WARNING#

1
Elasticsearch requires some changes in the kernel of the host machine to
2
work as expected. If those values are not set in the underlying operating
3
system, the ES containers fail to boot with ERROR messages.

This chart uses a privileged initContainer to change those settings in the Kernel

by running: sysctl -w vm.max_map_count=262144 && sysctl -w fs.file-max=65536
