This docker image runs curator tasks against an elasticsearch cluster to manage its indices.
The list of tasks currently are:
- purge old logstash indices (when MAX_INDEX_AGE is set)
- optimise logstash indices that are a day old or more
ELASTICSEARCH_HOST - The hostname or IP address of an elasticsearch cluster.
INDICES_PREFIXES - Prefixes of indices to optimize/purge, space separted. Defaults to "logstash"
MAX_INDEX_AGE - The maximum age (in days) a logstash index can be until it is deleted.
