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. ---

Add `network.host: 0.0.0.0` into `elasticsearch.environment`. If it not works, add `network` information into docker compose. Ref: > > **[Docker Networking](https://www.elastic.co/blog/docker-networking)** > > Learn about Docker networking and how to use it with an Elasticsearch cluster.... ---

> [@Musab\_Dogan](#): > > network.host: 0.0.0.0 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!
