I need to access elasticsearch logs of elasticsearch cluster running within docker containers.  
Volumes: - /mnt/ssd1/eslog1:/var/log/elasticsearch  
is not the option , all logs are by default send to stdout and accessible only via

> docker logs es-node21

How I can access the logs,  
I am thinking of filebeat elasticsearch module to collect the logs into elasticsearch.

This is my docker-compose.yml

> version: '3.3'  
> services:  
> es-node21:  
> image: [docker.elastic.co/elasticsearch/elasticsearch:7.4.2](http://docker.elastic.co/elasticsearch/elasticsearch:7.4.2)  
> container\_name: es-node21  
> restart: always  
> environment:  
> - node.name=es-node21  
> - "discovery.zen.ping.unicast.hosts=node3.corp,node2.corp"  
> - http.cors.enabled=true  
> - http.cors.allow-origin=\*  
> - cluster.name=cem-docker-cluster  
> - bootstrap.memory\_lock=true  
> - "ES\_JAVA\_OPTS=-Xms24g -Xmx24g"  
> ulimits:  
> memlock:  
> soft: -1  
> hard: -1  
> volumes:  
> - /mnt/ssd1/esdata1:/usr/share/elasticsearch/data  
> - /mnt/ssd1/eslog1:/var/log/elasticsearch --- this logging does not work need to be done another way!!

Hi @Petr.Simik

To get Elasticsearch write the logs to file you either need to do some hacky stuff with docker and the command parameters or modify the log4j2.properties file. I advise you to check out the following site:  
[https://www.elastic.co/guide/en/elasticsearch/reference/current/logging.html](https://www.elastic.co/guide/en/elasticsearch/reference/current/logging.html)

You need to map the new log4j2.properties to the containers and also need a folder mapped into the directory you want to save the logs.

Hope this leads you on the right way.
