This set of modules creates specialized [cloud-config](https://cloud.google.com/container-optimized-os/docs/how-to/run-container-instance#starting_a_docker_container_via_cloud-config) configurations, which are designed for use with [Container Optimized OS](https://cloud.google.com/container-optimized-os/docs) (the onprem module is the only exception) but can also be used as a basis for other image types or cloud providers.
All modules are designed to be as lightweight as possible, so that specialized modules like [compute-vm](../compute-vm) can be leveraged to manage instances or instance templates, and to allow simple forking to create custom derivatives.
To use the modules with instances or instance templates, simply set use their `cloud_config` output for the `user-data` metadata. When updating the metadata after a variable change remember to manually restart the instances that use a module's output, or the changes won't effect the running system.
