Elasticsearch

This is a repo achieves three things -

  • A preconfigured elasticsearch.yml

    In this config file we disable nmap as Elasticsearch requires vm.max_map_count to be set to 262144 when the default is 65530.

    This is needed because changing vm.max_map_count Would not be possible on most cloud hosted providers.

  • Chmod's the /esdata directory with the elasticsearch user.

    The volumes are mounted as root but elasticsearch is ran as non-root.

    This is needed because elasticsearch needs to write to the volume.

  • Add an anonymous user that is able to perform a healthcheck to make sure the service is running
