CLI and validation tools for Kubelet Container Runtime Interface (CRI) .

Build Status Go Report Card

What is the scope of this project?

cri-tools aims to provide a series of debugging and validation tools for Kubelet CRI, which includes:

  • crictl: CLI for kubelet CRI.
  • critest: validation test suites for kubelet CRI.

What is not in scope for this project?

  • Building a new kubelet container runtime based on CRI.
  • Managing pods/containers for CRI-compatible runtimes by end-users, e.g. pods created by crictl may be removed automatically by kubelet because of non-exist on the kube-apiserver.
