I installed elastic search using the below link with docker image.
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  for elasticsearch process is too low, increase to at least 
When I check my
ulimit -n it gives the result 65536, then how can this be resolved?
