OpenSearch v3 Curator Support

OpenSearch
1

Hello, we was using OpenSearch v2 with old version of curator and used storage based retention per index pattern (storage it consumes from node). Now we are willing to upgrade to OpenSearch v3 and we see we need to remove compatibility.override_main_response_version and it breaks the curator

ERROR Elasticsearch version 3.2.0 incompatible with this version of Curator (5.7.6)

is there any way to make OpenSearch v3 continue working with old curator? or is there any alternative to curator but work in similar form with little changes?

We aware of ISM but it looks like ISM can’t do what we do with curator, we basicly keeping the cluster utilised in mos optimal manner, like when defined space/storage threshold reached start deleting on indices…

Hi @bakili ,

Did you manage to find a workaround? I did some testing and found this curator-opensearch works well and with version 3.2.0. GitHub - flant/curator-opensearch: Curator for OpenSearch.

What was the issue to why ISM wouldn’t work well?

@Leeroy for now we delayed the upgrade of OpenSearch that is why not checked yet. Thanks for the project, we will check

What was the issue to why ISM wouldn’t work well?

we use store size based retention per index pattern from curator which is not supported on ISM
