May be you can run with

```auto
bin/elasticsearch -Enetwork.host=${DOCKER_IP}

```

Or something like this?

But here I think ${DOCKER\_IP} is not resolved to anything...  
It supposed to be an ENV VAR: [https://www.elastic.co/guide/en/elasticsearch/reference/current/settings.html#\_environment\_variable\_substitution](https://www.elastic.co/guide/en/elasticsearch/reference/current/settings.html#_environment_variable_substitution)
