need steps to replicate

I had the same issue today. After some googling I seem to have found this is related to your host's vm.max_map_count setting.

After running sudo sysctl -w vm.max_map_count=262144 and then bin/restart inside the project dir all the containers started without a problem.

Thanks @dmanners -- I'll try to make this update shortly

[markshust]

What operating system are you two on? I am unable to replicate on macOS. The vm.max_map_count setting shouldn't have anything to do with the host, since this is a elasicsearch-container-specific setting.

[piotrkwiecinski]

It has to be set up on linux host. An additional reference: https://www.elastic.co/guide/en/elasticsearch/reference/current/vm-max-map-count.html

[markshust]

Thanks! Added to documentation. Closing this one out
