Connection to ElasticSearch running inside Docker fails (MacOS) #3708
Description
I am running lbry-sdk integration tests locally on MacOS, with elastic-search inside Docker. I used the lbry-sdk/Makefile command to launch it:
elastic-docker:
docker run -d -v lbryhub:/usr/share/elasticsearch/data -p 9200:9200 -p 9300:9300 -e"ES_JAVA_OPTS=-Xms512m -Xmx512m" -e "discovery.type=single-node" docker.elastic.co/elasticsearch/elasticsearch:7.12.1
In order to connect herald -> elastic-search, I had to disable the SetSniff() option.

Making a --nosniff option MAY NOT be the best solution here. I found the following comment describes how to fix this using the network.publish_host option of ElasticSearch. olivere/elastic#824 (comment)
Example:
docker run --env network.publish_host=127.0.0.1 ...
I tested "--env network.publish_host=127.0.0.1" and it worked for me.
Symbolic addresses like network.publish_host=_local_ are supported.
