Troubleshouting

Elasticsearch host inavailable within a container

When Elasticsearch is launched inside a container it is inaccessible from another linked container. A configuration has to be set for it to work properly. Change IP as needed.

  docker run --name=elasticsearch elasticsearch elasticsearch -Etransport.host=0.0.0.0

In order to pass the bootstrap checks you will also need to run that command on the host machine:

  sysctl -q -w vm.max_map_count=262144
