Hi all,
I am trying to set up stack monitoring using docker via docker compose.
Here is a sample I found on the Internet that uses the ELASTICSEARCH\_HOSTS variable. I'd like to define more in this section like the module to be used etc.
```auto
metricbeat:
image: docker.elastic.co/beats/metricbeat:7.11.1
environment:
ELASTICSEARCH_HOSTS: http://node01:9200
volumes:
- metricbeat-data01:/usr/share/metricbeat/data
networks:
- es-network
depends_on:
- node01
```
I'd like to configure as much as possible directly via docker compose, but I cannot find a detailed list of available environment variables. Could you please share the list or even better provide a link to the correct documentation side?

Hi @TobiasSackmann
There are some ways you can configure metricbeat without having to edit the file:
- You can create a configuration file that uses some environment variables as [explained in our docs](https://www.elastic.co/guide/en/beats/libbeat/8.0/config-file-format-env-vars.html)
- Use [CLI arguments](https://www.elastic.co/guide/en/beats/libbeat/8.0/config-file-format-cli.html) to override some elements from the configuration file
The docker image you're using uses a [configuration file that reads from environment variables](https://github.com/elastic/beats/blob/main/deploy/docker/metricbeat.docker.yml), it has got something like that:
```auto
output.elasticsearch:
hosts: '${ELASTICSEARCH_HOSTS:elasticsearch:9200}'
username: '${ELASTICSEARCH_USERNAME:}'
password: '${ELASTICSEARCH_PASSWORD:}'
```
Hence the values you can configure using environment variables.

The problem is not the output.Elasticsearch section which is filled by the
ELASTICSEARCH\_HOSTS variable. I would rather need the kibana equivalent to fill this section.
```auto
setup.kibana:
host: 'kibana:5601'
```
Currently the setup.kibana part is completely missing when I have a look at the metricbeat.yml within the docker container.
Unfortunately, none of your links provides a full list of variables nor does the metricbeat.reference.yml within the docker container.
A full list of environment variables that are processed would be appreciated(or at least the one for the kibana hosts).
Kind regards
Tobias
