After you have modified an existing buildpack or created your own, it is necessary to maintain it.
See the following topics to maintain your own buildpacks:
To configure a production server for your web app, see Configuring a production server.
For information about updating and releasing a new version of a Cloud Foundry buildpack through the Cloud Foundry Buildpacks Team Concourse pipeline, see Using CI for buildpacks. You can use this as a model when working with Concourse to build and release new versions of your own buildpacks.
