@dm3ch now this PR duplicates PR https://github.com/cloudposse/terraform-aws-elasticsearch/pull/149 The PR contains issues that break our tests.

Can you leave in the PR only code related to cold storage support

Thanks.

[dm3ch]

@goruha Yep, merged the wrong branch.

Now dropped unwanted changes from this PR.

@goruha I'm not sure how to better fix this test.

I even don't understand why the test tries to enable cold storage if I haven't modified any tests and made it disabled by default.

[goruha]

@dm3ch it does not enable cold storage. I says that it do not support that cold storage configuration block at all

Error: creating Elasticsearch Domain (eg-test-es-test-10332): ValidationException: Your domain's Elasticsearch version does not support cold storage options. Upgrade to Elasticsearch 7.9 or later.

I think you have to make this block dynamic

[dm3ch]

Ok, wrapped to dynamic block

@dm3ch LGTM
