Unable to get Metricbeat to communicate with Elasticsearch

[stephenb (Stephen Brown)]

Ok so when running separate docker containers each container is its own localhost so referencing localhost in the metricbeat container is not the localhost in the elasticsearch container.

This is docker stuff.

Perhaps 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"]

So when you want one container to communicate/connect with another container you need to use either the IP of the host or use

host.docker.internal
