Support for Elasticsearch v8

[preyas-prakasan]

Hello,
We are planning to upgrade our clusters from v7 to v8 and use your provider in our terraform code. Wanted to see if we can get the provider support for ES v8.

Is that in the pipeline ?

👋 Hi at this time, I think I'm recommending that for v8 support users switch to the Elastic provider: https://github.com/elastic/terraform-provider-elasticstack. Are there specific resources not supported yet in the official provider that you're using?

I understand that could be challenging to switch a lot of resources, I believe an interim step could be to set the elasticsearch_version argument on the provider explicitly: https://registry.terraform.io/providers/phillbaker/elasticsearch/latest/docs#elasticsearch_version. (E.g. when connecting to a v8 cluster, set the version to v7.x.x)

We don't currently use this provider but are evaluating it.

There is definitely quite a few resources the official provider cannot manage, but this one can. The official provider mostly only had resources for indexes, ingest pipelines and some security components.

Mostly, there is no support for any of the Kibana functions (alerts are of particular interest to us). There is no indication that any of this on their roadmap, or if there is any expectation of a separate provider for the Kibana api (e.g. nothing but crickets here elastic/terraform-provider-elasticstack#48)

I was pointed in the general direction of this repo when raising questions around Kibana Alerting automation by our Elasticsearch representatives. I would be interested in knowing if you expect to maintain/embellish the Kibana support going forward (independant of support ESv8 if that is not on the cards) or if we should look elsewhere.

Update: It looks like the Kibana issue seems has been added to a 0.4.0 milestone for the official provider (without comment) – so it looks like Kibana api support may be in the official provider as of the next major version ?

As far as I understood official ES provider lacks support of AWS auth which makes it less usable in case of using with AWS hosted clusters. :(

FYI: just found that author of this project have started a fork of official elastic provider to support opensearch - https://github.com/opensearch-project/terraform-provider-opensearch

Unfortunately there's no releases yet, and it seems it's still on early steps.

P.S. Just looked into the code and now it seems that's a rebranding of this project, not a fork of elastic official provider
