Cloud 66 Starter
Generate Dockerfile and service.yml
Cloud 66 Starter
Cloud 66 starter is an open-source command line tool to generate a Dockerfile and a service.yml file from arbitrary source code. The service.yml file is a Cloud 66 service definition file which is used to define the service configurations on a stack.
Starter works in the same way as BuildPacks do, but only generates the above mentioned files; the image compile step happens on the BuildGrid. Starter does not require any additional third party tools or frameworks to work (it’s compiled as a Go executable).
To get started download the executable and run it on your development machine.
$ cd /my/project $ starter
This will analyze the project in the current folder and generate the two files: Dockerfile and service.yml in the same folder, prompting for information when required.

Starter supports Procfiles and generates a service in service.yml for each item in the Procfile. It is strongly advised to use a Procfile to define your own service commands, as starter will only detect the web service otherwise.
To use starter on a different folder, you can use the
$ starter -p /my/project
For more options, please see:
$ starter --help

Contributing & Adding support for new frameworks and languages
We will be adding support for new languages and frameworks over the time. However, if you find yourself interested in adding one, it’s fairly easy to do:
- Get the source code and compile it (it’s written in Go!)
- Create a new directory under
packs/for you language or framework, e.g
- You then need to implement two interfaces,
