+description: |-
+  Get an elastic beanstalk solution stack.
+---
+
+# aws\_elastic\_beanstalk\_solution\_stack
+
+Use this data source to get the name of a elastic beanstalk solution stack.
+
+## Example Usage
+
+```hcl
+data "aws_elastic_beanstalk_solution_stack" "multi_docker" {
+  most_recent   = true
+
+  name_regex    = "^64bit Amazon Linux (.*) Multi-container Docker (.*)$"
+}
+```
+
+## Argument Reference
+
+* `most_recent` - (Optional) If more than one result is returned, use the most
+recent solution stack.
+
+* `name_regex` - A regex string to apply to the solution stack list returned
+by AWS.
+
+~> **NOTE:** If more or less than a single match is returned by the search,
+Terraform will fail. Ensure that your search is specific enough to return
+a single solution stack, or use `most_recent` to choose the most recent one.
+
+## Attributes Reference
+
+* `name` - The name of the solution stack.
