+# Data Source: aws_elastic_beanstalk_application
+
+Retrieve information about an Elastic Beanstalk Application.
+
+## Example Usage
+
+```hcl
+data "aws_elastic_beanstalk_application" "example" {
+  name = "example"
+}
+
+output "arn" {
+  value = "${data.aws_elastic_beanstalk_application.example.arn}"
+}
+
+output "description" {
+  value = "${data.aws_elastic_beanstalk_application.example.description}"
+}
+```
+
+## Argument Reference
+
+* `name` - (Required) The name of the application
+
+## Attributes Reference
+
+* `id` - The name of the application
+* `arn` - The Amazon Resource Name (ARN) of the application.
+* `description` - Short description of the application
+
+Application version lifecycle (`appversion_lifecycle`) supports the nested attribute containing.
+
+* `service_role` - The ARN of an IAM service role under which the application version is deleted.  Elastic Beanstalk must have permission to assume this role.
+* `max_count` - The maximum number of application versions to retain.
+* `max_age_in_days` - The number of days to retain an application version.
+* `delete_source_from_s3` - Specifies whether delete a version's source bundle from S3 when the application version is deleted.
