polymathrobotics/cinc repository overview

⁠cinc

This image packages Cinc Client⁠ binaries as a data container that can be used with kitchen-dokken⁠.

A data container is an older pattern used more commonly before named volumes were supported in Docker. A data container is an image used to pre-populate data for other containers. Kitchen-dokken uses this data container to avoid needing to install the chef-client in new Test Kitchen instances and other cookbook -related data. The --volumes-from parameter is used to load the volumes mounted in the data container when a Test Kitchen test instance is run. A data container is used instead of a named volume because Test Kitchen uses a mix of bind mounts and volumes mounts to share data, so a container is needed.

Modify your kitchen.yml similar to the following in order to use cinc instead of chef in Test Kitchen:
