This expression searches through records that look like this

In the above example, you can see that the name is amzn2-ami-hvm-2.0.20220218.1-x86_64-gp2, so that matches amzn2-ami-hvm*
The results are sorted in descending order of CreationDate and the first from the sorted list is chosen by most_recent = true
You use it like this
resource "aws_instance" "my_instance" {
ami = data.aws_ami.app_ami.image_id
Hi Alistair,
Thank you very much for your respond But could you please share wıth me what ıs the resource of this information. what can be the other ImageOwnerAlias and ImageLocations values? I would like to see any resource about this matter.
Owner is usually an AWS account ID. Some well known accounts have aliases, like Amazon’s own. Generally if you are searching for an AMI it will be from Amazon, unless you have created your own custom AMIs, then those will be in your own account.
As for filters, you can query a number of different combinations of the above properties. The names, you just get to know with experience.
See describe-images — AWS CLI 2.0.34 Command Reference which is what this data source is doing under the hood.
So to build the correct filter you have to have some idea of what you are looking for, e.g. linux/windows - if linux then amazon, ubuntu, redhat etc - it goes on
Thank you very much for your valuable informations Alistair. It was very usefull!
Regards
Best wishes.

@Alistair_KodeKloud Is there anywhere to see the “name” of the ami’s? I’m trying to see in the aws console but not having much luck. Just starting a terraform udemy course
