+description: |-
+  Provides a list of AMI IDs.
+---
+
+# aws\_ami_ids
+
+Use this data source to get a list of AMI IDs matching the specified criteria.
+
+## Example Usage
+
+```hcl
+data "aws_ami_ids" "ubuntu" {
+  owners = ["099720109477"]
+
+  filter {
+    name   = "name"
+    values = ["ubuntu/images/ubuntu-*-*-amd64-server-*"]
+  }
+}
+```
+
+## Argument Reference
+
+* `executable_users` - (Optional) Limit search to users with *explicit* launch
+permission on  the image. Valid items are the numeric account ID or `self`.
+
+* `filter` - (Optional) One or more name/value pairs to filter off of. There
+are several valid keys, for a full reference, check out
+[describe-images in the AWS CLI reference][1].
+
+* `owners` - (Optional) Limit search to specific AMI owners. Valid items are
+the numeric account ID, `amazon`, or `self`.
+
+* `name_regex` - (Optional) A regex string to apply to the AMI list returned
+by AWS. This allows more advanced filtering not supported from the AWS API.
+This filtering is done locally on what AWS returns, and could have a performance
+impact if the result is large. It is recommended to combine this with other
+options to narrow down the list AWS returns.
+
+~> **NOTE:** At least one of `executable_users`, `filter`, `owners` or
+`name_regex` must be specified.
+
+## Attributes Reference
+
+`ids` is set to the list of AMI IDs.
