crictl is the Swiss Army knife for any CRI-compliant runtime. While it does not directly create filesystem links, it provides the metadata necessary to locate images and containers on disk.
Key commands for filesystem inspection:
crictl images # Lists images with their IDs and sizes
crictl inspect <container-id> # Shows detailed mount points and layer paths
crictl imagefsinfo # Reports filesystem usage for image storage
The "Link" Discovery: The inspect command reveals the rootfs path—a symbolic link that points to the container’s writable layer. For example:
"info":
"rootDir": "/var/lib/containerd/io.containerd.runtime.v2.task/k8s.io/<container-id>/rootfs"
Enable game developers and modders to efficiently manage CRI middleware file systems (e.g., .cpk archives used in CRIWARE). The tools provide robust linking between virtual file system entries and physical assets, supporting streaming, patching, and runtime file replacement.
CRI-O uses storage package (from containers/storage) with tools like: cri file system tools link
The Container Runtime Interface (CRI) is a plugin interface for Kubernetes container runtimes. It allows Kubernetes to work with different container runtimes, providing a standard way to interact with the container runtime. This interface is crucial for ensuring that Kubernetes can manage containers across various environments and runtimes.
