Hey there, Is it possible to set environment variables using docker-compose on Elasticsearch 2.4.4? I am trying to set cluster-name with classic method ```auto environment: - cluster-name=test ``` but the cluster is ignoring it. I tried also to set the ES\_JAVA\_HEAP and it seems to be only appended to executed command. This method is is obviously working with ES 6.x or ES 7.x. I am not understanding if there is any limit on ES 2.4 usage. ---

2.4 is very well past [EOL](https://www.elastic.co/support/eol) and is no longer supported. Is there a reason you are using it? ---

Oh yes, I mean is there any limit regards the docker-compose usage for that ES version. ---

Yes, I am trying to migrate (ES mechanism not ES data ) to a newer version so I need to do some tests ---

Is it possible to find all the variables that could be usable? ---

Hi @rschirin Really I think you are just going to need to plow through the docs and download the distribution, frankly we don't focus on releases that old. A quick look at the `elasticsearch.yml` ... looks like there is only about 15 settings total... > **[Configuration | Elasticsearch Guide \[2.4\] | Elastic](https://www.elastic.co/guide/en/elasticsearch/reference/2.4/setup-configuration.html)** ---
