elasticsearch_curator_instance_id: "{{ groups['elasticsearch-curator'].index(inventory_hostname) }}"

# How frequently Curator runs.
# For multinode deployments of Curator you should ensure each node has
# a different schedule so that Curator does not run simultaneously on
# multiple nodes. Use hostvars or parameterize like in the default
# below.
# The default depends on Curator's id as defined above which dictates
# the daily hour the schedule runs (0, 1, etc.).
