I've submitted a PR for this to docker-py in docker/docker-py#1145. I have a patch for docker-compose in my tree at 87ea3c4. Will submit my patch here once docker-py support is accepted.

Anything happening here?

#3798 closes this. docker-py version 1.10.0 added support for sysctls, so I hope we can get this merged soon.

I followed instruction https://docs.docker.com/compose/gettingstarted/ . but it does not work ......

Has anyone got the instruction working?

Guys any progress? Need this feature to run latest version of Elasticsearch from docker-compose...

Guys sorry for annoying, when it becomes available in release?

FYI

There is sysctls option starting from docker-compose 2.1

Docker-compose 3.0+ support this feature (sysctls)?

@agiUnderground, yes
