport.tcp.port
• es.http.port
• es.discovery.zen.minimum_master_nodes
• es.discovery.zen.ping.multicast.enabled

Installation

From docker index

A pre-built image is available from the docker index. You can pull this with the following command:

docker pull sliebau/elasticsearch

From github

If you want to build the image yourself, clone this repository and run the following command:

docker build -t *name of your choice* .

Usage

You can override the elasticsearch settings mentioned above by passing them as environment variables to docker when you create the container.

To start an elasticsearch container with default settings:

docker run -d -p 9200:9200 -p 9300:9300 sliebau/elasticearch:latest

To override specific settings you would use the --env option. To name your cluster testcluster the command would look like:

docker run -d -p 9200:9200 -p 9300:9300 --env es.cluster.name=testcluster sliebau/elasticearch:latest
