03/15/2023, 2:14 PMYou’re right, the documentation could probably be a bit clearer on what “provider ID” really is. There’s oblique reference to this in https://www.pulumi.com/docs/intro/concepts/resources/names/#resource-names (as the physical name), and further clarification in https://www.pulumi.com/docs/intro/concepts/resources/get/, but the term “provider ID” isn’t defined anywhere (or, IIRC, used entirely consistently).

03/15/2023, 2:25 PMDo you know why Pulumi decided to make resource_name, id mandatory when we can use tags when doing a SecurityGroup.get()? We're using terraform data and we only supply tags to find the resource property like id, arn, etc.

Copy code

resource_name=existing_security_group_name,
id="sg-aaaaaaaaaaaaaaa",

03/15/2023, 2:45 PMI'm good. I got it working. I had to use ids property and set index to zero

03/15/2023, 3:51 PMYes, it’s a list, so there’s a need to encode the assumption that it should only ever match one resource in your case (you may indeed want some sort of code to check for that), or you could just attach all SGs that you get back (which is more generalized, but may swallow a misconfiguration if you will never be needing that in your use case).
