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

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.

• 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.

Version matrix:

See the roadmap for information about current and future milestones.

The releases are in tandem with Kubernetes releases in general. As referenced in above version matrix, since release 1.16, we maintain master branch of this repo. However, for critical fixes in previous releases, we would only consider the releases which are still not EOL in Kubernetes releases.
