hikhvar/docker-elasticsearch

Dockerfile for a base Elasticsearch image to be extended by others (allow to install plug-ins, change configuration, etc.)

docker-elasticsearch

Very lean (120MB) and highly configurable Elasticsearch Docker image.

Current software

• OpenJDK 8u112
• Elasticsearch 5.2.2

Run

Attention

• In order for bootstrap.mlockall to work, ulimit must be allowed to run in the container. Run with --privileged to enable this.
• Multicast discovery is no longer built-in

Ready to use node for cluster elasticsearch-default:

docker run --name elasticsearch \
	--detach \
	--privileged \
	--volume /path/to/data_folder:/data \
        quay.io/pires/docker-elasticsearch:5.2.2

Ready to use node for cluster myclustername:

docker run --name elasticsearch \
	--detach \
	--privileged \
	--volume /path/to/data_folder:/data \
	-e CLUSTER_NAME=myclustername \
        quay.io/pires/docker-elasticsearch:5.2.2

Ready to use node for cluster elasticsearch-default, with 8GB heap allocated to Elasticsearch:

docker run --name elasticsearch \
	--detach \
	--privileged \
	--volume /path/to/data_folder:/data \
	-e ES_JAVA_OPTS="-Xms8g -Xmx8g" \
        quay.io/pires/docker-elasticsearch:5.2.2

Master-only node for cluster elasticsearch-default:

docker run --name elasticsearch \
	--detach \
	--privileged \
	--volume /path/to/data_folder:/data \
	-e NODE_DATA=false \
	-e HTTP_ENABLE=false \
        quay.io/pires/docker-elasticsearch:5.2.2

Data-only node for cluster elasticsearch-default:

docker run --name elasticsearch \
	--detach --volume /path/to/data_folder:/data \
	--privileged \
	-e NODE_MASTER=false \
	-e HTTP_ENABLE=false \
        quay.io/pires/docker-elasticsearch:5.2.2

Client-only node for cluster elasticsearch-default:

docker run --name elasticsearch \
	--detach \
	--privileged \
	--volume /path/to/data_folder:/data \
	-e NODE_MASTER=false \
	-e NODE_DATA=false \
        quay.io/pires/docker-elasticsearch:5.2.2

I also make available special images and instructions for AWS EC2 and Kubernetes.
