Subject: Add state for updating Elasticsearch index templates
X-Git-Url: https://gerrit.mcp.mirantis.com/gitweb?p=salt-formulas%2Felasticsearch.git;a=commitdiff_plain;h=refs%2Fchanges%2F11%2F16011%2F6

Add state for updating Elasticsearch index templates

To prevent index template from constant or accidential update
add separate salt state to explicit use in order to update.

To use run:
  salt -C 'I@elasticsearch:client' state.sls elasticsearch.client.update_index_templates

+Upgrade operations
+------------------
