In the rapidly evolving landscape of cloud-native development and container orchestration, the underlying infrastructure often becomes an opaque black box. For developers and system administrators working with Kubernetes, containerd, or CRI-O, one acronym repeatedly surfaces when debugging storage issues: CRI.
In DevOps and cloud engineering, cri-tools is a set of CLI utilities (like crictl) used to interact with the Container Runtime Interface (CRI). These are essential for debugging nodes when you aren't using the Docker CLI. How to Install crictl cri file system tools install
Furthermore, "CRI filesystem tools" colloquially includes snapshotter plugins like overlayfs, native, zfs, or btrfs drivers that the container runtime uses to manage container layers. Mastering Container Storage: The Ultimate Guide to CRI
crictl: A CLI for sandbox and container management, similar to the Docker CLI but tailored for CRI runtimes. These are essential for debugging nodes when you
images / img: Lists available container images stored in the runtime's local storage.
To test if your filesystem tools work, convert a standard OCI image (like Nginx) into the Nydus format.
