podman machine ssh bash -e <<EOF
printf '[Service]\nDelegate=cpuset\n' | sudo tee /etc/systemd/system/[email protected]/k3d.conf
sudo systemctl daemon-reload
sudo systemctl restart "user@\${UID}"
EOF

export DOCKER_HOST=ssh://core@localhost:53685
export DOCKER_SOCKET=/run/user/501/podman/podman.sock
k3d cluster create --k3s-arg '--kubelet-arg=feature-gates=KubeletInUserNamespace=true@server:*'
