cri-tools

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

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.
