itzg/elasticsearch-curator repository overview

This image will periodically run elasticsearch-curator⁠.

⁠Configuration Environment Variables

• PERIOD : defines period (in seconds) between runs of curator; default is 86400 seconds (1 day)
• ES_HOST : defines the hostname of the Elasticsearch node to contact; default is master
• DELETE_AGE : defines what age (and older) of indices will be deleted; defaul is 45

⁠Configuration filters

The image comes with basic, but functional, configuration files that utilize the environment variables above. The actions configuraion will delete indices that are prefixed with "logstash-" or "metricbeat-" that are older than $DELETE_AGE.

The configuration files are:

• /etc/curator/config.yml
• /etc/curator/actions.yml

One or both may be replaced by extending images or with -v attachment over the directory or file.
