I run elasticsearch in kubernetes cluster provided by amazon eks.

For deploy, I use the official helm chart.

After deploying elasticsearch pods failed on bootstrap:

ERROR: [1] bootstrap checks failed
[1]: max file descriptors [4096] for elasticsearch process is too low, increase to at least [65536]

I try to change limits.conf into a container and into an instance node. But error continues to occur.

How I can solve this issue and increase the number of max file descriptors for elasticsearch pod?
