Go ES client https://godoc.org/gopkg.in/olivere/elastic.v6 throws the "no active connection found: no Elasticsearch node available" error when attempting to connect from OS X host to ES running in docker container. There's many discussions on how to solve it in v5.*, however, I couldn't find anything for v6.4.
Docker-compose part:
elasticsearch:
image: elasticsearch:6.4.2
network_mode: "bridge"
expose:
- "9200"
- "9300"
volumes:
- ./es-data:/usr/share/elasticsearch/data
ports:
- "9200:9200"
- "9300:9300"
Go client call:
esClient, esClientErr :=
elastic.NewClient(elastic.SetURL("http://127.0.0.1:9200"))
if esClientErr != nil {
return nil, fmt.Errorf("Failed to connect to ES: %v", esClientErr)
}
Output:
2018/11/09 15:57:54 Failed to connect to ES: no active connection found: no Elasticsearch node available
exit status 1
UPDATE
Setting network.publish_host: "_local_"
solved the problem. The publish_address
is set to 127.0.0.1:9300
now.
