 ```bash
 make cri-integration

 ## CRI Validation Test
 [CRI validation test](https://github.com/kubernetes-sigs/cri-tools/blob/master/docs/validation.md) is a test framework for validating that a Container Runtime Interface (CRI) implementation such as containerd with the `cri` plugin meets all the requirements necessary to manage pod sandboxes, containers, images etc.
