Elasticsearch - disable swapping

[Doweig]

Hello guys,

I am currently trying to optimize Elasticsearch in production.
I have noticed that is it recommended to disable memory swapping in production and the official documentation is giving 3 ways to accomplish that:

https://www.elastic.co/guide/en/elasticsearch/guide/current/heap-sizing.html#_swapping_is_the_death_of_performance

1- sudo swapoff -a + edit /etc/fstab
2- Change the sysctl value, vm.swappiness = 1
3- Change java options by editing elasticsearch.yml, bootstrap.mlockall: true

Inside the docker image however, none of there 3 ways have been implemented

Is it something that should be handled on docker level or on the system level ?

Thank you in advance guys!
