Hi Guys,

I installed elastic search using the below link with docker image.  
[https://elk-docker.readthedocs.io/#installation](https://elk-docker.readthedocs.io/#installation)

But when I start elastic search docker file using following command,  
`sudo docker run -p 5601:5601 -p 9200:9200 -p 5044:5044 -it --name elk sebp/elk`

But getting an error,  
`max file descriptors [4096] for elasticsearch process is too low, increase to at least [65536]`

When I check my `ulimit -n` it gives the result 65536, then how can this be resolved?

Thanks.

Hi,

Can you set MAX\_OPEN\_FILES variable ? ([https://elk-docker.readthedocs.io/#overriding-variables](https://elk-docker.readthedocs.io/#overriding-variables)).  
Ex : add `-e MAX_OPEN_FILES 65536`

Regards,  
Grégoire
