Hi Team,

Trying to configure elastic search via helm chart.
Please find the below are steps.

helm create ele

I have increased the vm.max_map_count
sysctl -w vm.max_map_count=262144

Still getting same error "Elasticsearch: Max virtual memory areas vm.max_map_count [65530] is too low, increase to at least [262144]"

I was able to configure elastic search on docker and kubernet.....
Using same image and ending up with error.

Please do the needful.

Thanks
