Deletion of indices action not enforced

kasim123 · March 8, 2021, 1:22pm

Hi Team,

I deployed EFK stack in my cluster with default settings except storage size and secrets settings. Everything is working so far. Now, I wanted to configure elasticsearch curator for managing indices in elasticsearch cluster. I already configured it with one action rule which deletes indices which are 90 days old. But the problem is, the action rule is not enforced and it is not deleting old indices from the cluster.

Here is the output of curator pod. Could anyone guide me what is missing in the rule.

2021-03-08 01:00:07,786 DEBUG          curator.indexlist       empty_list_check:226  Checking for empty list
2021-03-08 01:00:07,787 INFO                 curator.cli                    run:180  Skipping action "delete_indices" due to empty list: <class 'curator.exceptions.NoIndices'>

I had gone through one github issue and it is being mentioned to use allow_ilm_indices: true in action.yaml. I made that change too. Still It did not help me. I did not configure any Index lifecycle management settings in Elasticsearch settings.

Here is my action.yaml file output.

This message simply implies that with all filtering having been done, no matching indices remain to act on. More of the debug log will be necessary to fully troubleshoot what happened.

Here is the output of cronjob pod which was triggered today. I deleted few of the index names, but the cluster has indexes which are 90 old.

You have configured a unit_count of 90 unit's (days), and 90 days ago by my calculations is 8 December 2020. I do not see any indices that old in the output you shared, so it makes sense to me that no indices would be deleted.
