[BUG] ECONNREFUSED connecting to localhost

• ElasticDump version - 6.82.3 through Docker container
• Elasticsearch version - 6.2.4
• Node.js version (note that nodejs v10+ is required for this tool) - 6.14.15
• Full command you are having issue with (with inputs and outputs):

docker pull elasticdump/elasticsearch-dump

docker \
    run --rm -ti elasticdump/elasticsearch-dump \
    --input=https://prod.com/students \
    --output=http://localhost:9200/students \
    --searchBody="{\"query\": { \"geo_distance\": { \"distance\": \"4mi\", \"geolocation\": {\"lat\": 28.5384, \"lon\": -81.3789 } } } }" \
    --debug \
    --retryAttempts=5 \
    --type data

The above command results in the following error:

But there is a elasticsearch running on localhost:

$ curl http://localhost:9200
{
  "name" : "RDEqfBO",
  "cluster_name" : "elasticsearch",
  "cluster_uuid" : "SfUHE3LyTQKxWj3sxYZSFg",
  "version" : {
    "number" : "6.2.4",
    "build_hash" : "ccec39f",
    "build_date" : "2018-04-12T20:37:28.497551Z",
    "build_snapshot" : false,
    "lucene_version" : "7.2.1",
    "minimum_wire_compatibility_version" : "5.6.0",
    "minimum_index_compatibility_version" : "5.0.0"
  },
  "tagline" : "You Know, for Search"
}

When curl can connect to local ES, so should elasticdump.

Thanks for the note, i’ll update the docs. 👍🏾

That was it! Thanks @ferronrsmith

For future reference, --output had to be changed to use host’s DNS name. Like so:

--output=http://host.docker.internal:9200/students
