MySQL Connector cannot connect to Elasticsearch Docker Instance

[stephenb (Stephen Brown)]

Are these 2 separate containers? if so localhost to connect to each other... will not work as 1 container's localhost is separate from the other container's localhost

Perhaps take a look at

Filebeat Docker - Elasticsearch Host Issue

Hi @mwsprotte Welcome to the community! Docker Networking Issue not Elastic... Another explanation Might be worth reading... if you are new to docker try using host.docker.internal docker run \ --net=elastic docker.elastic.co/beats/filebeat:7.17.4 \ setup -E setup.kibana.host=host.docker.internal:5601 \ -E output.elasticsearch.hosts=["https://host.docker.internal:9200"]

in short, you will probably need to use host.docker.internal between the two containers
