Its recommended to disable swap in the elasticsearch machine, but I was wandering if I have three elastic nodes on docker, is still recommended to disable swap?

The recommendation is to disable swap completely amongst [other 2 options](https://www.elastic.co/guide/en/elasticsearch/reference/7.7/setup-configuration-memory.html) to ensure elasticsearch JVM uses RAM, this also applies when using docker.  
For docker specific on limiting at container level (if the docker host/engine has swap enabled), best to refer to [docker documentation](https://docs.docker.com/config/containers/resource_constraints/#limit-a-containers-access-to-memory)

Thanks Julien, if I disable swap on linux then it wouldn't be necessary to disable it in docker right?
