We are running logstash within a Docker Container to monitor RabbitMQ. Due to some huge messages we have to increase the memory with which logstash is operating.

According to [https://www.elastic.co/guide/en/logstash/current/config-setting-files.html](https://www.elastic.co/guide/en/logstash/current/config-setting-files.html) we can do this via changing properties within the file jvm.options. In our situation (we provision our machines with Ansible) this has the drawback that we are delivering a lot of other properties with this file - and maybe loose some changes in this file in the future due to it doesn't get updates on increasing logstash versions.

On searching for an environment setting I found LS\_HEAP\_SIZE =\> which sounds promising. But in [https://www.elastic.co/guide/en/logstash/current/docker.html](https://www.elastic.co/guide/en/logstash/current/docker.html) it looks the "official" way seems to be the one with the config files.

So the question is: Is the environment property LS\_HEAP\_SIZE an "official" way of increasing logstash memory in this deployment scenario?
