That looks like the vm.max_map_count issue that was part of #98. We added some info to the docs on how to fix it:

Note: since 5.0, Elasticsearch only listens on localhost by default, so this image sets network.host to 0.0.0.0 (given that localhost is not terribly useful in the Docker context).

As a result, Elasticsearch is more strict about the bootstrap checks that it performs, especially when checking the value of vm.max_map_count which is not namespaced and thus must be set to an acceptable value on the host (as opposed to simply using --sysctl on docker run).

I follow the doc and i fix that config as mention for vm.max_map_count but on this case was for ulimits. i fix it with following config on my docker-compose.yml

ulimits:
    nofile:
       soft: 65536
       hard: 65536
