How to check running application's buildpack In cloudfoundry?

I have many buildpacks deployed, is it possible to check used buildpacks on running application?

Two|Three Stepped Process worked for Cloud Foundry api version: 2.141.0:

  1. Retrieve the GUID of the application using cf app <app_name> --guid - API Doc
  2. Get App summary using above GUID cf curl /v2/apps/:APP-GUID/summary - API Doc
  3. Search for "buildpack" in result, should be there - something like this enter image description here

If "buildpack" not found then follow instructions post from @Smile - Adding here for easier read.

  1. Search for "detected_buildpack_guid" in above result, e.g. enter image description here
  2. Retrieve Buildpack information using above GUID cf curl /v2/buildpacks/:guid - API Doc, then search for filename in results, e.g., enter image description here

Note: Make sure to login into CloudFoundry before executing this commands.

You can do it multiple ways..

You can install buildpack-usage cf cli plugin. You can find it here or here

The other option is to do $> cf curl "/v2/apps"

Check out Cloud Foundry API

Give it a try. Let me know if you have any questions.

In addition to Abhijeet's answer, in case you get buildpack attribute as null or empty, you can get the buildpack guid from detected_buildpack_guid attribute and call buildback API like

cf curl /v2/buildpacks/:BUILDPACK-GUID

Solution 4:[4]

This can be fetched from the below V3 APIs.

  1. Get the list of Application GUIDs:

    cf curl '/v3/apps'

  2. Get the relevant buildpacks and its version:

    cf curl /v3/apps/AppGUID/droplets/current
