Cri File System Tools Install 〈2026〉

Create a test process holding open a file:

echo "test data" > /tmp/testfile
tail -f /tmp/testfile &
PID=$!
sudo criu dump -t $PID --shell-job --ext-files -D /tmp/criu_dump
sudo criu restore -D /tmp/criu_dump --shell-job

If the restore succeeds, the filesystem interactions were preserved.

sudo umount -l /run/containerd/io.containerd.runtime.v2.task/k8s.io/*/rootfs cri file system tools install

crictl is the Swiss Army knife for CRI-compliant runtimes. It allows you to list containers, pull images, and execute commands inside a container’s filesystem.

For the latest version (bypassing package managers): Create a test process holding open a file:

VERSION="v1.30.0"
curl -L https://github.com/kubernetes-sigs/cri-tools/releases/download/$VERSION/crictl-$VERSION-linux-amd64.tar.gz | sudo tar -xz -C /usr/local/bin

Verification:
crictl --version
crictl info (shows runtime configuration)

You need go (Golang) and make installed. If the restore succeeds, the filesystem interactions were

sudo apt-get update
sudo apt-get install -y golang-go make git

sudo apt-get update sudo apt-get install -y cri-tools
