+There are also integration tests in the `molecule` directory which are meant to be run against a local Kubernetes cluster, e.g. using [KinD](https://kind.sigs.k8s.io) or [Minikube](https://minikube.sigs.k8s.io). To run the tests, set up a local cluster, then run Molecule:

 ## Publishing New Versions
 
 The current process for publishing new versions of the Kubernetes Collection is manual, and requires a user who has access to the `community.kubernetes` namespace on Ansible Galaxy to publish the build artifact.
