How do I use opensearch with a t2.small.search or t3.small.search instance?

0

After accidently incurring absorbent charges for basically not using opensearch at all (but on a large instance), I am looking to create a domain using a free tier instance. However, when creating a domain, t2.small.search and t3.small.search do not show up as instance options. Is a certain opensearch version required?

Any ideas? Thank you

Hello.

Terms of use for t2.small.search or t3.small.search are described in the following documents:
https://docs.aws.amazon.com/opensearch-service/latest/developerguide/supported-instance-types.html

When I selected "Domain without standby" when creating the domain, I was able to select "t3.small.search".

  • Thanks, I was able to use a small instance by selecting domain without standby like you said. I feel like this should be documented better. I don't think that is mentioned in the doc you linked.

  • As of November 2024, even with "Domain without standby" selected the smallest instance I'm able to select is "r7g.medium.search." If anyone can guide me to a "t3.small.search" instance I'd still love to go that route. But if "r7g.medium.search" is truly the smallest/cheapest option, AWS needs to stop baiting prospective users with "free tier" promises. I was just billed $90 for running a totally empty OpenSearch instance for one week. All I did was follow this "free tier" tutorial, recorded by an actual AWS Solutions Architect a year ago - https://www.youtube.com/watch?v=SIl5PM4m2KM.
