Full Description

Docker Swarm support for elasticsearch

Automatically configures elasticsearch to connect other nodes inside docker swarm cluster.

Affects elasticsearch parameters:

  • - an IP address of the container
  • network.publish_host - an IP address of the container
  • - a list of IP addresses other nodes inside docker swarm service

In order to run docker swarm service from this image it is REQUIRED to set environment variable SERVICE_NAME to the name of service in docker swarm.
Please avoid to manually configure parameters listed above.


docker network create --driver overlay --subnet \
  --opt encrypted elastic_cluster

docker service create --name elasticsearch --network=elastic_cluster \
  --replicas 3 \
  --env SERVICE_NAME=elasticsearch \
  --publish 9200:9200

Since elasticsearch requires vm.max_map_count to be at least 262144 but docker service create does not support sysctl management you have to set
vm.max_map_count on all your nodes to proper value BEFORE starting service.
On Linux Ubuntu: sysctl -w "vm.max_map_count=262144". Or echo "vm.max_map_count=262144" >> /etc/sysctl.conf to set it permanently.

To access elasticsearch cluster connect to any docker swarm node to port 9200 using default credentials: curl

To change default elasticsearch parameters use environment variables. See for more details.
