Elasticsearch docker image acts differently on a different host OS

(jacekr) #1

hi Elasticsearch,

I'm trying to run ES docker image docker.elastic.co/elasticsearch/elasticsearch:5.2.2 so that it binds the port 9300 on non LO interface, so that other containers can connect to that port.

My tests suggest, that depending on the host OS, the container behaves in a different way.

  • on windows host, it works fine, 9300 will be set to by default
  • on linux host (Centos 7) it will be set to and when I try to change that by passing env. variable transport.host: it fails with the following log:

I'm running the container in this way:
docker run -d --name kadme_elastic -e "transport.host=" docker.elastic.co/elasticsearch/elasticsearch:5.2.2

Setting the vm.max_map_count to the advised number does not help.
The container exits after some time.

this helped in our case -
sudo sysctl -w vm.max_map_count=262144
