+# cloudfoundry_buildpacks (Data Source)
+
+Gets information of Cloud Foundry buildpacks present.
+
+## Example Usage
+
+```terraform
+data "cloudfoundry_buildpacks" "buildpack" {
+  name = "java_buildpack"
+}
+
+output "buildpack" {
+  value = data.cloudfoundry_buildpacks.buildpack
+}
+```
+
+<!-- schema generated by tfplugindocs -->
+## Schema
+
+### Optional
+
+- `name` (String) Name of the buildpack to filter by
+- `stack` (String) The name of the stack to filter by
+
+### Read-Only
+
+- `buildpacks` (Attributes List) The list of buildpacks (see [below for nested schema](#nestedatt--buildpacks))
+
+<a id="nestedatt--buildpacks"></a>
+### Nested Schema for `buildpacks`
+
+Required:
+
+- `name` (String) Name of the buildpack
+
+Optional:

+- `annotations` (Map of String) The annotations associated with Cloud Foundry resources. Add as described [here](https://docs.cloudfoundry.org/adminguide/metadata.html#-view-metadata-for-an-object).
+- `enabled` (Boolean) Whether or not the buildpack can be used for staging
+- `labels` (Map of String) The labels associated with Cloud Foundry resources. Add as described [here](https://docs.cloudfoundry.org/adminguide/metadata.html#-view-metadata-for-an-object).
+- `locked` (Boolean) Whether or not the buildpack is locked to prevent updating the bits
+- `position` (Number) The order in which the buildpacks are checked during buildpack auto-detection
+- `stack` (String) The name of the stack that the buildpack will use
+
+Read-Only:
+
+- `created_at` (String) The date and time when the resource was created in [RFC3339](https://www.ietf.org/rfc/rfc3339.txt) format.
+- `filename` (String) The filename of the buildpack
+- `id` (String) The GUID of the object.
