X-mode
X-mode can be useful for debugging minimal systems that do not have a built-in shell (eg. Talos).
Here's an example of how you can debug the network for a rootless kube-apiserver container without a filesystem:
kubectl node-shell -x <node>
# Download crictl
wget https://github.com/kubernetes-sigs/cri-tools/releases/download/v1.28.0/crictl-v1.28.0-linux-amd64.tar.gz -O- | \
tar -xzf- -C /usr/local/bin/
# Setup CRI endpoint
export CONTAINER_RUNTIME_ENDPOINT=unix:///host/run/containerd/containerd.sock
# Find your container
crictl ps | grep kube-apiserver

# Find pid of the container
crictl inspect 3ff4626a9f10e | grep pid
# "pid": 2152,
# "pid": 1
# "type": "pid"
# "getpid",
# "getppid",
# "pidfd_open",
# "pidfd_send_signal",
# "waitpid",
# Go to network namespace of the pid, but keep mount namespace of the debug container
