Is your application running in the same container that is running Elasticsearch?

If not, you need to configure the IP address of your application to point to the name of the container that is running Elasticsearch.

Where is this configuration set:

```auto
es = Elasticsearch('http://127.0.0.1:9200/')

```

Is this set in a service that is running in the same container as Elasticsearch?

You need to provide more context about the architecture you are using.

The error you got means that something that is running in the `imageindexerapi` can not connect to Elasticsearch container, if your Elasticsearch container is running and the service is ok, as it seems to be by the health status you shared, then there is something wrong in the configuration of your application running in the `imageindexerapi` or in the way you are starting up docker.
