Troubleshouting

Config file permissions

Since Metricbeat 5.3, permissions needs to comply to certain constraint in order for the service to start.

By default, this Docker Image will automatically change the permissions on your config file to make it compliant.

This behaviour can be disabled using:

  -e SKIP_CHOWN_CONFIG=true

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
