Include a default index-lifecycle policies

[tdmakepeace]

by default no index life cycle policy is defined, so when you attempt to create one, any index created prior to the creation of the new index-lifecycle-policy has to be manually managed.
by creating and assigning a default policy, it can be edited, or a new one created, but it means all existing indexes are still managed from a lifecycle perspective.

[tdmakepeace]

To set an index policy the status needs to be green, if you are running a single node, then you need to update the default replicas to "0"

example.

curl -q -s "http://localhost:9200/_cat/shards" |grep UNASSIGNED |cut -c 1-25

curl -X PUT -H "Content-Type: application/json" "http://localhost:9200/pensando-fwlog-2024.02.21/_settings" -d '{ "number_of_replicas": 0 }'
