I'm trying to run Elasticsearch on an docker swarm. It works as a single node cluster for now, but only when the transport.host=localhost setting is included. Here is main part of docker-compose.yml:
version: "3"
services:
elasticsearch:
image: "elasticsearch:7.4.1" #(base version)
hostname: elasticsearch
ports:
- "9200:9200"
environment:
- cluster.name=elasticsearch
- bootstrap.memory_lock=true
- ES_JAVA_OPTS=-Xms512m -Xmx512m
- transport.host=localhost
volumes:
- "./elasticsearch/volumes:/usr/share/elasticsearch/data"
networks:
- logger_net
volumes:
logging:
networks:
logger_net:
external: true
Above configuration results in the yellow cluster state (because some indexes require additional replica).
Elasticsearch status page is unavailable when I'm using IP of the elasticsearch docker container in a transport.host setting or without a transport.host=localhost setting.
I think that using a transport.host=localhost setting is wrong. Is proper configuration of Elasticsearch in docker swarm available?
