Failed to connect to localhost port 9200: Connection refused

Elastic Stack Elasticsearch
1

Can someone help me? I followed a link on installing elastic,kibana and logstash and i was able to successfully installed elastic. However, when i try to netstat and look for the port 9200, it wasnt there. Also I can't curl the localhost:9200 saying connection refused.

        echo "Waiting for Elasticsearch availability";
        until curl -s http://elasticsearch:9200 | grep -q "missing authentication credentials"; do sleep 30; done;
        echo "Setting kibana_system password";
        until curl -s -X POST -u "elastic:${ELASTIC_PASSWORD}" -H "Content-Type: application/json" http://elasticsearch:9200/_security/user/kibana_system/_password -d "{\"password\":\"${KIBANA_PASSWORD}\"}" | grep -q "^{}"; do sleep 10; done;
        echo "All done!";

Add network.host: 0.0.0.0 into elasticsearch.environment. If it not works, add network information into docker compose.

You're welcome @Edzel_Severino. Which method worked?

We add the network.host: 0.0.0.0 in Elasticsearch environment. However, instead of network.host: 0.0.0.0, what we did is network.host=0.0.0.0
For some reasons, it works.

It's because of the docker-compose syntax.

Thank for your feedback, and happy to hear it worked!
