Example of how to use curator and elasticsearch python api to update index settings

elasticsearch-update-settings.py

import elasticsearch
import curator
import json

client = elasticsearch.Elasticsearch()
indices = curator.get_indices(client)

# Filter anything older than or equal to 3 days
_filter = curator.build_filter(kindOf='newer_than', value=3, time_unit='days', timestring='%Y.%m.%d')
indices = curator.apply_filter(indices, **_filter)

# Filter anything newer than or equal to 1 day
_filter = curator.build_filter(kindOf='older_than', value=1, time_unit='days', timestring='%Y.%m.%d')
indices = curator.apply_filter(indices, **_filter)

for index in indices:
    put = client.indices.put_settings(
        index=index,
        body='''{
            "index": {
                "refresh_interval": -1,
                "blocks.write": true
            }
        }''',
        ignore_unavailable=True
    )

    if 'acknowledged' not in put or put['acknowledged'] != True:
        raise Exception('Failed to update index: %s\n\n%s' % (index, json.dumps(put)))
